The latest MacBook Pros offer “hardware acceleration for H.264 video playback,” Arnold Kim reports for Mac Rumors.
“While Apple has previously included graphics cards that have contained hardware support for H.264 decoding, the company has only recently taken advantage of this hardware acceleration. Mac OS X Snow Leopard’s specs officially acknowledge this support but it appears to be limted to the NVIDIA 9400M graphics processors found in recent Apple laptops and desktops,” Kim reports.
“Unfortunately, it does not appear that this support will extend to older video cards,” Kim reports. “Hardware decoding of H.264 video improves the performance of video playback while leaving your computer’s CPU free for other tasks.”
