Two variants of Nvidia's RTX Spark show up on Geekbench, revealing a cut-down 18-core model — Full 20-core beats most x86 mobile chips across multi-core and single-core tests

Two new Geekbench listings for Nvidia's upcoming RTX Spark laptop superchip have surfaced, confirming a second, cut-down SKU exists with 18 CPU cores, at least in the testing phases. Both parts score remarkably close to each other, posting impressive multi-core numbers, but their single-core performance isn't special. Still, these are preliminary results on unreleased hardware, so take these numbers with a grain of salt.

The model name for the 20-core (10+10) SKU was shown as "OEMQAJ 766_MIS Product Name DV" with its clocks reported at 4.0 GHz. This chip scored 2,570 points in the single-core test and 23,126 points in the multi-core test. The second listing showed up as "OEMQAJ OEMQAJ Product" with this SKU's 18 cores divided across 10+8 core clusters, clocked at 3.9 GHz. It scored 2,541 points in the single-core test, so within 1% of the 20-core part, while the multi-core was 21,776 points, which is about 6% faster than the full-fat chip.

When you compare these numbers to other Windows-running SoCs on the Geekbench database, these multi-core numbers are among the best. The Snapdragon X2 Elite Extreme currently holds the record for the highest multi-core score with 25,075 points, so both SKUs of the RTX Spark lose to it. But when we switch to the AMD AI Max+ 395, which scores 20,609 on average in the same test, even the 18-core Nvidia chip is 5.6% faster here, and the 20-core variant is about 12% faster.

Compared to Apple's lineup, the 20-core RTX Spark is 3.3% faster than the 14-core variant of the M3 Max, which scores 22,385 points in the multi-core bench. Considering that this is pre-release hardware with unoptimized drivers, we can expect it to even beat the maxed-out M4 Pro and the base M4 Max (which hover around 25,000 points) when it officially launches. Moreover, the 18-core SKU's 21,776 points are equal to, if not more than, the base M4 Pro, which also nets around 21,700 points in the multi-core test.

That being said, the swan song falls apart when we bring up the single-core numbers. Every Apple Silicon chip from the base M3 onwards beats the 2,570 points the 20-core RTX Spark achieved in this run. Only the M2 Max with its 2,477 points is bested by the Nvidia offering, and that too by just 3.75%. Apple's current-gen base M5 is a whopping 41% faster here. On the Windows side, the Snapdragon X2 Elite and X2 Elite Extreme score roughly 3,000 points, but AMD and Intel's top-end models take a beating.

The Ryzen AI Max+ 395 only achieves 2,429 points in the single-core test, making the 20-core RTX Spark 5.8% faster, and the 18-core variant 4.6% faster. The same goes for the Ryzen AI 9 HX 370 because its 2,432 points are within the margin of error of the Strix Halo chip. Intel's highest single-core score is achieved by the Core Ultra 9 275HX at 2,467 points, making it 3% slower than the 18-core RTX Spark and 4.2% slower than the 20-core SKU. However, Intel's actual fastest chip, the Core Ultra X9 388H, scores 2,767 points, making it about 7% faster than even the 20-core RTX Spark.

Taking a look at the technical specifications, it's clear that each chip adopts a distinct strategy for the mid-range market. While Intel has optimized its architecture for a higher core and thread count along with improved interconnect speeds, AMD continues to leverage its stacked cache to maintain gaming dominance on a long-lived platform.

The Intel Core Ultra 7 270K Plus is based on the original Arrow Lake-S family, utilizing the same microarchitecture that we saw on the 265K, built using TSMC’s 3nm process. It matches the flagship 285K with a 24-core configuration (8 Lion Cove P-cores and 16 Skymont E-cores) and operates with a 125W TDP. The chip can scale to a 250W Maximum Turbo Power (MTP), which is the maximum power limit that this CPU can consume for short periods when running at maximum turbo boost frequencies

Intel has also standardized several enthusiast-level performance tweaks for Arrow Lake Refresh, most notably a 900 MHz increase in die-to-die frequency and a 400 MHz fabric speed boost. It also officially supports faster DDR5-7200, along with 20 lanes of PCIe Gen 5 and 76MB of total cache. Possibly the only major concern with the Core Ultra 7 270K Plus is the LGA 1851 platform. With Intel's next-generation Nova Lake processors expected to launch later this year, the current platform will have a relatively short lifespan, restricting any future upgrade options.

The AMD Ryzen 7 7700X3D serves as a more affordable, lower-clocked variant of the 7800X3D, featuring the same eight Zen 4 cores with a peak boost clock of 4.5 GHz. Its primary architectural strength is its 104MB of total cache including 64MB of vertically stacked L3, which is specifically tuned to eliminate memory latency bottlenecks.

The chip is rated at a 120W TDP with a 162W Package Power Tracking (PPT) limit, though it frequently operates well below these levels during gaming. A major selling point for Team Red is motherboard flexibility as the 7700X3D can be used with existing AM5 motherboards (600 and 800-series chipsets), and AMD has committed to supporting the socket through at least 2029.

⭐ Winner: Intel Core Ultra 7 270K Plus

While AMD offers a more stable platform and superior gaming efficiency thanks to its large cache size, Intel’s hardware package is more comprehensive for the price. The 270K Plus offers triple the core count, significantly higher frequencies, and faster memory support.

Across a comprehensive 16-game geomean, the AMD Ryzen 7 7700X3D holds its position as the superior gaming chip, delivering a 174.3 FPS average. This represents a 5.3% performance lead over the 270K Plus, which produced a 165.6 FPS average. While Intel's latest flagship has significantly narrowed the gap compared to the original Arrow Lake silicon, AMD’s 3D V-cache architecture continues to provide a higher performance in the majority of tested titles.

Even when examining the 1% low frame rates, which is the perceived smoothness while gaming, the 7700X3D maintains a slight edge with a 118 FPS average compared to the 115 FPS from the 270K Plus.

AMD's stacked cache gives the 7700X3D a clear edge in games that are sensitive to memory latency. For instance, in Minecraft RT, the 7700X3D delivered 144.5 FPS average, dwarfing the 89.7 FPS produced by the 270K Plus for a massive 61.1% performance advantage. We see similarly dominant leads for AMD in F1 2024, where it leads by 30.4% (201.8 vs. 154.7 FPS), and in Final Fantasy XIV, where it holds a 21.7% lead (177.7 vs. 146.0 FPS). Even in esports titles like Counter-Strike 2, the 7700X3D maintains a comfortable 7.3% lead with 707.9 FPS over Intel’s 660.0 FPS.

Intel’s Core Ultra 7 270K Plus is no slouch, however, as it leverages its higher boost frequencies and the new iBOT runtime translation layer to take the lead in several games. Intel manages a win in Hogwarts Legacy, producing 135.3 FPS for a 9.1% advantage over AMD’s 124.0 FPS, a result directly attributed to iBOT. Team Blue also edges out victories in The Last of Us Part 1 with 175.6 FPS (6% lead) and Spider-Man 2 with 207.2 FPS (5% lead).

In many other modern titles, the two processors are essentially locked in a dead heat. For example, in DOOM: The Dark Ages, the 270K Plus delivers 200.4 FPS while the 7700X3D is right beside it at 200.0 FPS. The story is similar in Flight Simulator 24, where Intel's 120.5 FPS and AMD's 114.9 FPS result in a negligible difference during actual gameplay. These results indicate that while the 7700X3D is the more consistent gaming choice, especially in cache-heavy titles, the 270K Plus is a highly competitive gaming chip that delivers impressive results for its $300 price tag.

The biggest difference between these two architectures is noticeable when analyzing power consumption and efficiency metrics.

Ultimately, the 270K Plus simply blows the competition out of the water when it comes to productivity. While the 7700X3D is a highly efficient and specialized CPU for gaming, it cannot match the raw horsepower that Intel offers. For any user whose daily routine involves video editing, 3D rendering, or heavy multitasking, the 270K Plus is the obvious choice and should be the clear favorite for a multi-purpose system.

Overclocking: Intel Core Ultra 7 270K Plus vs AMD Ryzen 7 7700X3D

While both manufacturers provide tools to squeeze extra performance from their silicon, the Intel Core Ultra 7 270K Plus is built as an enthusiast-friendly, fully unlocked processor. The AMD Ryzen 7 7700X3D, on the other hand, is a more restricted processor designed primarily for out-of-the-box gaming efficiency.

For the Intel Core Ultra 7 270K Plus, overclocking is a centerpiece of the experience. As a fully unlocked K-series SKU, it offers users granular control over per-core voltages, power limits, and clock speeds via an unlocked multiplier. While these changes can be done by entering the BIOS, one can also download the Intel XTU (Extreme Tuning Utility) software to fine tune the CPU.

One of the most significant changes seen on Arrow Lake Refresh is that Intel has standardized several high-end performance tweaks including the 900MHz die-to-die frequency bump and the 400MHz fabric speed increase. This means users receive enthusiast-level interconnect performance without necessarily needing a premium Z-series motherboard. That said, Z890 boards are still necessary as they offer sophisticated tools for manual tuning and pushing the CPU to its limits.

