For our next series of tests, we moved on to some game-related metrics with 3DMark, specifically the physics benchmark that's part of the Fire Strike test. To run this test, we simply create a custom 3DMark run consisting solely of the physics test, which is CPU dependent, and report the results...

Taking the GPU out of the Equation |

The Ryzen 3 processors we tested sandwiched the Core i3-7350K here, but couldn't quite catch the Core i5s or previous-generation 8-core AMD processors.

1080P and 4K Gaming With GeForce GTX 1080 |

We also ran some high-resolution game and graphics tests on AMD's new Ryzen 5 processors using 3DMark, Hitman, and Ashes Of The Singularity. We used 3DMark's Fire Strike Ultra preset, and both of the games were run with all in-game graphics options set to their maximum values, save for the Ashes 1080P test where we used the "High" preset. Note, we also swapped out the GTX 960 for a more powerful GeForce GTX 1080 here.
The 3DMark Fire Strike results are tightly grouped, because the GPU is the bottleneck. The Ryzen 3's are able to keep the GPU fed here, however, and finish in a dead heat with the Core i5 processors.
The DX12 version of Hitman wasn't quite as kind to the Ryzen 3 processors. Their average framrates were playable, but they clearly trailed the Core i5s and Core i3 here.
Ashes Of The Singularity tells a similar story to Hitman, but performance is more tightly grouped. It's not realistic to expect AMD's entry-level processors to hang with higher end chips while gaming, but the do have plenty of gaming chops for the money.
