this seems to be were sony was trying to go with the PS3, using a common architecture for gfx and cpu (they were experimenting with having another cell processor and software rendering rather than having a gfx card).
this, i think, is a brilliant idea, and while it is DIFFERENT than current archetectures, meaning it will take time to get used to, it will ultimately be simpler (and hence, more efficient and power friendly). for the ps3, they were trying to turn a CPU into a GPU, for this they will try and turn a GPU into a CPU, but its all just semantics really, it all rides on the common architecture they choose. I mean, in all likelihood they will fail again, but I commend them for trying.
