ATI has a running system with 3 X1900XTX cards running with 2 running in
Crossfire mode and one doing the physics calculations in one of the private
rooms and there are several Havok FX demos installed to show the power of
physics calculations on ATi cards. The system is running off Conroe 2.66GHz and
Intel D975XBX board on x8 /x8 /x4 PCI-E configurations as well as a 1KW
PCPowerCooling PSU.

There is also another system running with 2 x X1900XTX cards and 1 x X1600XT
card on ATi RD600 chipset on x8 /x8 /x4 PCI-E configurations. It is also
possible to run on mismatched cards for eg. one X1900XTX paired up with one
X1600 or X1300 card with the former doing the rendering and the latter doing the
physics.

VR-Zone has the opportunity to talk to the VP of the ATI desktop
graphics dept and learn more about this new technology. He revealed that the
X1900XTX delivers 9x better performance than the AGEIA PhysX card and X1600XT is
twice faster. The speed of physics calculation depends on two main factors; core
clock and parallel pipelines and the reason why GPU is much faster than CPU in
physics calculations is due to the fact that GPU is capable of data parallel
processing. Apart of Havok, ATi is currently in talks with AGEIA to include
their API as well.
