Today we're finally bringing you the epic gaming battle between the Ryzen 7 2700X and the Core i7-8700K that so many have requested. From AMD, the Ryzen 2700X offers 8 cores and 16 threads, which are clocked between 3.7 and 4.3 GHz, depending on the workload. From Intel, the Core i7-8700K offers two cores less for a 6-core / 12-thread configuration, but what this chip lacks in cores, it makes up for in the clock speed, which is between 3.7 GHz and 4.7 GHz is working.
Both CPUs are unlocked, which means that they can be overclocked. We suspect that many of you who are interested in one of these CPUs will overclock. That is why we did it. However, it is worth noting that the 2700X is basically maximum and overclocking all cores to 4.2 GHz only increased game performance by up to 5%, so it really isn't worth it. Nevertheless, we achieved the maximum performance of both CPUs in our tests, so that everything is a fair game.
To test the Core i7-8700K, we put together a rig with the Gigabyte Z370 Aorus Gaming 7 with 16 GB DDR4-3400 Samsung B-Die memory using The Stilts timings. The CPU was overclocked to 5 GHz and the Corsair Hydro Series H100i v2 in the Corsair Crystal 570X is cooled with this frequency.
Then we have the Asus ROG Crosshair VII Hero for the Ryzen 7 2700X Rig with 16 GB DDR4-3400 Samsung B-Die memory, also using The Stilts timings. The 2700X was overclocked to 4.2 GHz and this time we use the Corsair Hydro H150i Pro in the Corsair Crystal 570X.
We have a total of 35 games on the menu and each game has been tested with the GeForce GTX 1080 Ti at 720p, 1080p and 1440p.
ARMA 3, Ashes of Singularity, Assassins Creed, Rainbow Six Siege, Battlefield 1
First we have ARMA 3 and here the 8700K was 13% faster at 720p and 1080p if you compare the average frame rate. As soon as we reach 1440p, the GTX 1080 Ti becomes a performance-limiting component, and as a result the margin shrinks to 8% in favor of the 8700K.
Crazy quality settings were used for the benchmarking of Ashes of the Singularity, which is a serious GPU bottleneck even at 720p. In this case, both CPUs were able to maximize the GTX 1080 Ti at all three resolutions tested.
Passing through the city of Alexandria in Assassin's Creed Origins, the Core i7-8700K delivered up to 7% more power at 720p, but strangely 10% more at 1080p and then 11% at 1440p. It is extremely rare for the power margin to increase as we increase the resolution, but then ACO is sometimes a strange animal.
Next we have Rainbow Six Siege and here the 8700K was 12% faster at 720p for the 1% low result and 9% faster for the average frame rate. The margin shrinks considerably at 1080p, here the Core i7 processor was only 5% faster. At 1440p we see an identical performance, whereby both CPUs enable extreme performance.
When testing with Battlefield 1, we find a fairly balanced fight, although it is sometimes an advantage that Intel. At the low 720p resolution, the 8700K was up to 12% faster since the 2700X seems to be 116 fps for the 1% low result.
If we switch to 1080p we find similar margins for frame time performance, here Intel was 11% faster. Still, it was interesting to see how the 2700X on the 8700K is up close for the average frame rate, usually the average frame rate at which Intel is pulling away.
After all, at 1440p we are mainly bound to the GPU, also with the GTX 1080 Ti, and here the 8700K and 2700X offer an identical experience.
