Intel Core i9-11900K vs. AMD Ryzen 9 5900X. Who’s the winner?

CPU temperature

Have you already created a perfect picture of the current generation of desktop processors or are you still willing to reconsider some things? For the start of HWC processor tests, we’ve picked the hottest hardware from Intel’s mainstream offer – the Core i9-11900K, which is going to compete against the AMD Ryzen 9 5900X in 40 chapters full of information. The older Core i9-10900K has also successfully been re-tested by the new methodology.

Today’s menu: 2× Core i9 (11900K + 10900K) and Ryzen 9 5900X

After relatively long preparations, we’ve finally managed to complete a detailed methodology for testing processors, which could provide a good baseline for the next few years.

Of course, we will not avoid making adjustments to the announced operating system Windows 11 over time, and we also know about the new 3DMark extension designed specifically for processor testing and the new F1 2021 coming out next month. We will incorporate these updates sooner or later. The date depends on when these get more stable and updates don’t significantly affect performance or performance metrics. We want to dedicate our time to processor testing in detail in the coming years. That is, in the case you’re interested, naturally.

We’ve also included your tests on request in the methodology. Whether it’s monitoring key parameters over longer periods of time under load, performance testing in DaVinci Resolve Studio and intergenerational comparison of the Core i5-11400F with the Core i5-10400F is coming soon as well. This time, however, we focus on the higher class.

We tested the latest Intel Core i9 desktop processor (11900K) not only against the Ryzen 9 5900X, but also a generation older Ci9-10900K. Although Rocket Lake is still being produced at 14 nm, it even has a two-core deficit compared to Comet Lak, but is already based on the Cypress Cove architecture with higher IPC, better performing single-core boost and support for the AVX-512 instruction set, which is missing in AMD Vermeer.

A complete overview of all specifications in the table below will be more useful than a hundred sentences. And before studying the tests themselves, do not miss the chapters with the methodology, where we describe the testing principles. The results may be more attractive than boring documentation, but in order not to get confused it is always good to know how the author achieved them.

Gaming tests

We test performance in games in four resolutions with different graphics settings. To warm up, there is more or less a theoretical resolution of 1280 × 720 px. We had been tweaking graphics settings for this resolution for a long time. We finally decided to go for the lowest possible (Low, Lowest, Ultra Low, …) settings that a game allows.

One could argue that a processor does not calculate how many objects are drawn in such settings (so-called draw calls). However, with high detail at this very low resolution, there was not much difference in performance compared to FHD (which we also test). On the contrary, the GPU load was clearly higher, and this impractical setting should demonstrate the performance of a processor with the lowest possible participation of a graphics card.

At higher resolutions, high settings (for FHD and QHD) and highest (for UHD) are used. In Full HD it’s usually with Anti-Aliasing turned off, but overall, these are relatively practical settings that are commonly used.

The selection of games was made considering the diversity of genres, player popularity and processor performance requirements. For a complete list, see Chapters 7–16. A built-in benchmark is used when a game has one, otherwise we have created our own scenes, which we always repeat with each processor in the same way. We use OCAT to record fps, or the times of individual frames, from which fps are then calculated, and FLAT to analyze CSV. Both were developed by the author of articles (and videos) from GPUreport.cz. For the highest possible accuracy, all runs are repeated three times and the average values of average and minimum fps are drawn in the graphs. These multiple repetitions also apply to non-gaming tests.

Computing tests

Let’s start lightly with PCMark 10, which tests more than sixty sub-tasks in various applications as part of a complete set of “benchmarks for a modern office”. It then sorts them into fewer thematic categories and for the best possible overview we include the gained points from them in the graphs. We then have the total score for single and multithreaded performance from Geekbench 5. Lighter test tasks are also represented by tests in a web browser – Speedometer and Octane. Other tests usually represent higher load or are aimed at advanced users.

We test the 3D rendering performance in Cinebench. In R20, where the results are more widespread, but mainly in R23. Rendering in this version takes longer with each processor, cycles of at least ten minutes. We also test 3D rendering in Blender, with the Cycles render in the BMW and Classroom projects. You can also compare the latter with the test results of graphics cards (contains the same number of tiles).

