Re: AMD claims next-gen Xbox will do Avatar-quality graphics
Besides, in order to do Avatar type graphics, there will have to be Ray Tracing involved. Between the processing and bandwidth involved for such a thing, it's not going to happen on the Xbox720. The next Xbox perhaps, but not this one.
Unless we are looking at a freak system with 12 CPU cores, Crossfire, and perhaps several AMD GPUs used in some sort of OpenCL capacity for mega processing power. I still doubt that would work though...
