NVIDIA GeForce 8600: Full H.264 Decode Acceleration

Final Words

Although we haven't been terribly impressed with the gaming performance of the GeForce 8600, it is currently the best option for anyone looking to watch Blu-ray or HD-DVD on their PCs. The full H.264 offload onto the GPU makes HD movie playback not only painless but also possible on lower speed systems.

Even more interesting isn't the GeForce 8600, but the $100 GeForce 8500 that we'll be looking at in the coming weeks. According to NVIDIA, the GeForce 8500 will have the same H.264 decoding power as the 8600, so if you don't need the added 3D gaming performance then the 8500 will be an even better solution for HTPCs.

Honestly, the only downside to H.264 decoding with these cards isn't the cards themselves but rather the state of decoding software. WinDVD appears to be ahead in the fit and finish department, while hardware support is better with PowerDVD. WinDVD also performs better on the new 8600 GPUs for H.264 decoding, while PowerDVD is faster on other hardware configurations. Both applications also need serious work before they are useful in Vista 64-bit. We'd expect at least one or two more revisions of the software to go by before these problems really get taken care of.

Kudos to NVIDIA on being first to deliver full H.264 decode assist not only in any GPU but moreover in a mainstream GPU. Now it's a matter of how quickly NVIDIA can extend this functionality to the rest of its product line, and how quickly ATI can respond.
