[citation][nom]therabiddeer[/nom]Well, they mention that there is an enhanced GPU and I dont know of any APU's that come even close to a 7850 in performance, so its likely an APU and a GPU (they also mention parallel processing, which is what that would involve)[/citation]
It's a custom APU. From what I've read, they basically integrated a Jaguar CPU into a Pitcairn-like GPU.
Also, modern multi GPU gaming is actually not using multiple GPUs for enhanced parallel processing, at least not in the way that the word seems to imply to me. That would be splitting a frame between the GPUs whereas modern multi-GPU technology lets each GPU take turns rendering entire frames on its own. Maybe that still counts as parallel processing, but it's not what the phrase seems to imply to me. I think that they were just throwing that term out there for work between the CPU and the GPU.
