Apple’s own QuickTime on Snow Leopard only makes use of H.264 hardware acceleration with a single graphics card: the Nvidia 9400M. If you don’t have that graphics card in your Mac, you don’t get H.264 hardware acceleration, period. Seems very surprising if H264 hardware accel is not also supported by the 9600M GT (which is an upgrade on some models of the MBP).

Those MBPs have a 9600 in addition to the 9400.

  Right -- but as far as I know, switching between the 9400 and 9600 requires logging out. Seems strange if you'd actually see worse H264 performance using the 9600 than the 9400.

    The 9400 is still active when the 9600 is; you can use both at the same with with OpenCL for instance. And I'd imagine that there's only one video decode ASIC between the two of them, no need to uselessly duplicate hardware.

      Interesting. Thanks for the info!
