AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?

I’ve compared the Ryzen 7  5800X against Intel’s i7-10700K   processor in games and applications  to help you decide which to pick

CPU spec differences

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Both processors have 8 cores and 16 threads.  The 10700K can reach higher clock speeds,   but the 5800X has double the cache.  The 5800X also costs more money,   so let’s dive in and find out  if it’s worth paying more for.

Test PC

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Both processors were tested in the same  system, but I’ve had to change motherboards.   For the 10700K I’m testing with  the MSI Z490 ACE motherboard,   and for the 5800X I’m using  the ASRock X570 Taichi. The rest of the components  were otherwise the same,   I’ve tested with 32gb of DDR4-3200 memory  running in dual channel at CL14 and with   MSI’s GeForce RTX 3090 Gaming X Trio  graphics card to minimize bottlenecks. Neither processor comes with a cooler,   so I’ve used my Fractal S36 AIO with Noctua  NT-H2 thermal paste for comparable results.

Overclocks

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?I’ve tested both CPUs at stock, and with the  following all core overclocks applied, 5.1GHz   on the 10700K and 4.7GHz on the 5800X. The Intel  system also had MCE disabled with no power limits. With that in mind we’ll first check out  the differences in various applications,   as well as power draw and thermals,  followed by gaming tests afterwards,   then finish up by comparing some  performance per dollar metrics.

Application tests

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Starting out with Cinebench  R20 we can see the 5800X is 22%   faster than the 10700K in single core at stock,  a great result given this is an area where Intel   has traditionally had the lead. When it comes to  multicore performance, the 5800X was still 24%   faster than the Intel chip, again a great result  considering both have the same core and thread   count. With both processors overclocked  the 5800X is actually a little worse,   and this is because the all core  overclock limits single core boost. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?I’ve also tested the older Cinebench  R15 as a lot of people still use it   so you can compare my results, the margins  were quite similar to R20 so let’s move on. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?I’ve tested Blender with the BMW and Classroom  benchmarks. This is a multicore workload,   and the 5800X was completing the  BMW test 10% faster than the 10700K,   and the classroom test 17% faster at stock.

With  both overclocked though, the 5800X was now just   3% and 10% faster respectively in the same tests,  and this is because the overclock on the 10700K   makes a bigger improvement, but either way a stock  5800X is still faster than the overclocked 10700K. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?The V-Ray benchmark is another rendering workload,  at stock the 5800X was scoring 26% higher than   the 10700K, then when both are overclocked  the 5800X is still able to score 19% higher. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?The Corona benchmark also uses the processor  to render out a scene, though in this multicore   test the difference was less pronounced, with  the 5800X 17% faster than the 10700K at stock,   and then 11% faster once both are overclocked.  We can see that the 5800X overclock only allows   the test to complete a second faster, while  the 10700K overclock shaves off 6 seconds. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Handbrake was used to convert one of  my 4K laptop review videos to 1080p.   I wasn’t seeing any difference to the  5800X whether or not it was overclocked,   while the 10700K again was able to offer much  better gains with the overclock in place,   but again even with the 10700K overclocked  the stock 5800X was still 11% faster. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Adobe Premiere was used to export one of my laptop  review videos at 4K. I’ve tested with both VBR 1   pass, which should make use of Intel’s quicksync  on the 10700K, and 2 pass which should be   heavier on the processor. At stock the 5800X was  completing the video export 11% faster than the   10700K in the 1 pass test, but the 2 pass test was  17% faster as there’s less hardware acceleration.AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU? I’ve also tested Adobe Premiere but  with the Puget Systems benchmark tool,   as this tests for more things like live  playback rather than just raw video export   times. The 5800X was scoring 12% higher at  stock, and 8% higher with both overclocked. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Adobe Photoshop was also tested with  the Puget Systems benchmark tool.   Like some of the other tests, the overclocked  5800X result was actually a little worse,   but even with the 10700K overclocked to  5.1GHz the 5800X was still scoring 11% higher. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?I’ve used 7-Zip to test compression  and decompression speeds,   and Ryzen chips have always had a huge  advantage over Intel in this test which   continues here. At stock the 5800X was 23%  faster in compression, and then 37% faster   in decompression, one of the biggest  differences out of all apps tested. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?On the other hand, VeraCrypt was used to  test AES encryption and decryption, and   the differences between the two processors here  were the smallest out of all applications tested   with the 5800X just 9 to 10% faster at stock, or  less than 5% faster with the overclocks in place. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Microsoft Excel was tested using the  Hardware Unboxed large number crunch test,   and this test saw the biggest difference out  of all applications tested, likely owing to   the 5800X having double the cache. The 5800X  was over 40% faster than the 10700K at stock,   and was still completing the task  33% faster with both overclocked.AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU? The differences in single core performance in  Geekbench are quite similar to what was seen in   Cinebench previously, with the overclocked  5800X actually dropping back a little,   regardless it’s still a clear win for  the 5800X at stock or overclocked.

Application differences

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Here’s how AMD’s Ryzen 7 5800X compares against  Intel’s i7-10700K with both processors at stock   in all of the applications tested. The 5800X  was faster in all instances, though as we can   see results vary by workload.

I was surprised how  much ahead the 5800X was in the single core tests,   just for comparison the 3800XT from last  generation was behind the 10700K there. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?The 5800X is still on top in all tests once  both processors have been overclocked as   far as I could push them, though overclocked  results will of course vary based on factors   like silicon lottery. The performance  gap does narrow in here as the 10700K   has more overclocking headroom, but it still  can’t catch the 5800X. Based on my results,   it doesn’t really seem worth overclocking  the 5800X, the easy gains just aren’t there.