We test how processors perform in video editing in Adobe Premiere Pro and DaVinci Resolve Studio 17. We use a PugetBench plugin, which deals with all the tasks you may encounter when editing videos. We also use PugetBench services in Adobe After Effects, where the performance of creating graphic effects is tested. Some subtasks use GPU acceleration, but we never turn it off, as no one will do it in practice. Some things don’t even work without GPU acceleration, but on the contrary, it’s interesting to see that the performance in the tasks accelerated by the graphics card also varies as some operations are still serviced by the CPU.

We test video encoding in HandBrake and benchmarks (x264 HD and HWBot x265). x264 HD benchmark works in 32-bit mode (we did not manage to run 64-bit consistently on W10 and in general on newer OS’s it may be unstable and show errors in video). In HandBrake we use the x264 processor encoder for AVC and x265 for HEVC. Detailed settings of individual profiles can be found in the corresponding chapter 25. In addition to video, we also encode audio, where all the details are also stated in the chapter of these tests. Gamers who record their gameplay on video can also have to do with the performance of processor encoders. Therefore, we also test the performance of “processor broadcasting” in two popular applications OBS Studio and Xsplit.

We also have two chapters dedicated to photo editing performance. Adobe has a separate one, where we test Photoshop via PugetBench. However, we do not use PugetBench in Lightroom, because it requires various OS modifications for stable operation, and overall we rather avoided it (due to the higher risk of complications) and create our own test scenes. Both are CPU intensive, whether it’s exporting RAW files to 16-bit TIFF with ProPhotoRGB color space or generating 1:1 thumbnails of 42 lossless CR2 photos.

However, we also have several alternative photo editing applications in which we test CPU performance. These include Affinity Photo, in which we use a built-in benchmark, or XnViewMP for batch photo editing or ZPS X. Of the truly modern ones, there are three Topaz Labz applications that use AI algorithms. DeNoise AI, Gigapixel AI and Sharpen AI. Topaz Labs often and happily compares its results with Adobe applications (Photoshop and Lightroom) and boasts of better results. So we’ll see, maybe we’ll get into it from the image point of view sometime. In processor tests, however, we are primarily focused on performance.

We test compression and decompression performance in WinRAR, 7-Zip and Aida64 (Zlib) benchmarks, decryption in TrueCrypt and Aida64, where in addition to AES there are also SHA3 tests. In Aida64, we also test FPU in the chapter of mathematical calculations. From this category you may also be interested in the results of Stockfish 13 and the number of chess combinations achieved per unit time. We perform many tests that can be included in the category of mathematics in SPECworkstation 3.1. It is a set of professional applications extending to various simulations, such as LAMMPS or NAMD, which are molecular simulators. A detailed description of the tests from SPECworkstation 3.1 can be found at spec.org. We do not test 7-zip, Blender and HandBrake from the list for redundancy, because we test performance in them separately in applications. A detailed listing of SPECWS results usually represents times or fps, but we graph “SPEC ratio”, which represents gained points—higher means better.

Processor settings…

We test processors in the default settings, without active PBO2 (AMD) or ABT (Intel) technologies, but naturally with active XMP 2.0.

… and app updates

The tests should also take into account that, over time, individual updates may affect performance comparisons. Some applications are used in portable versions, which are not updated or can be kept on a stable version, but this is not the case for some others. Typically, games update over time. On the other hand, even intentional obsolescence (and testing something out of date that already behaves differently) would not be entirely the way to go.

In short, just take into account that the accuracy of the results you are comparing decreases a bit over time. To make this analysis easier for you, we indicate when each processor was tested. You can find this in the dialog box, where there is information about the test date of each processor. This dialog box appears in interactive graphs, just hover the mouse cursor over any bar.

Methodology: how we measure power draw

Measuring CPU power consumption is relatively simple, much easier than with graphics cards. All power goes through one or two EPS cables. We also use two to increase the cross-section, which is suitable for high performance AMD processors up to sTR(X)4 or for Intel HEDT, and in fact almost for mainstream processors as well. We have Prova 15 current probes to measure current directly on the wires. This is a much more accurate and reliable way of measuring than relying on internal sensors.

The only limitation of our current probes may be when testing the most powerful processors. These already exceed the maximum range of 30 A, at which high accuracy is guaranteed. For most processors, the range is optimal (even for measuring a lower load, when the probes can be switched to a lower and more accurate range of 4 A), but we will test models with power consumption over 360 W on our own device, a prototype of which we have already built. Its measuring range will no longer be limiting, but for the time being we will be using the Prova probes in the near future.

