I think looking at all the games overall these two are pretty even, Intel win some and Ryzen wins others, Metro LL is a pretty big performance gap with for Ryzen tho.
On that alone Ryzen is clearly the better gaming CPU but further in the video yes the 6600K does spend a lot of time with all its threads at 100% and the stuttering its causing is horrendous. some might argue thats because its deliberately setup to be completely CPU bound and at 1080P its wouldn't happen, and yet mainstream reviewers have always benchmarked CPU's in this way, their argument being that as GPU's get faster those results would become an issue for the users of the weaker CPU, so with that in mind the i5's just can't cut it, clearly the way to go is 6 cores, the Ryzen 1600.
I've been playing GTA5 a lot recently and I play at 1440p on my 4670K and still get quite a bit of stuttering. Would love to upgrade but I'll wait til Zen+ I think.
