I have known this for a long time. I guess people take numbers and run with them and I get why they do, but as I said before this is what is really going on......
The PS4 is like a lower mid-end PC and is mainly off-the-shelf PC hardware. Some things have been modified a bit like GPGPU and other things, but it's 95% of an off the shelf PC.
The PS4 architecture is pretty straight forward and simple design and you will see some big performance gains over time, but the XB1 will have those too.
The Xbox One is 95% non-off-the-shelf PC. With only a small part of it being off-the-shelf. The Xbox one GPU isn't as powerful as the PS4 on paper.
This is fact and it is a fact that most people fall into the trap of believing paper numbers over real-world performance.
1) The Microsoft architecture is more efficient than a normal PC architecture. Microsoft made D3D 11.x, they know all about it because they created the entire API. They optimized the "XB1 mono driver" for performance.
2) The XB1 can offload processes to other processors and can also do GPGPU, but it's not required. The more PS4 uses GPGPU, the less they use the GPU for
graphics processing and they have to do this because they don't have the processors that XB1 has. The PS4 has more Compute Units dedicated for GPGPU features, but again the more you use of the other CUs the more things can suffer.
3) The ESRAM can be a little more flexible than what Sony uses the GDDR5 for.
I really never even mentioned any performance increase (53 Mhz GPU boost or the 150 Mhz CPU boost either)
I also haven't actually mentioned the "server processing" yet, which will come later. Halo 5 will probably be the first title that really uses this and people are going to be fascinated by what is coming.
