Rendering on Intel Core i7-10700K

Intel can't contest AMD's commanding lead in rendering applications on mainstream desktop platforms, or any other platform for that matter, but it can compete on price and reduce performance disparities. 

The Core i7-10700K beats or matches the 9900K across the full spate of our rendering tests, both at stock and overclocked settings, but the 12-core Ryzen 9 3900X is a potent foe. That chip retails for roughly $415, which is a worthy $28 premium over Intel's MSRP if you're focused on productivity work. The 3900X's bundled cooler also sweetens the deal. 

The Ryzen 7 3800X carves out a few wins, but the disparity between the two chips is slim at stock settings, and the Core i7-10700K leads after overclocking. 

Moving on to the single-core rendering workloads, the Intel processors maintain a solid lead, particularly after overclocking. 

Encoding on Intel Core i7-10700K

The single-threaded LAME and FLAC encoding tests respond well to per-core performance, giving the overclocked 10700K a convincing position in the performance charts. 

AMD's Ryzen can't match Intel's single-threaded performance in those lightly-threaded encoding workloads, but the chips are more competitive in the threaded SVT-AV1 encoder built by Intel and Netflix. Again, the 3800X and 3700X take the lead over the 10700K at stock settings, but those deltas are slight. After overclocking, the 10700K regains the lead. 

The threaded HandBrake x264 and x265 tests really speak to the AVX performance improvements AMD made to the Zen 2 architecture. The stock 10700K lags the Ryzen 7 3800X and 3700X in the x264 test, but surpasses the chips in the AVX-heavy x265 benchmark. Overclocking helps separate the 10700K from the pack, but the Ryzen 9 3900X again asserts itself with leading performance. 

Web Browsing on Intel Core i7-10700K

Browsers tend to be impacted more by the recent security mitigations than other types of applications, so Intel has generally taken a haircut in these benchmarks on fully-patched systems.

Single-threaded performance still reigns supreme in these tests, so it isn't surprising to see the Comet Lake chips largely take the lead at stock settings, and completely separate themselves from the pack after tuning. The Ryzen chips fare better in the Microsoft Edge benchmark because it uses the copious helping of threads more effectively. 

Office and Productivity on Intel Core i7-10700K

Clock rates benefit the majority of the GIMP image processing and Microsoft Office tests, both of which benefit from the Core i7-10700K's high boost clocks. 

Compilation, Compression and AVX on Intel Core i7-10700K

At stock settings, the Ryzen 3800X and 3700X outperform the Core i7-10700K, and even the 9900K, in the LLVM compilation benchmark. Overclocking swings the lead in the 10700K's favor, but not by a large margin. The Ryzen 9 3900X again proves its mettle in this threaded task, easily sweeping the Intel processors.  

The 7zip and Zlib compression/decompression benchmarks rely heavily upon threading and work directly from system memory, thus avoiding the traditional storage bottleneck in these types of tasks. As we've come to expect, the Ryzen processors dominate in 7zip compression tasks. The 10900K is a bit more competitive in the decompression test, but even overclocking the 10700K doesn't give it an edge over any Ryzen processor. 

The heavily-threaded y-cruncher benchmark, which computes pi using the taxing AVX instruction set, finds the 10700K notching minor gains over the 9900K while trailing the Ryzen 3000 series at stock settings in the threaded test. Overclocking boosts the 10700K up the charts, but the Ryzen 3800X and 3900X still lead. Clock rates come into play during the single-threaded y-cruncher test, so the Intel processors take the top of the chart.

    Wow that's high power consumption! Good thing you are running liquid cooling! Compare that to the AMD 3700X at half the power!

    Look at the shorter tests, the Intel systems seems to do better until their turbo runs out. AMD seems to do better with anything that takes more time.

    I realize that both AMD and Intel systems are overclocked but the AMD systems seem to do better with memory tuning, maybe instead of just using PBO (a one click solution), take the same time you use for the Intel processors and put that into the memory. AMD would show even better in games and anything that was memory intensive.

    1440p gaming would be more relevant! I do realize it doesn't make for good looking graphs but 1080p is not the typical use case for this CPU and comparable GPU.

    Good review overall. Pretty fair way of presenting the information. Good memory choices. Efficiency focus was great to see.

    Way better than the typical casting AMD CPUs in bad light, for example where Toms put the 3400G ($159) against the Intel 9700k($379.00).

    Good review, too bad at this price point you only show 1920x1080p game results.

    I understand thats the only way to keep GPU from been a "bottleneck", but if I was to spend this much money I would aim for playing at 1440p High details.

