1440p and 4K Gaming
While gaming at 1080p is an important benchmark for CPU performance in games, with the GPU bottleneck eliminated, users game at many different resolutions. To get a better an idea of real-world gaming performance for more configurations, we decided to run through the same gauntlet of games in two common resolutions, 2560×1440 and 3840×2160 (4K UHD).
Overall, the performance gap between the Ryzen 7 2700X and the Core i7-8700K drastically lowers when gaming at 2560×1440. In most games, the performance delta remains at a few FPS in favor of the 8700K. However, a few titles creep into the 8-15 FPS range, such as Civilization VI, Ashes of the Singularity: Escalation, and F1 2017.
Lastly, For Honor stands alone as the one title showing a substantial performance benefit for the AMD processor of around 6% to the R7 2700X.
At the very GPU-dependant 4K screen resolution, the performance gap between the Ryzen 2000 series and Intel's Coffee Lake processors is mostly gone. However, the slight edge still goes to the Coffee Lake CPUs by a few frames per second in all games tested except for the graphics portion of Civilization VI.
For 4K gaming, it's fair to say the differences between the Ryzen 2000 series and Intel 8th generation processors is largely negligible. However, users looking to game at resolutions under 4K, especially with popular high-refresh-rate displays, should consider their processor choice if they are looking at using their PC for purely gaming use cases.