In contrast, the AMD Ryzen 7 7700X3D follows the same path as previous Zen 4 X3D processors including a locked multiplier, which prevents traditional manual overclocking. Users are instead limited to automated and semi-automated features like Precision Boost Overdrive 2 (PBO2) and Curve Optimizer. PBO2 allows the CPU to dynamically adjust its frequencies based on available power and thermal headroom, while Curve Optimizer enables more advanced fine-tune voltage offsets for each of the eight Zen 4 cores.

While these tools can lead to sustained higher boost clocks, the sensitive nature of the 3D V-Cache stack leads to thermal challenges that limit frequency headroom. Thus, overclocking gains on the 7700X3D are often minimal compared to the flexibility offered by the Intel chip.

⭐Winner: Intel Core Ultra 7 270K Plus

The 270K Plus is a far more overclocking-friendly product. It offers a vast suite of features that AMD simply cannot match due to its architectural restrictions and locked multiplier.

Power Consumption, Efficiency, and Cooling: Intel Core Ultra 7 270K Plus vs AMD Ryzen 7 7700X3D

This is a crucial section of the faceoff as it highlights the most significant architectural divide between these two processors. While the 270K Plus prioritizes raw performance throughput, the 7700X3D focuses on extreme efficiency. This is immediately evident in their official power ratings where Intel specifies a 125W TDP with a massive 250W Maximum Turbo Power (MTP), while AMD utilizes a 120W TDP with a 162W Package Power Tracking (PPT) limit.

In synthethic multi-threaded workloads, the difference is quite evident. While running HandBrake x265 10-bit encode, the 270K Plus consumes an average of 226W, which is more than triple the 72W required by the Ryzen 7 7700X3D. A similar trend appears in VP9 encoding, where Intel draws 184W compared to AMD’s efficient 65W. Even in lighter tasks like single-threaded y-cruncher AVX workloads, the Intel chip requires 55W while the AMD chip stays at a modest 32W. Idle power consumption also favors Team Red where the 7700X3D idles at 19W and draws 22W during YouTube playback, whereas the 270K Plus sits higher at 29W and 38W, respectively.

When we translate these power figures into efficiency metrics, AMD’s lead tends to stay ahead in most traditional benchmarks. In Cinebench 2024, the 7700X3D produces 14.4 points per watt, significantly outperforming the 10.4 points per watt from the 270K Plus. In HandBrake x265, AMD achieves a superior efficiency rating of 5W per FPS , while Intel trails at 7.56W per FPS.

However, the efficiency scatter plots provide a more nuanced look at how performance scaling impacts total energy consumption. In the Blender Classroom scatterplot, the 270K Plus delivers a much higher performance of roughly 135 samples per minute, but it consumes over 33,000 kJ of task energy. In contrast, the 7700X3D finishes with only around 60 samples per minute but uses significantly less total energy at roughly 4,500 kJ.

The HandBrake x265 scatterplot shows a similar trade-off where Intel reaches 30 FPS but consumes over 55 kJ, while AMD provides 14 FPS at roughly 36 kJ. Interestingly, the Linpack scatterplot shows the 270K Plus reaching over 850 GFLOPS with roughly 11WHr of energy, making it slightly more efficient in terms of performance-per-energy than the 7700X3D, which delivers roughly 340 GFLOPS for 10Whr.

From a cooling perspective, the 250W MTP on the 270K Plus means that it requires a robust cooling solution, like a 360mm AIO, to avoid thermal throttling during extended all-core loads. The 7700X3D is far easier to manage, remaining remarkably efficient and manageable with a mid-range air cooler. While the 270K Plus delivers class leading performance, it does so by significantly compromising efficiency in heavy workloads compared to AMD.

⭐Winner: AMD Ryzen 7 7700X3D

Pricing: Intel Core Ultra 7 270K Plus vs AMD Ryzen 7 7700X3D

The Intel Core Ultra 7 270K Plus was initially introduced with a justified $300 price tag, but you'll now find it between $300 and $320. The AMD Ryzen 7 7700X3D made its debut just last month and carries a $330 MSRP, placing it right under the 7800X3D. Essentially, there is not a major difference when it comes to the chips themselves, however, the true financial divide becomes apparent when we look at the total platform cost.

The Core Ultra 7 270K Plus demands a more substantial investment to reach its full potential. While one can opt for a B860 motherboard, a compatible Z890 motherboard is necessary in order to access premium overclocking and tuning features. These typically start around $150-$200, and can go as high as $600 packed with premium features. To handle the processor′s 250W Maximum Turbo Power(MTP) during heavy productivity tasks, a high−end 360mm AIO liquid cooler ($100-$150) or a dual-tower air-cooler ($50-$100) is recommended.

In contrast, the AMD Ryzen 7 7700X3D offers a much more budget-friendly entry point. A solid B650 motherboard can be found for around $120-$150 and the chip can be effectively cooled with a modest $50 air cooler.

Unfortunately, both platforms are held back by the ongoing global shortage of memory, which has caused prices to shoot up significantly. Since both CPUs require DDR5 RAM, builders are stuck in a RAMpocalypse where a basic 32GB kit costs over $400. This extra cost is bad news for both sides as it cancels out any price advantage.

Overall, the lower upfront platform cost makes the 7700X3D a slightly more attractive option for users prioritizing their budget. Furthermore, the AM5 socket offers a clear upgrade path through at least 2029, ensuring that your motherboard investment remains viable for future CPU generations. That is not the case with Intel, as the LGA 1851 socket is expected to be replaced once the next-generation of Nova Lake CPUs arrive.

⭐ Winner: AMD Ryzen 7 7700X3D

Ultimately, while both the chips are available at a very similar price range, the AMD Ryzen 7 7700X3D is the smarter financial play for a majority of users. Its significantly lower platform costs, superior gaming efficiency, and guaranteed platform longevity provide a level of value that the more power-hungry Intel refresh cannot quite match.

The Ryzen 7 7700X3D and Core Ultra 7 270K Plus are designed for very different users, even though they sit in roughly the same price range. Like previous X3D chips, AMD's latest processor is built with gaming in mind, using its large 3D V-Cache to deliver excellent frame rates while keeping power consumption impressively low. Intel, on the other hand, combines a 24-core design with higher clock speeds and platform improvements to create one of the strongest productivity processors in its class without giving up much gaming performance.

The final score is tied at three rounds apiece. AMD comfortably wins gaming performance, power efficiency, and platform value, three factors that matter a lot for buyers shopping in this price segment. The AM5 platform also provides a significantly longer upgrade path, allowing users to drop in future processors without replacing their motherboard.

Intel, however, deserves recognition for what it has accomplished with the 270K Plus. It delivers outstanding single- and multi-threaded performance, offers a fully unlocked overclocking experience, and narrows the gaming gap to just a few percentage points in many modern titles. If your workload includes video editing, software development, 3D rendering, or other heavily threaded applications, the 270K Plus is the obvious choice and justifies its higher power draw.

For everyone else, the Ryzen 7 7700X3D is the more compelling CPU. It offers faster gaming performance, exceptional efficiency, lower platform costs, and a future-proof AM5 ecosystem. Unless your workload regularly extends beyond gaming into demanding productivity applications, AMD's latest X3D chip is the easier processor to recommend.

Owner of original Intel 8080 pre-production layout seeks restorer — handcrafted Rubylith mask shows 5,000 transistors and interconnect patterns of the fabled 2 MHz CPU

9 August 2026 at 12:00

The owner of what is claimed to be “the original engineering copy of the Intel 8080 rubylith mask” has shared a social media shout-out, looking for a skilled restorer. From the shared photograph, this important artifact from the history of computing looks like it would benefit from remounting and reframing. Hopefully, the hand‑crafted, large‑scale sheet of red film (Rubylith) has remained in good condition under glass, though. The framed artifact is likely genuine and original, as its current owner is thought to be related to Internet Hall of Fame inductee Dan Lynch, a pivotal figure in the early Internet’s success.

In you unfurl the tweet above, you can see Tom Lynch, a self-described arborist and the owner of an AI infrastructure startup, standing behind the framed chip artwork. Folks comment on the Rubylith looking just like the one that the Intel Trinity: Andy Grove, Robert Noyce, and Gordon Moore, were photographed beside in 1978.

Rubylith is simply an adhesive, peelable red film that found favor in graphic arts and chip design before designers went digital. Engineers could cut away parts of the film to define where light would be exposed during photolithography processes. Rubyliths would often be marked with pens, tape, and overlays, especially as designs were iterated and refined ahead of tape-out.

The Intel 8080’s primary architect was Federico Faggin, and it was manually drafted in the age before modern CAD. This human-scale draft is likely 100x magnification compared to the finished processor die. Even scaled this large, it would still be quite an intricate drawing as it had to map around 5,000 transistors, traces, etc., into an approximate 20- x 16-inch sheet. The commercial Intel 8080 release ended up being manufactured on a 6 μm silicon gate process. It originally ran at 2.0 MHz clocks, but later revisions would boast clock speeds up to 3.125 MHz.

