Ryzen CPUs perform quite badly in games in comparison to their Intel counterparts. ARSTehcnica's review of Ryzen R5 CPUs demonstrates a clear issue with Ryzen CPUs in gaming. What's interesting though is that the charts include results for the 7700K and R5 1500X both at 3.5GHz. In general tests the 3.5GHz 1500X is roughly as fast as the 7700K at 3.5GHz, beating it in a some tests. In games on the other hand the 3.5GHz 1500X does very poorly compared to the 3.5GHz 7700K. Here's the link: So what's the cause of this? Well... I've done some research and I think I've found the root cause of this issue. It's the huge CCX-to-CCX latency in all current Ryzen CPUs. Modern game processes spawn several simultaneous generally-interdependent threads that share data and migrate across CPU cores all the time. Having massive delays when one thread is crossing to the next CCX or trying to access data that resides in the shared cache of other other CCX is extremely inefficient in this type of workloads. Here's another video that highlights the issue with cross-CCX latency and it's relation to CPU draw call performance.