Power draw, thermals, clock speeds

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?When we look at the total system power draw  from the wall with the blender test running,   the 5800X system is using slightly more  power with both processors running at stock,   but don’t forget it was also completing  this test 17% faster for 3% more wattage.

Things get interesting with both overclocked.  The 5800X is actually using slightly less power,   and this seems to be because  my manually set voltage was   less than what it would automatically boost up to.

Higher power draw typically results in  more heat, and that was the case here. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?  The 5800X was running hotter at stock, the  10700K was a fair bit cooler comparatively,   but once the 10700K was overclocked it  was now reaching higher temperatures. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?These are the clockspeeds being reached during  these same tests, so at stock both were fairly   similar, and given the 5800X was actually clocking  a little lower but performing better in all tests,   it would appear that Zen 3 has superior  instructions per clock or IPC.

With the overclocks   in place the 10700K is capable of higher speeds,  and this is why with both overclocked the 10700K   sees a larger performance boost, but even  so in all cases the 5800X was still faster.

Gaming tests

Let’s get into the gaming results next, I’ve  tested 9 games at 1080p, 1440p and 4K resolutions.

Shadow of the Tomb Raider was tested with the  games benchmark tool. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?At 1080p down the bottom   of the graph, the 5800X was reaching 6% higher  average FPS. At 1440p it was only 2% ahead,   then no change at 4K as the processor  generally matters less at higher resolutions. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Microsoft Flight Simulator was tested  in the Sydney landing challenge.   At 1080p the 5800X had a 4% lead, though as  we can see that’s only a 1 frame difference,   good luck noticing that when  actually playing. Jokes aside,   it’s still impressive that Zen3  is able to beat Intel in games. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Death Stranding was tested by running through  the same part of the game on both systems,   and is a title I’ve noticed that tends  to do quite well with Zen 3. At 1080p,   the 5800X was reaching 12% higher average  frame rates when compared to the 10700K,   but this lead disappears at higher resolutions. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Battlefield V was tested in campaign mode, and  there were no major differences between the two,   which were around 1 FPS different  either way regardless of resolution,   and both were hitting the 200 FPS cap at 1080p. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?I had to put CS:GO to the test as AMD were  claiming some pretty big gains with Zen 3,   and I was seeing big improvements with the  5800X which is quite impressive as this is   a title where Intel has always had the  lead. At stock the 5800X was 27% faster   in average frame rate at 1080p, though the  1% low difference was lower at 6% higher. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Red Dead Redemption 2 was tested with the games  benchmark. Again the 5800X was faster in all   instances, with a 7% lead over the  10700K at 1080p and 5% faster at 1440p. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Rainbow Six Siege was doing slightly better  on the 10700K in average frame rate, but still   it’s probably not that big of a difference  that you’re going to notice in any case,   especially at 1080p where both are spitting  out more than 500 FPS with max settings. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Assassin’s Creed Odyssey was also tested  using the games built in benchmark tool,   and was another where the 10700K was doing a  little better regardless of resolution in use. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Far Cry New Dawn was tested  with the games benchmark too,   and the 5800X was ahead in average  frame rates at all setting levels.

Gaming differences

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Over all 9 games tested, the 5800X was 6%  faster than the 10700K in average FPS. It’s   worth noting that Battlefield 5 only saw no  difference because both chips were capable   of reaching the 200 FPS cap, so that may be  holding the average back a little. That said,   the average is clearly boosted up  by the crazy CS:GO performance,   so if we don’t count that the 5800X is instead 3%  faster than the 10700K in this selection of games. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?When we step up to 1440p the 5800X is now under 2%   faster on average. Higher resolutions  start becoming more GPU dependent,   so the difference in processor starts to matter  less, but regardless still a win for the 5800X. AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?This trend continues at 4K, where the 5800X was  now under 0.4% faster than the 10700K on average,   and even if we remove the CS:GO outlier both  processors are still extremely close together   on average. I only tested 4K to outline  how the processor basically doesn’t matter.

Cost per frame value

AMD Ryzen 7 5800X vs Intel i7-10700K - Best 8 Core CPU?Despite the 5800X performing better in  most cases, the 10700K is the winner   in terms of value as it’s currently $70  cheaper than the 5800X’s launch price.   

The cost per frame differences get  bigger at the higher resolutions   because the frame rates get closer to being  the same so the price difference matters more. Don’t get me wrong, the 5800X is definitely a  capable gaming processor, but it needs to be   cheaper to be competitive against the 10700K.

It  was a different story when I compared the 5600X   against the 10600K, the 5600X was a clear  win as the price difference was only $25.   Basically the other Zen 3 processors  were much more exciting when compared   to their Intel counterparts, the 5800X  is a bit less exciting comparatively.

Conclusion

If you’re only or mainly gaming, the 10700K may  make more sense, but if we factor in productivity   focussed applications, well the 5800X blows  the 10700K away, you’ll just have to decide if   it’s worth paying $70 more or 18% more money  for this level of performance improvement. It’s also worth considering that these  price differences are for the CPU only,   the percentage differences become less in the  context of say a new $1500 system for instance,   where the processor makes  up a fraction of the cost. Personally I’d pay the extra money for the  5800X as I don’t do a whole lot of gaming,   but that’s just me - if I was primarily gaming  and wanted an 8 core processor, the 10700K   is looking attractive at its current price.

Let  me know which you’d pick down in the comments. I’ll also be comparing the 5800X with the 3700X  from last generation soon, and I’ve got plenty   more Zen 3 comparisons on the way.
