ATI Stakes Claims On Physics - GPGPU Ground
We linked to a story from X-bit Labs last week detailed that ATI's GPUs are capable of physics processing. The Tech Report expounds a bit on that revelation with some commentary on a physics demo that ATI ran at the introduction of the X1000 series:
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.
