I know this news is about the R520 card but the R500 in the 360 is in the same family of this series so i thought it would apply.

ATI practically kicked off its press event for the Radeon X1000 series with a physics demo running on a Radeon graphics card. Rich Heye, VP and GM of ATI's Desktop Business Unit, showed off a simulation of rolling ocean waves comparing physics performance on a CPU versus a GPU. The CPU-based version of the demo was slow and choppy, while the Radeon churned through the simulation well enough to make the waves flow, er, fluidly. The GPU, he proclaimed, is very good for physics work, and he threw out some impressive FLOPS numbers to accentuate the point. A Pentium 4 at 3GHz, he said, peaks out at 12 GFLOPS and has 5.96GB/s of memory bandwidth. By contrast, a Radeon X1800 XT can reach 83 GFLOPS and has 42GB/s of memory bandwidth.

again i know this isnt directly about the the Xenos but it used the R520 as its base starting point.  with all the customization im sure the xenos is actually one of the most powerful cards in the R520 family.  either way its a good read.

Excellent

I find this pointless. If the GPU was used for physics, you would lose graphical detail. Also, we already knew that GPU's did way more Flops than a CPU. Also, I'm sure the tri-core PowerPC CPU does way more Flops than a P4. Last, of course the graphics card has the right mem for physics processing. Guess what the physX cards coming for the computer use, GDDR3...............

i understand all that.  i just figured i would post this news as this is something we didnt know about the card yet and this could mean that IF there was ever a problem with getting the physics to work at optimal levels (like some were concerned some time ago) then maybe the GPU could help out some, not take the workload all by itself but just give a little nudge if need be.  

again it just seemed like a good read
