CPU Benchmarks and Hierarchy 2021: Intel and AMD Processors Ranked

Our CPU benchmark performance hierarchy ranks all the current and previous generation Intel and AMD processors, including all of the Best CPUs for Gaming, based on performance. Your CPU has a huge effect on overall performance and, to many, is a computer's most important component. CPU benchmarks help us suss out the differences, but when it comes time to buy a CPU for your desktop, you'll find a dizzying collection of model numbers and specs from both Intel and AMD. 

We've listed the best CPUs for gaming and best processors for work in other articles, but if you want to know how each chip stacks up against all the others and how we come to our decisions, this CPU benchmark hierarchy is for you. We also recently added a new article covering the CPU benchmark hierarchy for Cyberpunk 2077, a dedicated piece to show performance scaling in the most hotly-anticipated game in recent history.           

We recently added the Ryzen 5 5600X, Ryzen 9 5950X, 5900X, and Ryzen 7 5800X to our rankings, along with all of the previous-gen Zen 3, Zen+, and Zen 1 versions of those chips. The new Ryzen 5000 processors represent a watershed moment for AMD: The company has swept our CPU benchmark hierarchy and taken the lead in every metric, including our gaming, single-threaded, and multi-threaded categories. Intel is firing back, though, with its upcoming 11th-generation Rocket Lake-S CPUs that the company says will take the gaming performance crown. 

We also recently added AMD's Threadripper Pro 3995WX to our CPU benchmark rankings. This fire-breathing chip comes armed with 64 cores, 128 threads, and eight memory channels that support up to 2TB of memory. 

We'll explain how we ranked the processors under each table. The game testing ranking is first. We also include an application performance metric in our application score tables, which we've split up into single- and multi-core measurements (below gaming table).

The most powerful chip gets a 100, and all others are scored relative to it. If you want our recommendations for specific price bands, please check out our Best CPUs for gaming page.   

We are busy retesting our full arsenal of processors with a newer version of Windows 10 to measure performance for our CPU benchmarks. As such, chips without a score are ranked according to their previous rankings with our older CPU benchmark test suite. We'll add specific measurements for those chips as our CPU benchmark testing continues. 

CPU Benchmarks and Performance Hierarchy Charts

We rank all the Intel and AMD processors in the tables below, but we don't include overclocked performance or 99th percentile fps rankings. You can see all of those numbers in the charts above. Bear in mind that the charts above use the raw performance numbers, whereas our CPU benchmark rankings below use a score to rank the chips relative to one another. This group of results also comprises only the chips that have passed through our newest test suite, while the tables below include rankings based on past CPU benchmarks. Finally, the pricing in the charts above represents MSRPs. Given the current state of chip shortages, you likely won't find many of these chips at these prices at retail.

We've ranked all the consumer Intel 10th, 9th, 8th, and 7th Gen processors, along with AMD's Ryzen and Threadripper chips from all four generations. We have two rankings for each chip, based on 1080p and 1440p CPU gaming benchmarks, but the chart is aligned sequentially based on the 1080p game results. The 1440p listings aren't listed in sequential order due to unfortunate limitations with our tables. Pay attention to the 1440p rankings: Some faster chips at 1440p CPU benchmarks may be listed below slower chips simply because of the 1080p results. 

We measured performance for the 1080p CPU gaming benchmarks with a geometric mean of Borderlands 3, Hitman 2, Project CARS 3, Red Dead Redemption 2, Shadow of the Tomb Raider, and The Division 2. 

We measured performance for the 1440p CPU gaming benchmarks with a geometric mean of Borderlands 3, Project CARS 3, Red Dead Redemption 2, Shadow of the Tomb Raider, and The Division 2.  

As you can see, AMD's Ryzen 9 5950X and Ryzen 9 5900X take a healthy lead over Intel's flagship Core i9-10900K in both 1080p and 1440p results, and as you'll see in our Ryzen 9 5950X and 5900X review, overclocking doesn't even the score for Intel. 

