That still leaves every other capable piece of hardware out in the cold.Hardware acceleration for H.264 under OS X requires the 9400M, as you can find out directly from Apple.
The 9400M G gets love but not the Mac Pro?

What hardware decoding of h.264 is on the Mac Pro?Mac Pro gets some love too
Would you please elaborate?...but realistically 9400M is probably a bit better.
Touché, Eidorian!
According to http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units
the GeForce 8800 GT computes a whopping 504 GFLOPs
where as the GeForce 9400 GT kneels down with a mere 67.2 GFLOPs
That's for raw computing power (do I hear CUDA, anyone?)
As for the video decoding API support;
-the 8800 has PureVideo 3 with VP3, BSP Engine, and AES128 Engine
-the 9400 has PureVideo 2 with VP2, BSP Engine, and AES128 Engine
Hows that for a DOWNGRADE hidden behind the product naming?
It has been all about selling "new" features for years now.
I love's UI and design, but I'd like (as a Technically Savvy Person) the software to bee in par with the hardware.
Microsoft actually has been more open about GPU video decoding (and encoding, for that matter) in their operating systems, because Microsoft's revenue doesn't involve selling hardware as much as Apple.
You obviously dont know how naming schemes work.
Of course a High End 8800GT is going to be better than a low end 9400GT. Hell Im pretty certain a 7900GTX will outperform that 9400GT.
The only thing this post proves is your lack of knowledge.
Mac Pro gets some love too, but realistically 9400M is probably a bit better.

http://ryan.plexapp.com/?p=34The new version of Quicktime uses NVIDIA’s VP3 (Pure Video 3) API for hardware acceleration of H.264 video. This is currently only available on the 9400M GPUs in Macbooks and Mac Minis. The actual hardware is a separate decoder chip on the board, not directly using the GPU itself. This differs from OpenCL, which aims to use the GPU as a general-purpose CPU, and is not well suited to video decoding.
Unfortunately the API is only available when using QTKit, Apple’s new Cocoa framework for Quicktime. This means the support is limited to formats QuickTime X supports, which for our purposes isn’t particularly useful. Installing Perian helps by allowing MP4/MOV with AC3 audio to play, but MKV support even with Perian is pretty poor. Surround sound isn’t very well supported either, although future versions of Plex will have the capability to take multichannel sound being played through Quicktime, re-encode it to AC3 and send it to your receiver, in much the same way as the AC3 encoder works now. This may change if Apple broadens the API to allow acceleration of raw H.264 streams.
The other difficulty with QTKit is that rendering is only possible to a QTMovieLayer or a QTMovieView. This makes it incompatible with the current video player in Plex, so QT X support needs to wait for our new player, and is not an ideal solution for all video.
Does that have anything to do with the fact that a lower end GPU is supported to decode h.264, but the higher end is not?
The facts remain the same. Don't discredit them.
By the way, i was referring to a post;
But of course, I understand that discrediting is important to some
The higher version number actually fools most people. It never fooled me.
Many GPUs have video acceleration since years:
nividia -> pure video: http://en.wikipedia.org/wiki/Nvidia_PureVideo
ati -> avivio (hd): http://en.wikipedia.org/wiki/ATI_Avivo
Windows-Users have DirectX Video Acceleration (DXVA). So everyone can use the video acceleration.
Without QTKit you can't do anything on the mac.