Intel’s 8080 was an important 8-bit microprocessor for both the company and the advancement of personal computing. This 8-bit CPU was the one chosen for the Altair 8800, was the original target architecture for the CP/M operating system, and would be a big influence on the later x86 architecture. We also recently wrote how the 8080 bottlenecked the Space Invaders arcade design, unintentionally resulting in the space shoot-em-up’s thrilling increase in pacing as aliens were zapped from the sky.

Hardware researcher spins up 'CPU deoptimization' project to find the slowest single x86 instruction, creates hall of shame — worst offender takes 198 billion cycles spanning 62 seconds to execute

8 August 2026 at 12:20

To optimize how software runs on hardware, instruction latency analysis looks at the time it takes for low-level instructions to execute on a processor, either to optimize the architecture or to optimize applications to run on a particular architecture. One hardware researcher, Christopher Domas (@xoreaxeaxeax on GitHub), is taking a different approach with the CPU Deoptimization leaderboard, which looks not to make Assembly instructions run as fast as possible, but as slow as possible to measure the single instruction with the highest latency.

The winner here is fxrstor64, which took 62 seconds, or over 198 billion cycles, to complete. This instruction restores the state of registers used for SIMD calculations to a 512-byte memory location. To achieve the highest (slowest) score, Domas first used their own mmiotic tool to find a high-latency area in the internal PCIe fabric, then forced the CPU to load a 512-byte state from MMIO (Memory-Mapped I/O), essentially processing all of those 512 bytes as slow as possible. That took 74 billion cycles or just over 23 seconds to complete.

Then, they went further "by starving the fabric while the load is in flight." They did so by using a series of 4-byte reads from another high-latency MMIO register, overwhelming the CPU's PCIe root complex and forcing the state restore to queue behind frivolous read ops. The next step is to use the AMX instructions available in Intel's Sapphire Rapids for xrstore64. The state area is increased from 512 bytes to 8KB, which could cause the instruction to hang for more than 1 trillion cycles.

Everyone's trying to make CPUs faster.I’m trying to make them worse.New project: CPU deoptimization.Searching for the slowest possible machine instructionsx86 single instruction record:198,002,498,236 cycles, 62 secondsThe assembly hall of shame: https://t.co/G4QnFQjsZx pic.twitter.com/WNaRPf2kRCAugust 7, 2026

The x86 leaderboard is live on GitHub now, and it looks like Domas has ARM and RISC-V leaderboards planned, as well. There are a few rules for the runs. Domas says any setup is fine, so long as only the execution of a single instruction is scored. Interruptible instructions aren't allowed, nor is scoring emulated instructions run on the handler. All times are normalized based on the CPU's base clock, and the platforms were all run without hardware modifications.

We're dealing with assembly code here, so the ranking is less about the specific instruction and more about what you're doing with that instruction.

Domas primarily used two CPUs for testing: the Intel Core i7-8559U and AMD Ryzen 7 5800H (inside the Trigkey S5). For the rdmsr instruction, however, they used a VIA Eden chip, which was a series of embedded processors from the early 2000s. The rdmsr command is used to read a model-specific register, or MSR. According to Domas, VIA "uses an undocumented register at 0x133 that gives wildly high response time." That command took 202 microseconds or 161,602 cycles to execute.

This is not the developer's first foray into wild experimentation with low-level instructions. An earlier project, called movfuscator, is a C compiler that solely uses the mov (move) command.

Amazon cracks down on 'CPU waste' among engineers as agentic AI crunch intensifies — CPU demand makes low-utilization EC2 instances a hot commodity [Updated]

7 August 2026 at 16:49

Amazon Web Services is cracking down on internal use of EC2 instances among its engineers. In May, the company reportedly met with engineers and told them to reduce CPU waste to ensure AWS has enough CPU capacity to meet customer demand, The Information reports. The message comes as demand for CPUs in the data center has hit a fever pitch, with the traditional eight-to-one or four-to-one ratio of GPUs to CPUs moving closer to parity.

EC2 instances make up a large chunk of the modern internet, and they're used in private deployments, as well. Traditionally, AWS engineers have been able to spin up their own instances for development, leveraging the relatively low CPU utilization required for web infrastructure to use more virtual machines. Now, engineers say they're waiting days to get access when they previously could get access within hours. One engineer told The Information that they've never had to wait this long for an instance, even after several years of working at Amazon.

Amazon deploys several different types of CPUs in EC2 instances, including AMD and Intel options and its relatively new Graviton5 chip. Graviton5 is Amazon's most powerful CPU to date, and it uses an Arm-based architecture along the lines of Nvidia's Vera CPU and Arm's own AGI.

The increased demand for CPU comes on the back of AI agents, a new paradigm in productivity that even companies as large as Amazon are struggling to reckon with. Last month, for instance, a coding agent blew through $1.8 million in token costs at Amazon, surpassing a development budget by 860%.

Much of the AI infrastructure currently in place is designed around inference, a workload that's accelerated by GPUs. With the four-to-one ratio, the CPU served as a way to keep the GPUs fed, and nothing more. However, agentic workloads are much more complex. They often involve tool calls that run on the CPU, as well as more complex orchestration of inference on GPUs. This is what has brought CPUs center stage in the agentic era. Intel, AMD, and others have echoed what we've heard from memory and storage companies over the past several months: the demand is so high for CPUs that most companies will take whatever they can get.

The major players are capitalizing on that demand. AMD just recently unveiled its portfolio of Zen 6 'Venice' CPUs for the data center, marking the first time AMD has launched a new architecture in the data center before the client market in decades. Nvidia has also pivoted its messaging away from accelerators and toward its new Vera CPU, vying to stake its claim in an expanding market of agentic AI infrastructure.

Although Amazon is wrestling with CPU capacity across its internal engineers and external customers, The Information reports that shortages are largely a problem for spot instances. A consultant told the outlet that contracted capacity hasn't experienced any shortages.

Following publication, an Amazon Web Services spokesperson reached out with the following statement:

"Demand for AWS services, including EC2, is incredibly strong and growing. Even with this heavy demand, we continue to satisfy the overwhelming majority of compute needs for both our internal and external customers. We work closely with internal teams to meet their compute needs while ensuring they use EC2 resources as efficiently as possible, such as reclaiming idle instances, right-sizing, and scaling up and down as needs change – just as we’ve always done. These efficiencies help manage capacity for internal and external customers alike, and any suggestions that these long-standing efforts reflect new capacity constraints is simply wrong.

This premise is sensationalized. Frugality is in our DNA since Day 1. We have always encouraged our teams to operate efficiently. We also share best practices for how customers can optimize resources to external customers. This isn’t a new directive, and encouraging efficient use of resources isn’t unique to Amazon."

We pressed Amazon on if engineers had been given deadlines to reduce their compute usage, as The Information originally reported. An AWS spokesperson responded: "This narrative on EC2 is inaccurate. As part of our normal business operations, and backed by our leadership principle of frugality, we are always driving efficiency across our resources to ensure teams are optimizing capacity."

AMD's upcoming Zen 6 processors could fix microstutters and improve 1% lows in games — Next-gen CPUs tipped to feature per-core optimizations for thermal and power budgets

AMD is expected to unveil its next-gen Zen 6 platform at CES 2026 with Ryzen 10000 series processors. While we're looking forward to IPC and clock speed improvements, it seems like more subtle, under-the-hood changes could end up upgrading the gaming experience in a big way. According to a tip received by Videocardz, AMD is implementing various per-core optimizations to ensure foreground tasks get priority over background applications. Each new feature is supposed to more smartly manage the power and thermal budgets at the silicon's disposal, so let's go over each of them.

First up, we have CPPC Performance Priority — CPPC stands for Collaborative Processor Performance Control, and it's responsible for communication between the silicon and the OS. It lets the firmware sitting in between decide the performance of each core separately. This feature has actually existed since the Ryzen 3000 series, but it doesn't work perfectly. Zen 6 CPUs are apparently supposed to apply a band-aid fix and improve their effectiveness.

Secondly, we have FloorPerf, which acts as a dynamic, targeted power delivery system. It sets a minimum clock speed for all cores that the silicon can clock down to in case of thermal throttling. For instance, imagine you're running a game in the foreground while Discord and Spotify sit in the background. The temperatures on your Zen 6 CPU rise to the point of throttling, but instead of reducing the speed of all cores, FloorPerf will target the cores running the background tasks first, in order to maintain the performance of your game.

We covered a recent fix like this for the Linux world as well, where a sudden spike in the background can cause the foreground task to choke. Linux has an issue with priority allocation across tasks, so that was a different situation, but similar logic applies here. On a Zen 6 CPU, instead of your game suddenly experiencing microstutters because of aggressive throttling, FloorPerf will try to limit whatever's running in the background first. The aforementioned CPPC Performance Priority should work hand in hand with this feature to maintain clocks on the important cores.

