Benchmarks: Rainbow Six Siege, Total War Warhammer 2
Tom Clancy's Rainbow Six Siege is another CPU demanding title and at 720p the new Core series pushed over 180fps at all times. The 8700K was almost 40% faster than the Ryzen 7 1800X when comparing the minimum frame rate, so that's obviously a pretty massive margin. The 7700K was also 30% faster than the 1800X, so let's move to 1080p.
That 40% margin seen previously has been reduced to 30% in favor of the 8700K over the 1800X, meanwhile the 7700K is just 19% faster than the eight-core Ryzen 7 CPU.
At 1440p those margins close right up and now the 1800X is able to roughly match the Intel CPUs. The R5 1600X still trails by a reasonable margin though as it dropped down to 116 fps for the 1% low result.
Total War: Warhammer 2 is another DirectX 11 game that's quite CPU intensive but doesn't really call for more than a quad-core processor. Here the 8700K was actually slightly slower than the 7700K by a few frames, but even so it was 32% faster than both the 1800X and 1600X CPUs when comparing their minimum frame rate results.
The move from 720p to 1080p pretty much neutralizes the field, the only straggler here is the 1500X, while at 1440p even the 1500X catches up and now the experience is much the same across all eight CPUs.
