AMD talks up its first Fusion chip

[BrowncoatGR]

In my opinion, they are just referring to their visual computing breakthroughs by breaking the 1 TFLOP barrier.

They clearly wrote 1TFLOP GPU, not 1 TFLOP APU ;-)

Furthermore, think about the memory limitations ... ~800 Shader cores and then dual channel DDR3, which is shared with the CPU cores.

That would be not feasible in my opinion.

How the GPU access memory is still an unknown really. But the GPU is made on a 32nm SOI process, so higher clockspeeds than in earlier designs might be achievable.
