60 fps isn't much of an issue for 4 core 8 thread Haswell and up CPUs at the moment providing you've paired the CPU with fast memory and it's at 4GHz+
There are already some games - like Dishonored 2, Watch Dogs 2, and Deus Ex: Mankind Divided - which struggle to stay above 60 FPS at all times on a 4c/8t i7.
It's looking increasingly likely that newer games will start requiring at least 6c/12t if not 8c/16t to stay above 60 now.
The only question in my mind is whether Ryzen have fast enough per-core performance and memory bandwidth/latency to manage this, or if it will still require an Intel CPU.
Yes, single core performance within 10% of Intel's top line. 6 and 8 core processors will be mainstream priced, and comparable processors between the two are going to be 150+ cheaper in most price points.
I mean, that's not strictly true.
Intel's top of the line performer for single-core performance is an i7-7700K which has 4c/8t and should hit 5GHz+
I really can't see Ryzen's overall per-core performance being competitive with that.
It will be interesting to see how Ryzen performs in games like ARMA.
People are comparing Ryzen to the 6950X, which is Intel's
most expensive non-server CPU, but one which sacrifices single-core performance and clockspeed for better multithreaded performance with 10c/20t, which is two architectures old at this point (Broadwell) and priced so high simply because there was no competition.
It's fine to look at this and say that Ryzen is better value than Intel - that much is certain.
But it doesn't necessarily mean that Ryzen is going to beat Intel when it comes to gaming performance - where the 7700K is on top for the majority of games, not the 6950X.
If Intel release a 6-core Coffee Lake chip at the same price or less than an 1800X, that's almost guaranteed to be a better performer in games.
Intel has CPUs that are more or less exactly that.
But only on their enthusiast platform.
HEDT chips are more than just the regular desktop chips with more cores in place of the iGPU. They're much bigger dies, and are basically server parts with a few minor changes.
But I do hope that Ryzen pushes Intel to release consumer CPUs with more cores in place of the iGPU.
Exciting times ahead.