AMD's stock Ryzen processors beat the overclocked Intel processors, which is quite the feat, and Ryzen is even faster after overclocking, too. Also, check out those CPU benchmark performance deltas between the previous-gen Ryzen processors and the 5000 series. That's impressive.

Most folks overlook the incredible power efficiency of the Zen 3 processors, but that equates to a faster, cooler, and quieter system that doesn't require super-expensive cooling solutions. Take note of the TDP divide in our charts - it's surprising. Check out our review for more in-depth power testing.     

Intel and AMD Single-Threaded CPU Benchmark Performance Hierarchy

We calculate the above single-threaded CPU benchmark rankings based on a geometric mean of y-cruncher, Cinebench, POV-Ray, and LAME. The latter consists of two tests: One short duration test and one extended-duration test to measure performance once Intel's boost duration limits have been exceeded. 

Single-threaded performance is often tied directly to the responsiveness and snappiness of your PC in any number of daily applications, like loading an operating system or surfing the web. This metric largely depends upon a mixture of instruction per cycle (IPC) throughput (the number of operations the chip can execute in one clock cycle) and frequency, which is the speed at which the transistors switch between on and off states. 

However, a whole host of other considerations, such as cache, architecture, and interconnects (like rings, meshes, and infinity fabric) impact this measure of per-core performance, so these results do not align perfectly based upon clock frequency. Instead, performance varies with each application and how well it is tuned for the respective architectures.  

With all that said, the CPU benchmark delta between Intel's flagship Core i9-10900K and the Ryzen 5000 processors is incredible - at worst, Ryzen 5000 is 10% faster in single-threaded performance.

Intel and AMD Multi-Threaded CPU Benchmark Performance

The multi-threaded workload column is based on CPU benchmark performance in Cinebench, POV-ray, vray, Blender (four tests - Koro, Barcellona, Classroom, bmw27), y-cruncher, and Handbrake x264 and x265 workloads. These CPU benchmarks represent performance in productivity-focused applications that tend to require more compute horsepower.

Like we see with single-threaded performance metrics, multi-threaded performance, which is a measure of a chip's performance in applications that utilize multiple software threads, varies based upon a whole host of architectural factors. It also depends heavily upon how well the software scales with additional compute cores. As such, these results do not align perfectly based upon core/thread count, though it does serve as a decent litmus of multi-threaded performance. 

Be aware that architectures, caches, and interconnects profoundly impact these results, as all of these factors impact how well performance scales with additional threads. Performance rarely scales perfectly with the addition of more cores/threads, so the scaling factor of each processor architecture weighs in heavily on the value proposition of going with a higher core count processor.

It's noteworthy that both Ryzen 5000 chips beat out Intel's 18-core 32-thread Core i9-10980XE, and the Ryzen 9 5900X only comes with 12 cores. Again, pay attention to TDP - the Ryzen chips have a 105W ranking while Intel is specced at 165W.

Legacy Desktop CPU Benchmarks Hierarchy

Recognizing that a lot of older platforms are going to be paired with graphics subsystems multiple generations old, we wanted to define the top of our range to encourage balance between host processing and complementary GPUs. At this point, anyone with a Sandy Bridge-based Core i7 would realize a gain from stepping up to Coffee Lake or Kaby Lake, for example. And putting AMD's top FX CPUs next to a handful of Core i7s and those older Core i5s represents an upgrade to their status.

Currently, our hierarchy consists of 13 total tiers. The bottom half of the chart is largely outdated; you'll notice those CPUs dragging down performance in the latest games, regardless of the graphics card installed in your PC. If you own a CPU in that range, an upgrade could really take your experience to another level.

Really, it's the top five tiers or so that remain viable. And in that top half of the chart, an upgrade is typically worthwhile if it's a least a couple of tiers higher. Otherwise, there's just not enough improvement to warrant the expense of a fresh CPU, motherboard and RAM (not to mention the graphics card and storage solution you'd be considering as well).
