The AGEIA PhysX processor is the critical hardware element required for optimized game physics and is the third engine of the Gaming Power Triangle which will drive a new era in exciting and immersive gaming. This new triangle consists of the central processing unit (CPU), graphics processing unit (GPU) and Physics Processing Unit (PPU) working together to balance the extensive computing demands of game logic, graphics and physics. Within this balanced triangle the CPU “thinks and orchestrates” to drive game artificial intelligence and logic, the general purpose GPU “renders and displays” to deliver beautiful 3D imagery, and the third leg of the triangle, the new AGEIA PhysX Processor, “moves and interacts” to take gaming to the next level with pervasive dynamic motion and interaction.

Website is kinda big, so dial-up you might want to go get sandwich and a drink.