CPPC will get another boost in the form of HighestFreq, which will allow the OS to access more granular chip data to make better core management decisions. As the name suggests, it pertains to maintaining high clock speeds on the cores running a foreground task. The OS will be aware of exactly which core can boost the highest and maintain that speed the longest. This will allow it to assign, for instance, a game's main rendering thread to the fastest cores, while pushing background apps to more power-efficient ones.

In conjunction with this, Zen 6 is also seemingly getting per-core EPP boost. EPP stands for Energy Performance Preference, and it's supposed to fix core parking issues caused by a momentary bottleneck. For example, if the CPU is waiting for the GPU to render the next frame, the clock speeds for the active cores will drop in that moment and struggle to ramp back up in time, forcing all cores to boost when the frame is ready. EPP boost is supposed to identify the active cores and individually keep them in high-performance mode to eliminate any wait times.

Lastly, Zen 6 is reportedly introducing PQOS Global Bandwidth Enforcement and an updated IBS Memory Profiler. Both of these target memory bandwidth with the same goal of maximum stability as everything else discussed so far. The former is responsible for allocating RAM to background tasks, ensuring their usage stays under the limit for foreground priority. The latter will limit L3 cache access to background tasks when it detects that those tasks are slowing down the foreground application, which should help with frametime consistency in games.

As you can tell, all of these optimizations are supposed to work together and harmonize into a more efficient processor at the end — one that maximizes the silicon's potential as much as possible. Of course, none of this is confirmed and there's a lot that could be gated behind product segmentation. We could see some features only on high-end parts, while some are limited to mobile; there's no telling at the moment, but it's exciting stuff, nonetheless. Seems like a battle for the ages is brewing between Nova Lake and Zen 6 next year.

30 years of CPUs at Tom’s Hardware — looking back on three decades of processors, from the Pentium II to Ryzen 9 9950X3D2

31 July 2026 at 16:13

We're celebrating the 30th anniversary of Tom's Hardware. Since the beginning of Tom’s Hardware in 1996, we’ve been covering CPUs. Over the course of the past 30 years, we’ve maintained a comprehensive list of the best CPUs for gaming by reviewing each new release, and we’ve compiled thousands of data points spanning years to compile our CPU benchmark hierarchy. From the Pentium II and the introduction of Dual Data Rate memory to dual 3D V-Cache CPUs, Tom’s Hardware has been there for it all.

It’s time to look back, not just on Tom’s Hardware’s role in the world of CPUs over the past 30 years, but on the broader CPU market. Earth-shattering releases at a given time turned out to be footnotes in hindsight, and bubbling competition that seemed like no real threat turned into seismic shifts in the AMD vs. Intel battle. Hopefully, along the way, we’ll see some reflections of what’s going on in the world of CPUs today.

This is a celebration of 30 years of CPU coverage here at Tom’s Hardware, a history lesson about how the AMD and Intel of yesteryear arrived at the positions they’re in today, and a retrospective of the CPUs that stood the test of time against the refreshes that faded into obscurity just as soon as they were released. We hope you enjoy it.

Like much of the early internet, the true beginnings of Tom’s Hardware (or, rather, Tom’s Hardware Guide) is difficult to pin down, but the earliest archived article concerns the SoftMenu BIOS, which allowed you to change CPU settings through software rather than physical jumper cables; it should go without saying that this article was from July 1, 1996. There were articles before this one, with the original domain of sysdoc.pair.com going online in February 1996.

Tom’s Hardware gained a lot of traction a year later with a CPU review: a look at the Intel Pentium II ‘Klamath’ processor.

Tom’s Hardware’s founder, Thomas Pabst, had discussed CPUs previously, like in a dense CPU guide published the same year, but the Intel Pentium II review marked a turning point. It was published March 1, 1997, more than two months before Intel launched the Pentium II 80522 (or Klamath). It was not positive: “...since I wouldn't eat [Mad Cow Disease] infected beef, I wouldn't be interested in risking an infection of my computer with this CPU either,” wrote Pabst.

The CPU wasn’t officially available, but Pabst was able to test the chip with a pre-release unit shared by two German magazines: C'T Magazin fur Computertechnik and PC Professionell. Following the publication of all three reviews, Intel targeted the two German magazines, threatening to withhold advertising dollars and take legal action against them. Pabst publicized this fiasco and was contacted by The New York Times, which also covered the story. Intel backed down. Pabst later wrote that “...this 'David against Goliath'-incident made Tom's Hardware Guide very famous.”

In the following months, Pabst focused on CPUs quite a bit, breaking from the performance-tuning guides and general enthusiast information the website had previously published. The situation with Intel made Pabst a “secret star,” so much so that AMD not only offered Pabst a free review unit of the upcoming K6, but also apparently offered to cover legal fees should Intel pursue the situation further.

Although the unofficial review of the Pentium II predates it, the first review that looks most like the technical reviews that have been published on Tom’s Hardware for decades came in April 1997 with a review of the AMD K6, a CPU that established AMD as a true competitor to Intel, claiming Pentium II-like speeds for less money.

The performance wasn’t quite on the level of a Pentium II, most notably because the K6 originally arrived at 233 MHz, when 266 MHz was promised. But it was competitive, particularly when compared to the Pentium II 233, and much cheaper. Pabst concluded the review, “All in all I'm sure that this CPU will be very successful… Whoever is contemplating the purchase of an Intel Pentium or Pentium MMX CPU can forget about this now. The AMD K6 is faster and cheaper.”

Later that same month, Pabst published a proper review of the Pentium II, now using finalized silicon. In DOS games and the 32-bit Windows NT, Pentium IIs showed a commanding lead over the K6, though the battle on Windows 95 was closer. “The world is back to normal. Intel’s managers can sleep quietly again. The Pentium II shows that Intel is still the leader in the CPU market,” the review concluded.

A review of the Cyrix/IBM 6x86MX went live in 1997, as well, showing competitive performance with the K6, but much of the rest of the year was focused elsewhere after the Pentium II/K6 showdown. Looking back, it’s interesting to note the dynamic at play between AMD and Intel, with Pabst using a running gag of referring to Intel as the “Empire,” and competitors like AMD and Cynix as “Rebels.” Although Intel backed away from further action on Pentium II, it wouldn’t be the last time Pabst and Intel butted heads.

The Pentium III incident (1999 - 2001)

The Pentium III incident (1999 - 2001)

The competitive performance of K6 brought AMD into focus as the rival to Intel, which Pabst often described as “almost-monopolistic” at the time. However, AMD really put itself on the map with the release of K7, or as it’s better known, Athlon, in June 1999. In our review, we described it as “a milestone in the whole processor scene,” due in part to AMD’s unique three-way instruction decoder, which allows instructions of variable complexity through all three lanes. Intel’s P6 architecture in Pentium III also had a three-way instruction decoder, but they were segmented based on the complexity of the instruction.

We’re still firmly in the single-core era of CPUs here, so an architectural divergence like this, even before testing, represented a goldmine of speed gains. Rather than releasing several variants of silicon sliced up in different ways, as we see with modern CPUs, Intel and AMD refined their chips and released new versions with faster clock speeds. AMD released the Athlon 600 as the fastest chip in the range at 600 MHz first, but less than two months later, it introduced the Athlon 650, and two months after that, the Athlon 700.

Intel was caught off guard and quickly introduced the Pentium III 600 to counter AMD. The original Pentium III range, codenamed Katmai, was largely a refinement of Pentium II ‘Deschutes’ chips; both were built using a 250nm node, in fact. In our original Athlon review, we noted instability with the Pentium III 600, suggesting the architecture couldn’t handle such high clock speeds.

The original ‘Katmai’ range of Pentium IIIs was short-lived, and later in 1999, Intel introduced a new revision called Coppermine. Coppermine introduced an on-chip L2 cache for Intel, and it was built on a 180nm node, allowing Intel to go from 9.5 million transistors on Katmai to 28 million on Coppermine, as well as push clock speeds up to 733 MHz with the initial range, squeezing out a minor increase over the Athlon 700. Less than two months later, AMD introduced Orion, or Athlon Model 2, which also used a 180nm node and clocked up to 750 MHz. This back and forth of minor clock speed improvements is going to stick with us for at least another half of a decade, so strap in.

The goal, of course, was the first 1 GHz CPU, a milestone that AMD claimed for itself in March 2000 with the introduction of the Athlon 1000. Intel had shown a 1 GHz Pentium III, but AMD released a 1 GHz Athlon first. Intel followed shortly after with its first CPU to hit the gigahertz milestone. Intel didn’t want to place second again, so it went to work on the Pentium III 1.13 GHz, which it introduced in July.

Pentium II made Tom’s Hardware a name in the PC industry, but the Pentium III 1.13 GHz gave it a name among enthusiasts. Our review found that the processor wasn’t stable at 1.13 GHz, and less than a month after introducing the chip, Intel recalled it. The Pentium 1.13 GHz would eventually come back in 2001, but at the pace of CPU innovation at the time, even a six-month delay was detrimental.

