The market for people buying an expensive CPU and using it for gaming at 1080p is likely to be very slim. What 1080p does is give a good indication of the CPU’s raw gaming performance as GPU power is sufficient to push frame rates to a level where the CPU and memory limitations can be observed.
We supplement the 1080p gaming results with a trio of games tested at 4K using the same Titan X Pascal graphics card that pushed through our 1080P suite. That saving against Intel’s competing CPUs with similar core counts could buy a nice 4K monitor, so we will show how Ryzen 5 performs at such a resolution.
Gears of War 4
We run the built-in benchmark using a 4K resolution and the same settings as the 1080p test (Ultra quality preset, Async Compute enabled).
Game version 18.104.22.168 used for current testing (earlier version used for previous testing).
Note: The Core i7-2700K and i7-4790K are not shown in Gears of War 4 as the game download was too large to install on their system SSD and the clunky Windows Store platform gives errors when moving games installed on a secondary SSD between test systems.
Grand Theft Auto V
We run the built-in benchmark using a 4K resolution and the same settings as the 1080p test (generally Maximum quality settings including Advanced Graphics). VRAM usage at 4K, according to the built-in GTA V counter, is 4171MB.
The Witcher 3 Wild Hunt
We run our custom 107-second benchmark in a densely-populated town area using a 4K resolution and the same settings as the 1080p test (Maximum quality, Nvidia settings disabled).
4K gaming performance shows tighter grouping in the results between processors as such emphasis is put on GPU horsepower. GTA V still runs faster on the Intel Core i5-7400 but the performance drop to AMD’s Ryzen 5 1500X is greatly reduced. The Witcher 3 and Gears of War 4 show very similar performance between Ryzen 5 1500X and Core i5-7400.
