Civilization VI, Dishonored 2, Resident Evil 7
Testing Civilization VI using DX12 you might expect it to favor the 6-core CPU, I know I did. Yet we find quite the opposite here, again I went back and reconfirmed these results as they just didn't seem right. Turns out they are and we find another game where the 7700K offers almost 30% more performance than the 7800X.
Dishonored 2 favors the quad-core CPU by a 12% margin when comparing the minimum frame rate and we see much the same when comparing the average frame rate as well. The 7700K is clearly the faster CPU for this title.
The 7800X does trail the 7700K by a 7% margin when stock but once overclocked both processors deliver similar performance and are presumably getting the most out of the GTX 1080 Ti.