The probes are properly set to zero and connected to a UNI-T UT71E multimeter before each measurement. It records samples of current values during the tests via the IR-USB interface and writes them in a table at one-second intervals. We can then create bar graphs with power consumption patterns. But we always write average values in bar graphs. Measurements take place in various load modes. The lowest represents an idle Windows 10 desktop. This measurement takes place on a system that had been idle for quite some time.

Audio encoding (FLAC) represents a higher load, but processors use only one core or one thread for this. Higher loads, where more cores are involved, are games. We test power consumption in F1 2020, Shadow of the Tomb Raider and Total War Saga: Troy in 1920 × 1080 px. In this resolution, the power consumption is usually the highest or at least similar to that in lower or higher resolutions, where in most cases the CPU power draw rather decreases due to its lower utilization.

Power draw limits are disabled for both Intel and AMD processors, unlocked to the PL2/PPT level. As is the case with most motherboards, this is also set in the default settings. This means that the “Tau” timeout after 56 seconds does not reduce power draw and frequencies even under higher load, and performance is stable. We considered whether or not to accept the more economical settings. In the end, we won’t, on the grounds that the vast majority of users don’t do it either and thus the results and comparisons would be rather uninteresting. The solution would indeed be to test with and without power limit, but this is impossible from a time point of view in the context of processor tests. However, we won’t ignore this issue and it will be getting space in motherboard tests where it makes more sense to us.

We always use motherboards with extremely robust, efficient VRM, so that the losses on MOSFETs distort the measured results as little as possible and the test setups are powered by a high-end 1200 W BeQuiet! Dark Power Pro 12 power supply. It is strong enough to supply every processor, even with a fully loaded GeForce RTX 3080, and at the same time achieves above-standard efficiency even at lower load. For a complete overview of test setup components, see Chapter 5 of this article.

Methodology: testy temperature and clock speed tests

When choosing a cooler, we eventually opted for Noctua NH-U14S. It has a high performance and at the same time there is also the TR4-SP3 variant designed for Threadripper processors. It differs only by the base, the radiator is otherwise the same, so it will be possible to test and compare all processors under the same conditions. The fan on the NH-U14S cooler is set to a maximum speed of 1,500 rpm during all tests.

Measurements always take place on a bench-wall in a wind tunnel which simulates a computer case, with the difference that we have more control over it.

System cooling consists of four Noctua NF-S12A PWM fans, which are in an equilibrium ratio of two at the inlet and two at the outlet. Their speed is set at a fixed 550 rpm, which is a relatively practical speed that is not needed to be exceeded. In short, this should be the optimal configuration based on our tests of various system cooling settings.

It is also important to maintain the same air temperature around the processors. Of course, this also changes with regard to how much heat a particular processor produces, but at the inlet of the tunnel it must always be the same for accurate comparisons. In our air-conditioned test lab, it is currently in the range of 21–21.3 °C.

Maintaining a constant inlet temperature is necessary not only for a proper comparison of processor temperatures, but especially for unbiased performance comparisons. Trend of clock speed and especially single-core boost depends on the temperature. In the summer at higher temperatures, processors may be slower in living spaces than in the winter.

For Intel processors, we register the maximum core temperature for each test, usually of all cores. These maximum values are then averaged and the result is represented by the final value in the graph. From the outputs of single-threaded load, we only pick the registered values from active cores (these are usually two and alternate during the test). It’s a little different with AMD processors. They don’t have temperature sensors for every core. In order for the procedure to be as methodically as possible similar to that applied on Intel processors, the average temperature of all cores is defined by the highest value reported by the CPU Tdie sensor (average). For single-threaded load, however, we already use a CPU sensor (Tctl/Tdie), which usually reports a slightly higher value, which better corresponds to the hotspots of one or two cores. But these values as well as the values from all internal sensors must be taken with a grain of salt, the accuracy of the sensors varies across processors.

Clock speed evaluation is more accurate, each core has its own sensor even on AMD processors. Unlike temperatures, we plot average clock speed values during tests in graphs. We monitor the temperature and clock speed of the processor cores in the same tests, in which we also measure the power consumption. And thus, gradually from the lowest load level on the desktop of idle Windows 10, through audio encoding (single-threaded load), gaming load in three games (F1 2020, Shadow of the Tomb Raider and Total War Saga: Troy), to a 10-minute load in Cinebench R23 and the most demanding video encoding with the x264 encoder in HandBrake.