In June 2000, AMD introduced a refinement of Athlon, codenamed Thunderbird, and days before Intel’s recall, introduced the Athlon 1100. AMD remained uncontested throughout the rest of the year, pushing Thunderbird up to 1.2 GHz. Intel was closing the curtain on Pentium III and trying to move attention away from Athlon toward its upcoming Pentium 4 range.

Intel was struggling to keep pace with Athlon, but work was going on behind the scenes on the new NetBurst microarchitecture, which was set to become the successor to P6. It was introduced to the world with the Willamette core inside the first Pentium 4. Like most major microarchitecture shifts we’ve seen from Intel and AMD, NetBurst wasn’t an immediate success. However, Pabst noted in our review: “I am certain that Intel will deliver very fast Pentium 4 processors very soon. Intel has finally won back the ability to make AMD's life a lot harder.”

Intel pushed P6 down to a 130nm node with the release of Tualatin Pentium III chips, but the focus was on Pentium 4 and optimizing NetBurst. In March, AMD introduced the Athlon 1333, but Team Red was losing steam. Intel had already released a Pentium 4 1.5 GHz, and it introduced the Pentium 4 1.7 GHz (along with a price cut to the range) in April 2001. With a new microarchitecture seemingly bursting with potential, it was only a matter of time before Intel made its way back to the top.

That came in August, when Intel planted its flag on the 2 GHz milestone with Pentium 4, and beat out AMD’s fastest Athlon chip. AMD didn’t like that. Later in the year, in October, AMD introduced its Athlon XP range, and with it came a sneaky switch in marketing strategy. Rather than include the clock speed as part of the processor name (i.e., Athlon 1333), AMD started using model names. No, the Athlon XP 1500+ wasn’t clocked at 1.5 GHz; it was clocked at 1.3 GHz. This nomenclature climbed all the way to the top, with the Athlon XP 2100+, which was not 2.1 GHz, but rather 1.7 GHz.

At the time, AMD described this shift as an alignment with what it was able to deliver with Athlon. During this era, we start to see more significant architecture divergences between Intel and AMD, so much so that like-for-like clocks could result in vastly different performance. That’s what we found in our Athlon XP review, in fact, with the Athlon XP 1800+ (clocked at 1,533 MHz) contesting the Pentium 4 2 GHz. Still, it’s not hard to see what AMD was trying to do. In January 2002, Intel introduced its Northwood core for Pentium 4, which could clock up to 2.2 GHz. AMD wasn’t able to break the 2 GHz barrier yet, but it used product names to suggest it had.

Names weren’t enough. By the middle of 2002, Northwood had picked up steam and could clock as high as 2.8 GHz; even the 2.4 GHz Pentium 4 was able to beat AMD’s fastest Athlon XP 2100+ across our benchmarks. AMD was working on the Thoroughbred revision of Athlon XP, including a node shrink down to 130nm to match Intel’s new Northwood core, which it trickled out through 2002. By the end of the year, AMD had shown the Athlon XP 2800+ as a rival to the Pentium 4 2.8 GHz.

Despite lagging in clocks, AMD had become quite popular during this time due to the competitive performance of Athlon XP and (most importantly) a lower price point than the expensive Pentium 4s. Still, there was a stalemate in technology between Intel and AMD, and Intel would break it in November 2002 with the Pentium 4 3.06 GHz.

It was the first consumer CPU to clock to 3 GHz out of the box, adding another notch to Intel’s belt, but it was also the first CPU to bring Intel’s long-standing simultaneous multithreading implementation, called Hyper-Threading, to market. With higher clocks and two threads to play with, the Pentium 4 3.06 GHz cemented Intel at the top of the performance charts, beating out AMD’s fastest Athlon XP and even a 3.6 GHz Pentium 4 (no Hyper-Threading) in some benchmarks. Tom’s Hardware actually benchmarked the Pentium 4 3.6 GHz nearly a year before it was available, and had data in time to compare to the Pentium 4 3.06 GHz with Hyper-Threading.

More cores, more fun (2004 - 2007)

More cores, more fun (2004 - 2007)

The clock speed battle from the late 90s and early 2000s was starting to fall apart. AMD had demonstrated that performance was more than peak clocks with Athlon XP, and Intel was pushing ahead with Hyper-Threading to get more work done simultaneously each clock cycle. The first half of 2003 was dull in the world of CPUs as Intel worked on its Prescott core and AMD mulled over “ClawHammer,” which would eventually become Athlon 64.

Athlon 64 would be the first to bring AMD’s x86-64 ISA extension (called AMD64) to the desktop market (it previously showed up in Opteron). It rolled out in September 2003, and just a week before release, Intel launched the Pentium 4 Extreme Edition, which was widely considered a panic switch in response to Athlon 64 while Prescott was still under wraps. Although Intel maintained the performance crown with P4 Extreme against the Athlon 64 FX-51, it did so at a much higher price.

Still, this late-stage battle as Intel and AMD moved toward a 90nm node was important. Intel started marketing expensive, high-performance processors directly to enthusiasts in a market that would eventually get the HEDT, or high-end desktop, name. Meanwhile, AMD designated some Athlon XP chips with the FX name, which signaled high-performance chips with unlocked multipliers.

Intel was first to get down to 90nm with its highly anticipated Prescott core, though it arrived with a whimper. It clocked slower, allowing the FX-51 to remain competitive and Northwood chips to remain at the top of the charts in our review. There, our reviewer Patrick Schmid wrote: “In our opinion, Intel today does not care about Prescott as a processor, but as a marketing instrument. It is fast enough, which is mainly what counts, and since the 90 nm production process yields cheap processors in vast quantities, the Santa Clara-based company gains new flexibility.”

AMD made it down to 90nm later in the year with the FX-55. The FX-55 allowed AMD to close the gap with higher-clocked Pentium 4s, as we found in our review. However, it was becoming clear that the chase for higher clocks wouldn’t be enough. In our review, Schmid wrote in 2004: “Today, the performance gap between the fastest and the slowest processors in our benchmark charts is rather small.”

Intel fired back at the beginning of 2005 with Prescott 2M, a minor revision to the Prescott core with 64-bit ISA extensions, and released the Pentium 4 Extreme Edition 3.73. The tide shift came in the summer of 2005 when AMD launched the Athlon 64 X2, built on a 90nm node, and featuring two cores on the same package.

Intel had released its double-core Pentium D just weeks earlier, which was also a dual-core chip, but the design forced Intel to compromise clock speeds — an important spec given how few applications could actually leverage a dual-core chip in consumer software. AMD ultimately won the battle with the Athlon 64 X2, largely due to the fact that it could keep pace with single-core Athlons in most benchmarks, as you can see in our early preview of the chip.

AMD released more Athlon 64 X2 chips throughout 2005, while Intel rolled out various chips under different Pentium brands, including the Smithfield core on Pentium D. Intel built out the range into 2006, using another node shrink down to 65nm with the Presler core, which was the final revision under the Pentium brand. In January 2006, Tom’s Hardware first reported that Intel planned to drop the Pentium brand, a name that it had kept for over a decade.

In its place? The new Core microarchitecture, finally moving on from NetBurst, which had been plagued with thermal issues as clocks climbed. Built out of Intel’s work in mobile chips, the Core 2 Duo was Intel’s first proper dual-core processor — the “double-core” Pentium D was just two Pentium dies fused together. It was a tide shift.

As we found in our Core 2 Duo review, the base E6600 and E6700 often beat, or at least matched, AMD’s Athlon 64 FX-62, while the supercharged Core 2 Extreme X6800 established a new performance tier at the high-end. Further, it did so at reasonable power levels, finally taking the efficiency fight back to AMD.

Intel doubled down, literally, with the Core 2 Extreme QX6700 at the end of 2006. Although Intel had introduced a four-thread processor previously, the Core 2 Extreme QX6700 was the first CPU with four cores to hit the market. It took two dual-core dies from Core 2 Duo and put them together on a single package. AMD brute-forced a quad-core with the 4x4 platform and dual Athlon 64 FX-70 chips, but there was a major tradeoff in cost, thermals, and power demands.

The coast of Nehalem (2007 - 2010)

The coast of Nehalem (2007 - 2010)

For the first time in the early aughts, Intel was firmly in the driver’s seat for enthusiasts. AMD drummed up some interest with its dual-chip Athlon 64 systems, and it finally moved down to a 65nm node at the start of 2007. But Intel was on a tear, and it would continue its momentum for years to come.

That started by formalizing the success of the Core microarchitecture. Instead of squeezing everything out of a microarchitecture for several generations, as it had done with P6 and NetBurst, Intel transitioned to its well-known tick-tock cycle. First, there’s a node shrink on its existing architecture, then there’s a new microarchitecture on that node, and the cycle continues. Core was the tock at 65nm, and it would move down to Penryn revision at 45nm later in 2007.

