But you would be suprised for a console coming out over a year later its not that much faster.
GPU=1.80 TFlops for both Pixel and Vertex Shaders
GPU=0.88 TFlops for Unified Shaders=1.75 TFlops for combined Pixel and Vertex Shaders
So the PS3 has a total theoretical of about 2 TFlops and XBox 360 has about 1.9 TFlops (counting Pixel and Vertex shaders separately, as thr PS3 does).
Sony could be in trouble, when the ps3 is out and xbox 360 has dropped to $200 dollars are you gonna pay $300 more for 0.1 teraflops?
Edit: read more of the thread and you will see the xbox 360 is more than likely faster.
