CPU Requirement

I understand it’s a bit early to know for certain what CPU is required to play all games on RPCS3 with the internal resolution cranked up to 4K, but hopefully there is enough insight to know the answer.  Basically I am wondering if an i7-7740X running at around 5.1 to 5.3Ghz with or without hyperthreading would be enough CPU power to drive games at 60fps (patched if normally a 30fps game).  Or if an 8core CPU is required, possibly a release a few years down the road when the CPU is faster than what is available today?  I’m not worried about necessary GPU power cause it’s much easier to pop in a new GPU than a CPU.

Games of interest:
God of War 3
Demon Souls
Red Dead Redemption
Uncharted Series
Ratchet and Clank Series
The Last of Us 
Infamous Series

Most of those games don't run so we can't know yet, but 7740X @ 5.1GHz should be enough.

Are there any plans for implementing avx-512 in future builds?