To record the temperatures and clock speed of the processor cores, we use HWiNFO, in which sampling is set to two seconds. With the exception of audio encoding, the graphs always show the averages of all processor cores in terms of temperatures and clock speed. During audio encoding, the values from the loaded core are given.

Conclusion

The fact that the multithreaded performance of the Core i9-11900K will be lower than that of the Ryzen 9 5900X was already determined by the composition of its cores—eight is simply not enough against twelve. Those eight Ci9-11900K cores are not even enough against ten cores of the older Ci9-10900K. However, Rocket Lake has higher rate of instructions per cycle and in some multithreaded tests lags behind the Comet Lake with more cores only slightly, while the Ci9-11900K has 200 MHz lower all-core boost clock.

The Ci9-11900K is on average faster in games than the Ci9-10900K, but exceptions apply when the Comet Lake keeps the lead due to the lower L2 and L3 cache latency. Such games include Assassin’s Creed: Valhalla. For the vast majority of games, however, the Rocket Lake achieves higher performance, which is always redeemed by higher power consumption though. While so far (including the situation with Ci9-10900K) it has stayed at the limit of 125 W, the Ci9-11900K exceeds this value quite significantly. Of the tested games, the most CPU demanding was Total War Saga: Troy, exceeding the PL1 (= TDP) limit by up to 28 W. On motherboards that comply with Intel’s recommended Tau time limit for maximum Boost, there may be a slight decrease in game performance.

But the comparison of Ci9-11900K with Ryzen 9 5900X is remarkable in this respect. The Rocket Lake’s lead in average gaming performance is minimal and only noticeable in higher resolutions, from QHD (1440p) onwards. The R9 5900X is better in FHD, where this processor can be a better choice for setups with lower resolution (FHD) and high refresh rate monitors. For higher resolutions, Intel and its Core i9-11900K are still performing better overall. But this is not always true (such as in MS Flight Simulator,where the Ryzen 9 5900X is also faster in UHD), but in most cases the highest performance Rocket Lake is in the lead in higher resolutions.

Rocket Lake, compared to Comet Lake, also has a significantly higher single-threaded performance. We have already mentioned higher IPC, and when we add that 100–150 MHz higher core clock rate is achieved in practice, only Ryzen 9 is the equivalent opponent again. And it’s like on a seesaw, AMD is on top in some respects and the efficiency or performance per watt is very similar, too.

However, the efficiency in the use of all cores is clearly on the side of AMD. But watch out for video encoding on the Core i9-11900K. Rocket Lake uses the AVX-512 instructions in the default settings with the x264 encoder, which results in a significant increase in power consumption, which easily exceeds the second power draw limit (PL2) and tops at 300 W. This is because the computing of 512-bit instructions processes 2x more numerical values at once, and also the transfer of data with twice the width is more energy-intensive, which transfers to the already bad efficiency.

This increase in power consumption could be offset by a decrease in clock speed and voltage while using the AVX-512, but the Core i9-11900K on our test motherboard did not behave like this and did not reduce the clock, resulting in extreme power consumption.. This furious Rocket Lake is already kind of difficult to cool with conventional coolers. But cooling small AMD chiplets is difficult as well, even at low power draw of around 60 W. Typically, it is a single-threaded load, where it is sometimes a problem to even cool one core to a temperature that will not be limiting for achieving stable boost. Its operation dynamically depends on the temperature.

But in conclusion, the 12-core 5900X cannot be blamed for much, except for the more complicated heat transfer. Performance per watt is higher not only in gaming. In non-gaming tasks, the price-performance ratio is also significantly better. In games, the R9 5900X is similar to the Ci9-11900K, but overall it is definitely a processor that has universally higher performance with better operating characteristics. And since we’re already in a relatively high-end class, the AMD Ryzen 9 5900X well deserves our “Top notch” award for its features.

On the other hand, the Core i9-11900K may be a slightly better choice for high-end gaming computers. However, multi-threaded performance in relation to price is worse (but not bad), but again, this processor can be cooled better, even though it has lower efficiency at maximum performance. This processor definitely does not deserve the hate it receives. The outdated manufacturing process is one thing, but the main thing is the present performance advance compared to the previous generation. For some tasks, the Core i9-11900K processor may be of particular interest for high and stable single-threaded performance. That’s why we’re giving this processor, like the Core i9-10900K, our “Approved” award.
