But since the PS4 is a x64 CPU it means that low level optimizations on a level that seldom normally is considered viable for the PC platform is suddenly "just portable", for example Assembly code for utilizing SSE4 and AVX to a higher degree than now. Sadly it won't have AVX2. About the Windows overhead I doubt it is the OS itself that is taking much power (like disk I/O and kernel), instead it is the possibility of accessing the GPU directly that might give the PS4 an edge here (assuming console and compared PC had comparable hardware power). At least with this gen the PC will share the rewards of heavy CPU-side optimizing which is quite interesting and different from previous gen. In short, specific CPU optimizations done for PS4 and next XBOX will probably make the PC version even faster since the quality of the game ports should raise quite alot. The use of DDR5 is interesting but as far as I know that memory type has quite high latency and the GPU will also steal lots of memory bandwidth, meaning the CPU would need lots of cache to work efficiently in this configuration. I guess we'll see later this year :).
