AGEIA PhysX Demonstration Video- WOW!

r520 can already replace the PPU

AEGIA might have a run for it's money if ATI has anything to say about it. One AIB commented today that the idea of a dedicated scalar mathematics processor for game physics could already be replicated on ATI's R520 series silicon, although drivers for such a project only exist in R+D departments (the vendor wouldn't let us have them, we tried). The idea of offloading math to a GPU is not a new idea; many projects exist for Linux for this already. However, the indication we had was that ATI could actually do physics calculations on the card with the graphics processing simultaniously -- the bandwidth is already there. AEGIA's physics processor has already been delayed well into Q2 next year.

UPDATE:

Havok to compete with AGEIA for physics

many have heard of AGEIA and its startling announcement: they will produce a processor used exclusively to process physics related computations. Called the PPU, or Physics Processing Unit, its role will be to offload highly intensive mathematics such as realistic water movement, realistic character physical reactions to objects and the world, from the CPU to a dedicated processor. This all seems like the natural progression of things, since dedicated sound, network and other processors are commonplace.

Today, however, most processors spend their time mostly idling - you're rarely ever pushing your hardware to its limits consistently. Thus Havok, a company that's well known to game developers, has announced that it has plans to do for you what AGEIA promises, but save you money and maximize your dollar spent at the same time. Indeed, Havok has confirmed with us that they are competing with AGEIA.

The Havok FX engine is what Havok claims will provide the functionality of a PPU, but its approach is entirely different than AGEIA's. What's special about Havok FX is that it's a software engine that is currently based on Havok's widely used physics engines. However, Havok FX is designed to offload many intensive physics functions from the CPU to the GPU. Using technology available in Shader Model 3.0 and beyond, the Havok FX engine will be able to take advantage of unused resources of today's powerful GPU's and put them to use.
