Required Graphics Cards for Snow Leopard

Apple’s Snow Leopard page has revealed some details about hardware support for the H.264 acceleration and Open CL.

The latest MacBook Pro’s offer hardware acceleration for H.264 video playback. While Apple has included graphics cards that have contained hardware support for H.264 decoding, the company has only recently taken advantage of this hardware acceleration. Snow Leopard specs have support but it seems to be available only to a limited number of graphics cards. It does not appear that this support will extend to older video cards. Hardware decoding of H.264 video improves the performance of video playback while, at the same time, leaving your computer’s CPU free to do other tasks.

Here are the list of GPUs that will be supported for the upcoming hardware acceleration and OpenCL:

-NVIDIA Geforce 8600M GT, GeForce 8800 GT, GeForce 8800 GTS, Geforce 9400M, GeForce 9600M GT, GeForce GT 120, GeForce GT 130.

-ATI Radeon 4850, Radeon 4870

Some companies have found a 5x speed increase in video encoding when using OpenCL-esque technology
