Tests provide evidence that the latest Apple laptops using the new NVIDIA chipsets now offer GPU-accelerated h.264 video decoding for the first time. Previous versions of OS X apparently did not take advantage of this capability.

A playback of 1080p high definition trailers from Apple took far less CPU time on his new aluminum MacBook (28% CPU) as compared to his old MacBook Pro (100% CPU). Both computers shared the same CPU speed, but the new MacBook includes the NVIDIA 9400M integrated graphics chipset, while the old MacBook Pro uses the NVIDIA 8600M GT.

This suggests that the version of Mac OS X on newly released “MacBooks, MacBook Pros and MacBook Airs” based on the new NVIDIA chipsets now offers GPU-accelerated h.264 video decoding for the first time. While Apple has previously included graphics cards (such as the NVIDIA 8600M GT) that have contained hardware support for h.264 decoding, the company has apparently not previously taken advantage of it.
