Does the ATI HD2900s and the nVidia 8800s have an actual PPU? Or is it the architecture of the GPU that allows the cards themselves to do physics.... er, can the cards actually act like a PPU is what I'm really trying to ask. This is what I pulled from both ATI and nVidia websites. However, ATI's site doesn't look as clear as nVidia's site does.
ATI Unified Superscalar Shader Architecture
- Physics processing support
NVIDIA Quantum Effects™ Technology
Advanced shader processors architected for physics computation
Simulate and render physics effects on the graphics processor
I remember reading something about how ATI can go into crossfire and have one card do graphics rendering while the other do physics, or have two cards doing graphics and one doing physics. But as far as nVidia goes, I don't know. I'm guessing nVidia can run single or SLI and the card itself has enough GPU power to calculate the physics itself.
Anyone care to shed some light on this?
