I know there has been some talk of PS3 tech-wise here recently, but I thought it'd be good to have a general comparison thread.
I was wondering what Xenon's architecture was looking like, and how they are sharing the graphics workload? Xbox was simple CPU for housekeeping, running the game etc, and big ass GPU doing the polys.
But Xenon apparantly has 3x2 3+GHz processors in it. Thats way too much for simple game logic, so are they using a similar model to PS2 - having the CPU do the transformations, and the GPU is just shaders/rasteriser? If so, does this mean a big leap from 'traditional' PC parts, and therefore any past performance in no indication of future performance?
What advantages/disadvantages - removal of transform leave lots of on-die space for edram/more shader pipelines, but then you have external bus bandwidth issues