AMD struggled to keep pace. After introducing its AM2 socket in 2006, it continued refining the Athlon 64 X2 lineup with a new 65nm node, but Intel was firmly in the lead, forcing AMD to slash prices and settle into the market as a budget-focused alternative to the shiny Core 2 Duos. AMD doubled down in this area with its K8 microarchitecture, releasing a series of efficient “BE” series chips throughout the back half of 2007, which we found were excellent for efficiency and price-to-performance in our review.

Team Red had its chips on K10, and specifically, the new Phenom brand that it made noise about throughout 2006 and 2007. The Phenom X4 series launched in November, featuring the first true quad-core design; that is, using a monolithic die as opposed to MCM like Intel’s Core 2 Quad. Unlike Intel’s Core 2 Extreme, which was reserved for only the most entrenched enthusiasts, AMD targeted midrange builders.

In our Phenom 9700 review, we found that Intel still maintained the performance crown, but AMD offered a cheaper quad-core and offered identical price-to-performance at release. Further, AMD offered support for the chips on both the AM2 socket and the new AM2+ socket, starting a trend of socket longevity that we can still see in action today. With cheaper quad-core CPUs and less upgrade cost, AMD focused less on battling Intel at the high-end and more on delivering in the midrange.

Intel continued to release more Core 2 Duo and Core 2 Quad models throughout 2008, but behind the scenes, it was working on its next major architectural shift: Nehalem. AMD built out its Phenom line, meanwhile, introducing a tri-core variant, as well as several “Black Edition” models that featured peak clocks and unlocked multipliers for enthusiasts, likely in a bid to grab some attention from Intel’s Extreme lineup.

Nealem came onto the scene in late 2008 in the form of Bloomfield chips. They required an entirely new platform and DDR3 memory, but also promised entirely new performance benefits. Intel managed to create a true quad-core chip with Bloomfield, and one that enthusiasts could actually afford, with the range going down as low as $280. Further, it reintroduced Hyper-Threading after ditching the technology during the early dual-core days, giving enthusiasts eight threads to play with.

The spread between Intel and AMD grew wider. In our review of the Core i7-965 Extreme, we found it was 64% faster than AMD’s fastest chip at the time. Despite offering compelling products at competitive prices, AMD was falling further behind. Intel was far ahead; it had a die shrink ahead, and the legendary Sandy Bridge microarchitecture was waiting in the wings to pick up the tick-tock cycle once again.

AMD bit back in early 2009 with Phenom II (along with Athlon II), finally moving down to 45nm. It brought Team Red back up in the rankings, but Bloomfield still held onto top-end performance. In our original Phemon II review, we found that Intel was about 22% ahead of AMD at the high-end, but AMD offered compelling performance given the platform costs. Sounds familiar.

With tight integration of design and manufacturing under one roof, Intel was moving faster than AMD on process improvements, allowing it to keep a consistent lead in performance, particularly at the high-end. Intel had its Lynnfield chips at 45nm, as well as Clarkdale chips at 32nm, but the 32nm successor to Bloomfield came in early 2010, known as Gulftown. And with Gulftown, Intel could claim a multi-core milestone on a monolithic die for the first time with the six-core Core i7-980X.

At $1,000, the Core i7-980X still only appealed to a small number of enthusiasts. AMD helped fill the gap later in the year with the Phenom X6 launch, introducing six-core models of its own. AMD couldn’t match the 980X at the high-end, but Phenom represented an affordable entry-point to six-core chips if you ran heavily-threaded workloads, as we noted in our review. Still, Phenom X6 was AMD trying to keep pace with Intel. Behind the scenes, AMD was working on a new microarchitecture called Bulldozer, which was built from the ground up for a new generation of chips and finally allowed AMD to move down to 32nm.

It’s easy to pick on Bulldozer in hindsight, but leading up to release, the anticipation was palpable. K8 was a smash success, and K10 built on that success, but Bulldozer was built from the ground up, presumably for the position AMD had found itself in the market. Nearly a year before Bulldozer showed up on the market, however, Intel introduced an architecture that still resonates among enthusiasts today — Sandy Bridge.

Intel unified its product stack with Sandy Bridge and set much of the foundation for the company’s releases through Raptor Lake Refresh. Instead of two broad ranges, Intel placed most of the Sandy Bridge lineup on a single socket. It also brought integrated graphics to all the chips in the lineup, at least in the initial range (some later releases cut the iGPU), as well as unlocked the multiplier on some non-Extreme SKUs to compete with AMD’s unlocked Black Edition chips.

It was a smash success. Reviewing four Sandy Bridge chips, our reviewer Chris Angelini wrote: “Existing Lynnfield- and Clarkdale-based processors already offer strong performance compared to AMD’s lineup. Significant gains, clock-for-clock, compound in the face of notable frequency increases across the board (thanks to a mature 32 nm process), giving Sandy Bridge an even more commanding position.”

Raw performance improvements are one thing, but Sandy Bridge was attractive for several other reasons, as well. Overclocking still represented a solid performance boost in this era, and Intel was offering overclocking capabilities at mainstream price points alongside chart-topping performance out of the box. They also introduced Quick Sync to accelerate video encode/decode, and although we have video encode/decode acceleration in modern GPUs, Quick Sync still serves as a fundamental feature for video editing and media servers.

AMD’s response was Bulldozer, which was rumored ahead of release to outperform Intel’s Core i7-950 by upwards of 50%, as well as introduce a true eight-core chip to the consumer market for the first time. If that wasn’t enough, prior to release, the flagship FX-8150 set a world record for clock speed, peaking at 8.429 GHz. AMD would be the first to release a consumer CPU with eight cores, but just about every other aspect of Bulldozer was problematic.

Achieving eight cores in a single package came with significant trade-offs. Up to this point, AMD hadn’t used any form of simultaneous multithreading, but it implemented a version of SMT in Bulldozer. Unlike Intel’s traditional SMT implementation, Bulldozer used two integer units on a core, but shared floating point resources. The major trade-off was how small the integer execution clusters were in order to save space. AMD designed an architecture for a world of heavily-threaded software that just didn’t exist at the time, and it traded very important single-core speeds to achieve that design.

The flagship FX-8150 was marketed as an eight-core chip, with the eight-core count coming from AMD’s odd SMT implementation. Although there were two integer execution units per “module,” as AMD calls them, the floating point unit was shared. This discrepancy was actually the focal point of a 2015 lawsuit, which AMD settled in 2019 to the tune of over $12 million.

(Image credit: Tom's Hardware)

It was a flop. Angelini sums up the issue nicely in his October 2011 review of the FX-8150: “[Intel doesn’t] have to do anything at all. Its nearly year-old 95 W parts fend for themselves without even a price adjustment.” Intel had new chips of its own, as well. Just six months later, it introduced Ivy Bridge, taking the solid foundation of Sandy Bridge and moving it down to a 22nm node.

Ivy Bridge wasn’t a big hit on desktop, but it didn’t need to be, given the advantage Intel had already established with Sandy Bridge. Improvements were in the single digits, as we noted in our Core i7-3770K review, but Ivy Bridge brought improvements to integrated graphics to fight against AMD’s burgeoning lineup of APUs and thermal improvements targeting small form factor devices — especially laptops in a new category of “ultrabooks” that Intel was targeting.

12 months after the FX-8150 was introduced, AMD released a revision of the Bulldozer architecture named Piledriver. It promised better IPC and higher clock speeds, which was compelling, as AMD’s FX-4170 released earlier in the year as the first CPU to hit 4 GHz out of the box. Piledriver had a test run earlier in the year through AMD’s Trinity APUs, as well, showing around a 15% improvement compared to Bulldozer.

The flagship Piledriver, the FX-8350, was indeed better than its Bulldozer predecessor, but it was clear the underlying architecture had issues that wouldn’t allow AMD to scale up. AMD’s flagship was only competitive with Intel’s Core i5 options, and power use, although tamed in Piledriver, still meant the chip ran hot. It was immediately forced into a price cut upon release. After two failures to launch flagships, Intel effectively owned the high-end, which it continued to dominate with CPUs like the Core i7-3970X.

Around six months after Piledriver chips shipped, AMD released another two chips, both running at an insane 220W TDP and shipping with their own liquid cooling system. The highest-end offering, the FX-9590, was the first CPU to hit 5 GHz out of the box. AMD had learned the hard way what it had preached back in the Athlon XP days — clock speed isn’t everything.

The dawn of 14nm (2014 - 2016)

The dawn of 14nm (2014 - 2016)

With a 22nm product shipped, Intel went back to a tock and came out the other side with Haswell. Today, Haswell is heralded as a legendary architecture; we’ve all seen forum comments about gaming with a Core i7-4770K more than a decade after it was released. At the time, however, it established a narrative that would follow Intel for the next several years. That narrative being that Intel ships a new generation of quad-cores, each year, with minor IPC improvements and not much more. That’s certainly the impression Angelini came away with after reviewing the Core i7-4770K.

