What I don't get:
Why are you ignoring the GPU in AMDs A8-3850 APU? It's called HD 6550D and is capable of delivering 480GFlops (with fast enough memory, like e.g. GDDR5) at it's base clock (which is a lot lower than what is possible because in PCs where this APU is typically used the DDR3-RAM is too slow and so they cut the power of the GPU down; but there's no problem to apply a 20-30% higher clock to it -even 50% is possible but that may result in too low yield rates or too much power consumption).
So you have at least 480GFlops to add to the PS4s graphics power.

People have been looking at this "hidden crossfire" setup and even with best conditions (with a 6670 GPU), the whole AMD idea - when run on a PC architecture - turned out more or less as a complete dud. You get around 10-15 fps if you want 1080p. Granted an imaginary PS4 setup with 1G UMA and no windows driver interference, 1866MHz memory, will fare much better, but stable 30fps at 1080 would be extremely difficult to achieve.
And forget pumping up clock rates, the A8 already burns through 100W at 2.9GHz.
