| ATI's Stream Computing Technology Can Use GPU for Other Tasks |
| Sunday, 01 October 2006 03:41 |
ATI announced a new technology called Stream Computing. This revolutionary new technology allows your graphics card (currently supporting X1900 GPUs) to accelerate time-consuming computing tasks at the enterprise level. Applications ranging from security, weather forecasts, financial predictions, database searching, and more will all see performance increases with the use of an idle GPU. One way this might affect you is physics calculations in video games. Up until recently, no one cared about non-essential physics in a game engine, but now it's really in the spotlight as a way to increase the visual appeal of a game. When things look like they could actually happen, you'd probably enjoy watching them (imagine a game where the tires of a car DIDN'T sink into the ground randomly). We can hope that gaming physics and other similar applications appear soon, to take advantage of hardware we already have. Unlike a CPU, a GPU is built from the ground up with a strong focus on floating-point operations. Floating-point performance is usually measured in terms of Flops (short for floating-point operations per second), and in today's computers we usually see numbers in the GFlops (giga-Flops) range. A typical Core 2 Duo CPU can get around 20 to 30 GFlops of performance, while a Radeon X1950 can give you almost 400 GFlops. The possibilities for this are endless. Programs such as SETI@Home from UC Berkeley or Folding@Home from Stanford are already looking into using your GPU to perform calculations for them. Weather forecasts could predict storms much further in advance, giving you an earlier warning. The list goes on. For more information, see this article.
