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)...

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.

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.

So far not a single rumor has said anything positive about Xbox 720 over PS4. We've heard consistent rumors that Wii U was underpowered/not a true next generation console on the hardware side and that proved true. Is it a coincidence that nearly every rumor out there is claiming PS4 is a superior console on the hardware level than Xbox 720? If MS plans to integrate Kinect 2.0 into every console, unless they take larger losses on the hardware, they have to cut costs somewhere else. If MS chose Kinect 2.0 in hopes of targeting casual gamers/making it a stand-out console feature, they have less $ left for a powerful CPU+GPU setup.