30 years of CPUs at Tom’s Hardware

(Image credit: Tom's Hardware)

Intel didn’t have to move the needle beyond that point. Although AMD had shipped Bulldozer and Piledriver, a lot of turmoil was going on behind the scenes. Two further revisions of Bulldozer, Steamroller, and Excavator were planned, but AMD largely canceled the two revisions outside of a few low-end products. During this time, AMD underwent a series of sweeping layoffs and executive changes, cutting thousands of employees. Looking back at the time through a modern lens, some long-time AMD employees say that the company would’ve faced bankruptcy had it not been for semi-custom partnerships with Microsoft and Sony for their game consoles.

From the release of Piledriver in late 2012 through 2017, AMD didn’t release a ton of new CPUs. It released some revisions of Piledriver chips like the FX-8370, but we didn’t see any new microarchitecture. And planned node shrinks with Steamroller and Excavator were canned, with only a handful of desktop CPUs surviving, which were repurposed as low-end Athlon X4 CPUs years later. Intel had won.

It didn’t immediately rest on its laurels, however. Hearing the criticism of Haswell for desktop enthusiasts, Intel introduced the Core i7-4790K alongside other ‘Devil’s Canyon’ chips in mid-2014 as it worked on another tick behind the scenes down to 14nm. The result, which arrived almost a year to the day after Devil’s Canyon, was Broadwell. The Broadwell-H range — not Broadwell-E, which shows up later — isn’t very big and didn’t have much for enthusiasts. But Broadwell got Intel down to 14nm, and it would stay there until the release of Alder Lake CPUs in 2021.

We didn’t know that at the time, though. Broadwell laid the 14nm foundation for Skylake, which came hot on the heels of Broadwell-H after that architecture experienced a series of delays. Intel’s first true eight-core chip, the Core i7-5960X from the Haswell-E range, still gave the HEDT market what they were looking for, but Skylake was pushing ahead in the mainstream. In early performance testing, we said Skylake was the first architecture “to really get enthusiasts excited since Sandy Bridge.”

Intel didn’t need to rush at the time, so it didn’t. There wasn’t an Athlon 64 breathing down Team Blue’s neck. A year later, in 2016, Intel launched Broadwell-E for HEDT, marking the first-ever 10-core desktop CPU with the Core i7-6950X. It wasn’t a massive leap forward over Haswell-E, but Intel was competing with itself. “Intel’s clearly the prettiest girl in the room, is well aware of this fact and, based on Broadwell-E's pricing, doesn't need to beat the ‘value’ of last generation's -Es by much,” our reviewer Igor Wallossek wrote in his Broadwell-E review.

Although Intel was a clear market leader, it was slowing down significantly. Earlier in 2016, it quietly revised its tick-tock cycle, moving to a tick-tock-tock cadence where we’d see a new process followed by a new microarchitecture followed by an optimization of that architecture. Intel wasn’t juiced up with Moore’s Law like it was in the early aughts, but it competed in a category of one. What were you going to do? Buy AMD?

Feeling Zen (2017 - 2020)

Feeling Zen (2017 - 2020)

Shortly after the ball dropped into 2017, Intel released its Kaby Lake range of CPUs, now sporting the “14nm+” process and serving as the first optimization pass in Intel’s new release cadence. It was fine. The range came with a clock speed bump over Skylake, but otherwise, Intel released the same architecture sporting nearly identical specs, from core counts to cache sizes.

Behind the scenes, trouble was brewing. Six months before Kaby Lake made its way to market, AMD detailed its first entirely new microarchitecture since Bulldozer, named Zen. In addition to promising a 40% improvement in IPC over Excavator, the Zen platform would come with support for DDR4 and finally move AMD down to a 14nm node. For the architecture itself, AMD implemented SMT, completely redesigned its cache hierarchy, and added a micro-op cache to aid an updated branch predictor.

Two months after Kaby Lake rolled out, AMD launched the Ryzen 7 1800X. The revolution didn’t happen in a day. In our Ryzen 7 1800X review, reviewer Paul Alcorn (now Tom’s Hardware editor-in-chief) wrote: “AMD's Ryzen 7 launch represents more than just a new CPU family. For most of our readers, it signals the return of competition to the enthusiast-oriented processor market. And considering the flagship 1800X’s potent cost advantage compared to Intel's Core i7-6900K… Ryzen 7 does deliver. It's just not as universally superior as the company wanted everyone to believe.”

AMD still had quite the year ahead. A month later, the Ryzen 5 1600X launched with performance that could rival Broadwell-E, just for a much cheaper price. And by Summer, the Ryzen 3 1300X proved you didn’t need an expensive CPU and motherboard to get into overclocking. AMD capped its Ryzen rollout with Threadripper, scaling up the Zen microarchitecture to massive core arrays and finally bringing something to the HEDT market — a market that Intel had almost wholly owned since the Pentium 4 days.

Still, Zen had shortcomings, particularly in games, where just about any quad-core from Intel still ruled the roost. AMD was competitive, but Intel was still firmly in the driver’s seat. It barely reacted to the Ryzen onslaught over the summer, rolling out its high-end Skylake-X and Kaby Lake-X HEDT offerings throughout the back half of 2017. Even then, however, problems started emerging.

Kaby Lake-X was effectively a rerelease of Kaby Lake with a bit of extra headroom, but restricted to the expensive X299 platform. It was discontinued less than a year after release. Skylake-X was Intel’s true next-gen HEDT offering, signaled by the first use of “Core i9” in front of its flagship SKU. It performed like an Extreme Edition, and it was priced like one too, despite an issue in thermal dissipation that we uncovered in our Core i9-7900X review. Meanwhile, AMD was rapid-firing firmware and chipset updates for its small Ryzen range, and fixing several issues that came up in reviews in the process.

Less than a year after Kaby Lake launched, Intel released Coffee Lake, which was yet another Skylake revision built on 14nm, but this time with extra cores in tow. As you can read in our Core i7-8700K review, Coffee Lake did what Intel wanted it to do, shoring up the fight in heavily-threaded productivity applications against AMD while maintaining leadership in games. Still, AMD was making headway. By the end of 2017, estimates suggest AMD took back anywhere from 2% to 12% market share from Intel, with the higher end of the spectrum coming mainly from the DIY PC market. That’s no small feat for a company that was dead in the water with CPUs 12 months earlier.

Back on more even footing, the next goal post was a node shrink. Intel was gunning for 10nm, which is a milestone it failed to meet with both Kaby Lake and Coffee Lake. AMD, as a fabless designer, was at the mercy of its then-partner GlobalFoundries for the next node shrink. AMD struck first with Ryzen 2000 in early 2018, built on GlobalFoundries 12LP node, which was a revision of the 14LP (14nm) node used in the original Zen. Fittingly, AMD called it Zen+.

Debuting the architecture was the Ryzen 7 2700X, which was an iterative update. However, it helped reacquaint the market with the progress AMD had made. Zen+ came with higher frequencies and reduced memory latency, and all of the software adjustments AMD had made after the original Zen launch. And the range seemed specifically designed to undermine Intel, offering overclocking support across the full stack (and with B-series chipsets), and bundling a surprisingly decent cooler in the box.

Intel still held the edge in gaming, but the margins were narrowing, especially with a bit of overclocking thrown into the mix. Intel was feeling the heat, due in no small part to its continued issues moving down to 10nm. It responded in late 2018 with Coffee Lake Refresh, bringing the Core i9 branding into its main lineup for the first time with the Core i9-9900K and offering an eight-core, 16-thread chip. The strategy, it seems, was to push out AMD at the high-end, as Ryzen 7 was closing in on Core i7.

It worked. Intel had the fastest gaming processor on the market, and even the Core i7-9700K managed to push Intel’s lead in the Ryzen 7 battle higher. These marginal updates were buying time for AMD and Intel. Both companies clearly understood that whoever could go below 14nm first would have a massive advantage, and likely define an entirely new market dynamic.

AMD claimed that advantage for itself with the introduction of Zen 2 in mid-2019. Bolstered by TSMC’s 7nm node, AMD pushed out the Ryzen 9 3900X, moving beyond eight cores to AMD’s first 12-core consumer design. Intel held a slight edge in gaming through Coffee Lake Refresh, as you can read in our Ryzen 7 3800X review, but that delta was becoming less important as AMD took the lead in heavily-threaded workloads.

Later in the year, AMD rolled out the Ryzen 9 3950X, the first 16-core desktop processor ever. It was a bloodbath. Less than a year earlier, Intel had introduced its Skylake-X HEDT platform, including the Core i9-9980XE priced at $2,000. Now, at stock settings, the $750 Ryzen 9 3950X offered better multithreaded performance, along with competitive single-threaded and gaming performance. And you didn’t need to shell out for Intel’s expensive HEDT platform. And you could unlock PCIe 4.0, whereas Skylake-X (and even the following Cascade Lake-X) were locked to PCIe 3.0. You don’t spend top dollar on an HEDT platform for last-gen connectivity.

Intel was getting pushed into a corner, and it followed up less than six months later with Comet Lake to stave off AMD’s Ryzen onslaught. The flagship Core i9-10900K allowed Intel to maintain the lead in gaming, but now, AMD was in a clear lead in applications with the Ryzen 9 3950X.

