I knew Sony was confirmed still the same. I mean the cpu performance has hurt games it's been shown that the higher clocked Xbox had better frames in games than the ps4 so some games definitely still are cpu bottlenecked.Consoles don't need high perf CPU when their API has lower CPU overhead and well threaded. Sony's documents to devs with the leak specs have it as Jaguar 8 core at 2.1ghz from 1.6ghz.
The only market that would benefit from high IPC APU of Zen + Polaris would be HPC, Servers and Enthusiast gamers who want mITX rigs.
Throwing a much faster gpu now means games will even be more cpu bottlenecked or they'll have to really start utilizing the compute power of these gpus.