    I still think that no matter what you wana play, the resolution and/or refresh rate, at this point in time the best bang for the buck for ultrafast FPS is the Core i5 10600K + high speed memory, and you feel like it some quick brainless overclocking.

    Other than that just pick the Ryzen your wallet can buy and be happy.

    Look... Can we actually get gaming benchmarks with modern games and at higher resolutions?

    Intel keeps on saying that they are better for gaming because of single-threaded 1080p benchmarks, but we don't game like that with 2080ti cards. We don't build $2000 machines with one of the most expensive gaming cards to run 1080p ffs.

    Are you going to give us next gen graphics card benchmarks only at 1080p?

    If not, can we actually see what this new CPU will look like in comparison to others at resolutions that we use? We've been watching all the review sites doing this for three or four years now... It's Intel's marketing strategy, and you are letting them do it, and playing along! It's a problem, because we don't have any reviews that actually show us what to buy for the way that we actually play games. These are reviews are actually useless for gamers.

    I find it downright shocking to see that popular hardware review sites such as Tom's are still harping so much on HD gaming results.
    Yes, game results at HD are less GPU bound, but it only paints Intel in a good picture while hiding a rather shocking truth - that AMD is incredibly gaming competitive at the world's sweet spot for gaming resolutions. Q H D. (Typically 2560x1440).Tom's explicitly stated in the past that QHD is the best area for gaming given that screens today with G/Fsync/144hz+ options cost less than $500 and are very affordable in general, today. 4K is still too high for most GPU's to handle, meaning that QHD fills a good middle ground at the end of the day, beating HD at higher image quality.

    Really Tom's, get your act straight. It's time to nudge your audience towards higher gaming echelons.
    Start publishing QHD CPU results in addition as this will entice people to make the switch towards higher res gaming but also this - AMD Ryzen CPU's in general are less than 5% slower than Intel chips at QHD or 4K FPS. Intel is therefore NOT the indisputable king as no god given person can tell such a small difference in high res FPS. Enough with the gaming myths! Ryzen CPU's tend to pack more cores that actually makes them far more future prove. If most of those cores sit idle in today's gaming, who cares? Wouldn't you rather have enough cores in reserve for more future demanding games and enjoy streaming/recording quality with extra muscle under the hood to enjoy less stutter? Call me stupid, but to me this actually makes Ryzen a better gaming choice.

    Your article adds to this whole HD stagnation thing that's been going on for over 10 years. Over 90% of steam players still game at HD. It's time to give em reason to make the next push - QHD and then 4K.
    Make a start. I challenge Paul Alcorn to do a "world sweet spot QHD CPU FPS" article. Get around 10 people or so to game on both Intel and AMD machines. Gather the results and lets see if Intel still holds the crown.

    The only downside is how hot the 10700K gets. When I got mine, I ran a stress test at stock and it hit 74 degrees with a Fractal Celsius S24 AIO with my case open (Define R6) for maximum airflow and all fans running. It gets into the mid 80's when the case is closed. I'd assume I'd get those temperatures with the case open when overclocking and that's a bit much.

    I will say this though, my new system runs Doom Eternal really well. Basically everything cranked to high or ultra at 2K resolution with a GTX 1070.

    This year, many will be building new computers mostly dedicated to Microsoft Flight Simulator 2020. In the past, flight sims were more likely to be CPU-bound than GPU-bound, but it's not clear that that's any longer the case. Is there any way to predict before final release of this much-anticipated game whether it will benefit more from single-core clock speed or multi-threading? Would anyone hazard a guess on whether to plan an Intel or Ryzen build?

    You should wait for reviews when its launched.

    Other than that this is the best you can check right now: https://www.pcgamer.com/microsoft-flight-simulator-system-requirements/
    Im guessing any Ryzen 5/7 3xxx will play nice, probably thye Ryzen 7 3700X could be a cheaper, yet very good option vs the i7 10700K.

    And if rumors becomes true the new Ryzen 4xxx could be a new jewel for gaming. But that wont be out till atleast the end of september.

    There are still 1080p 240hz monitors that are being sold.
    1080p ultra is very realistic, Paul did not test it at 1080p low he tested it on max settings.
    It is not like some review sites that test at 720p low or even worse at 480p.
    This is a cpu review not a gpu.
    In gpu review I would expect it to be tested in 1080p up to 4k, maybe even 8k.

    True, but it does not change the fact that there are also more and more 1440p monitors sold everyday. And when you spend this amount of money for a CPU many people will also consider a high end GPU with a 1440p monitor for gaming, thus it will be very nice to have those results.

    DX12 should remove alot of CPU bottleneck and hopefully we'll see great core scaling if all pans out for the engine. I for one would like to see how the engine handles scenery draw and how smooth everything will translate to FPS.
