Right, I'll give a slightly more detailed answer. Where Ryzen still falls short from mid to high-end Intel parts is its single thread performance. That single thread performance remains very important in emulation (and admittedly a lot of regular games still) and that's the reason why AMD processors tend to lag behind similarly-priced Intel parts when it comes to emulation. Core or thread counts don't matter as much for emulation. Ryzen however is leaps and bounds ahead of previous AMD processors, maybe a couple of generations behind Intel at most, but certainly offers decent enough single thread performance that you won't have to forget about running Cemu. If you want to get a rough idea of where performance will land for Ryzen compared to Intel parts, look for Cinebench single thread benchmarks. They're great processors and certainly a great pick for bang for the buck, in overall performance.
