Seems like the Nextbox have "special sauce" units to help and free up the GPU... so less work to GPU... in the end the performance is near the PS4.
It's like that...
PS4 power: 5 task per cycle
260 power: 3 task per cycle
You have to run 5 tasks in both GPU but the Nextbox can do 2 tasks in the "special sauce" units... so at the end both give you the same performance. Of course that a dummy example lol... and these tasks are not for graphics at all (it is but not shaders specifics)...

Another point is that PS4 will reserve only 896 shaders units (1.4TFLOPS) for graphics... the others 256 shaders units (400GFLOPS) will be free to developer use for anything (graphics, GPGPU, etc).

I already explained to you why this makes no sense. All the shaders in HD7000 are the same. Sony does not need to use different shaders since they don't care about BC with PS3 on a hardware level. If you had 2 arms, would you only do push-ups with 1 arm? If you have 1152 shaders, you can use all of them. Unified shader + compute architecture of Graphics Core next allows ANY shader to do compute or graphical work. You do not need to "free up" 256 Shaders for GPGPU tasks. This is not how game code works.

At the end what will show how good the console perform is the optimizations and full use of the hardware. |
Ya and PS4 seems to be easier to code for/optimize directly to the metal of the hardware and supposedly has a lower OS overhead based on comments from developers.

the article says microsft is investing heavily in motion controls, has weaker graphics then ps4 and no used games support, if true i hope microsoft fails nextgen, sounds horrible.