Reviewing the Core i9-10900K, Alcorn wrote: “The Core i9-10900K is exactly what we would expect from an overclocked 10-core 14nm Skylake derivative: Exceptional performance in gaming and lightly-threaded workloads, competitive performance in multi-threaded work, and downright ugly power consumption and thermal output. And that's pretty much what you get with the Core i9-10900K – an overclocked 14nm processor right out of the box.”

AMD didn’t let up. It moved onto Zen 3 later in the year, launching its 16-core Ryzen 9 5950X alongside the main range in late 2020. And with its fourth Ryzen salvo launched, the battle was over. Opening our Ryzen 9 5950X review, Alcorn wrote, “With the Ryzen 5000 series, it's fair to say that AMD has finally, and fully, eclipsed Intel's performance dominance in desktop PCs.” It was a clean sweep, with AMD taking the lead in gaming, multithreaded, and single-threaded performance. Three years and four CPU generations later, AMD was back on top.

Forging a new path (2021 - 2024)

Forging a new path (2021 - 2024)

In the years leading up to 2021, it had become clear that a tick-tock, or even a tick-tock-tock, wasn’t possible any longer. Process shrinks were arriving later, and a pesky little pandemic threw the tight supply chain required for chip manufacturing into a frenzy. Both AMD and Intel knew they needed a different approach, but that would manifest in wildly different ways.

Intel was all-in on a hybrid architecture, using a mixture of microarchitectures on a single package to bolster core counts, similar to Arm-based designs. Intel talked a lot about Alder Lake leading into 2021, overshadowing its own launch of 11th-Gen Rocket Lake chips. The flagship Core i9-11900K was a massive disappointment, carrying all of the issues of the previous-gen Core i9-10900K while packing two fewer cores. Yes, Intel actually cut two cores from its flagship.

It seems Intel knew the issues with Rocket Lake. The chips launched with little to no fanfare, and as opposed to a gradual rollout like we see with most CPU generations, Intel blasted every model of Rocket Lake onto the market, knowing full well that Alder Lake chips would take their place eight months later. AMD, with renewed confidence, slowly built out the Zen 3 lineup with new APUs and variations of Ryzen 5000 as it worked on its next-gen Zen 4 architecture.

In late 2021, Intel swept Rocket Lake under the rug with the release of Alder Lake. Intel had finally moved on from 14nm with Intel 7 (10nm), and it was mostly successful. Intel reclaimed top placements in gaming, multithreaded, and single-threaded performance, and although the margins were thin, Alder Lake made it clear that Intel wouldn’t go quietly. “The Alder Lake processors mark a massive generational leap forward for Intel in nearly all facets, including gaming, performance in lightly- and heavily-threaded work, power consumption, overclocking, and platform connectivity options,” wrote Alcorn in our Core i9-12900K review.

AMD was working on something unique of its own, however. Zen 4 was in the oven, and it was clear there would be a competitive battle with Alder Lake. But before Zen 4 arrived, AMD introduced the Ryzen 7 5800X3D. It was the first processor with AMD’s 3D V-Cache packaging, and at the time, it looked like a slightly-tuned processor targeting gamers, with somewhere in the range of a 10% to 15% uplift in gaming performance specifically. In a surprising turn, the speculation actually undersold just how big of a deal the Ryzen 7 5800X3D would become.

Six months after the release of the Core i9-12900K, AMD was back on top of the gaming charts with the Ryzen 7 5800X3D, no less sporting a last-gen architecture and an SRAM stacking technique that limited boost clocks and locked the multiplier down. It outran the Core i9-12900K by nearly 10% in games while costing hundreds less, and it was nearly 30% faster than a stock Ryzen 7 5800X, as you can see in our Ryzen 7 5800X3D review.

Intel would come back with Raptor Lake in late 2022, but the Ryzen 7 5800X3D established a new category of true gaming CPUs that traded some application performance for peak frame rates. And that’s a category of chips that even today Intel hasn’t managed to crack.

AMD came first, however, launching Zen 4 in September 2022. The flagship Ryzen 9 7950X managed to leapfrog the Core i9-12900K, as you can see in our Ryzen 9 7950X review, but not by much, and the Ryzen 7 5800X3D remained at the top of the gaming charts. Immediately, speculation around 3D V-Cache chips for Zen 4 went into motion. Also tampering the Zen 4 release was an entirely new platform, which required costly DDR5 memory.

Intel capitalized with Raptor Lake mere weeks later. The flagship Core i9-13900K was back on top across tests, even managing to outclass the Ryzen 7 5800X3D in games. For the first time since the heyday of Athlon, we had a hotly competitive CPU market with AMD and Intel leapfrogging each other with each new release. Still, there was a niche that wasn’t being filled. 3D V-Cache disrupted the status quo for gaming processors, but it came with a significant trade-off to application performance. The stage was set for a CPU that could offer the best of both worlds.

AMD delivered that in early 2023 with the Ryzen 9 7950X3D and (to a much lesser degree) Ryzen 9 7900X3D. A couple months before, Intel cracked the 6 GHz barrier out of the box with the Core i9-13900KS, but AMD was offering something more compelling than peak clocks. The Ryzen 9 7950X3D managed to outclass Intel in multithreaded and single-threaded performance, all while offering a double-digit jump in gaming performance thanks to 3D V-Cache.

Raptor Lake saw a refresh later in 2023, and although the flagship was able to close the application performance gap in our Core i9-14900K review, AMD still held a firm grip on gaming performance, especially with the trimmed-down and relatively affordable Ryzen 7 7800X3D. AMD had taken the lead, but Intel, finally, executed its tick-tock-tock strategy and set its eyes on a radically new architecture in the form of Arrow Lake.

Reckoning with the real world (2024 - today)

Reckoning with the real world (2024 - today)

Under AMD’s thumb and clearly behind in pace, Intel needed to innovate. The result was Arrow Lake. Like Bulldozer, it’s easy to write Arrow Lake off in hindsight, especially given how recent it is. As you can read in our Core Ultra 9 285K review, Arrow Lake chips only marginally improved in application performance over their 14th-Gen counterparts, and they were actually slower across most games. But, architecturally, Arrow Lake is as big a swing as Bulldozer was.

For the first time, Intel outsourced manufacturing to TSMC, clearly behind the Taiwanese manufacturer for cutting-edge nodes. It disabled Hyper-Threading, killing off a staple of Intel CPUs for decades, and it doubled down on Intel’s hybrid architecture. Those bets didn’t pay off, but they were big bets for a company struggling to reckon with a reinvigorated AMD.

AMD followed up Zen 4, predictably, with Zen 5 in mid-2024, shortly before the Arrow Lake release. With Arrow Lakes' struggles, it’s easy to forget the problems Zen 5 had at launch, and the relatively small generational uplift it offers even today. AMD has continued to build out this lineup with X3D chips, and it finally delivered 3D V-Cache on both CCDs with the Ryzen 9 9950X3D2. But going back to our Ryzen 9 9950X review, Zen 5, at its core, isn’t the massive uplift we had become accustomed to in the early days of Zen.

Intel tried to give Arrow Lake a bit more life with a small refresh earlier this year in the form of the Core Ultra 7 270K Plus and Core Ultra 5 250K Plus, and those CPUs set the stage for the next era of CPUs. They put Intel into the position AMD found itself during the Bulldozer/Steamroller days, clearancing off silicon to maintain a competitive position in the market.

That’s where we are today, with our sights set on Zen 6 and Nova Lake. But there are some realities in the PC enthusiast space that we have to contend with today. DRAM pricing is out of control, and showing no signs of slowing down, and a sudden boost in demand for CPUs for agentic AI means consumer chips have taken a backseat. Zen 6 and Nova Lake were both expected by the end of the year; it’s looking more likely that they’ll slip into 2027.

History doesn’t repeat, but it often rhymes, and we can see traces of days past over the last 30 years start to creep into the dynamics today. Today, we see a defiant AMD and an Intel that seems ready to get scrappy in order to earn back market share. Will it pay off? We don’t know, but Tom’s Hardware will be here to cover whatever comes next in the world of CPUs, just as we’ve been for the past 30 years.

Users cry foul after AMD stripped memory crypto from its consumer CPUs

15 June 2026 at 18:55

A decade ago, AMD added a protection to its high-end CPUs to protect them against cold boot attacks and other types of physical exploits that siphon sensitive data out of the connected memory chips. Short for Transparent Secure Memory Encryption, TSME encrypts the entire contents stored in memory, making the data useless to physical attackers.

Over time, AMD added TSME to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version. Over the years, users of these lower-end chips have gotten used to the added security. Recently and without warning or notice, this lower-end line of AMD chips suddenly dropped the protection, and did so in a way that was impossible to detect on Windows machines and required a fair amount of technical work when using Linux.

Now you see it, now you don't

AMD has yet to say why TSME worked on these CPUs, or even to confirm the change. AMD declined to answer questions sent by email other than to say TSME "is a security feature only applied to PRO CPUs as part of AMD PRO Technologies." The statement is the first known time the chipmaker has explicitly made this restriction public.
