Hi, anybody of you ever thought of adding a physic coprocessor for gaming?
Since you aquired ATI it shouldn't take long to add such a feature.
Just put the graphic chip in (and dont use it as a grafic card as you had in mind with the new portable CPUs)

Not exactly a coprocessor, but both AMD and nVidia(?) have 3 pcie slot configurations coming out in which you can use SLI or Crossfire, then add a third card just for physics processing. Should be interesting. Also there are the Ageia things...

When its on a video card, probably ageia but right now it cant compair just due to being on pci bus. Integrated will be so much faster. Specially when teamed up with wicked fast gpu and mem. They can def get them working together faster all on one board. But you loose the physics everytime you upgrade video that way. Guess you cant really win.

at the moment i wouldnt get a physics card as very few games utilzes the performance. on untill more games use it will it start to populated and become popular

With AMD's upcomming "fusion" chip, I you could use the onboard video for physics processing and leave your descrete chip to do the graphics. In a stream computing situation, there would be far more bandwidth allowing it to function as an x87 coprocessor.

For the physx card, I'm not sure if it will ever catch on. Ageia has created a fantastically powerfull physics engine that runs entirely in software (aka not specific to their physx chip). Their PPU only comes into play when the processing of certain features is offloaded from the CPU. Given the skyrocketing power of the CPU, the advent of stream computing, and the physx engine's amazing abillities, I think it's only a matter of time before ageia drops the physx card for the overabundant and increasingly general purpose power of the GPU.

How many games will use and need a physics card to improve play. When will the physics chip be on a video card.

that would be much better if it was on a video card

It would add a few hundred to the adapter.
