Good thread, but pretty much what we already knew. Powerful, but not PC LEVEL.

Should be a beast though. Can the games push it though?

Well the GPU is over actual PC level if AMD deliver what they are talking.

Graphics + Compute in parallel = Two GPU on PC... one for Compute and other for Graphics with the disvantage the GPU not be unified (same shared memory and PCI-E bus to comunicate).

The PS4 GPU seems like 2xGPU... one for Graphcis and other for Compute put to work together sharing the same resourses (Memory, etc) without delay in comunications.

Uh? Where are you getting this magical duplication?

Graphics and compute in parallel means more granularity in sharing the CUs, be that because of the increased number of queues as shown by the VGLeaks diagram of a few weeks ago, or by something akin to hyperthreading in CUs- i.e. a hardware assisted context switching.

The overall global limit is still 1.8TFlops; these improvements will make sure it can be used with an efficiency closer to 100%, but not magically duplicate it.
