VC-1 playback

Similar to the AMD 780G, AMD 790GX supports hardware decoding of VC-1, H.264, MPEG2 with it's UVD technology that was formerly available on discrete graphics cards. With it, you can offload the CPU and let the chipset handle the decoding.

We tested two HD-DVD discs, the first is the The Bourne Supremacy and the second disc is the HQV HD Test Disc. Both titles are encoded in VC-1 format playback using XBOX HDDVD drive.

Results

With the disc Bourne Supremacy, the AMD 780G records a CPU utilization of around 15% with a X2 5000+.

With the AMD 790GX board with Phenom 9550, the CPU utilisation is around 8.7%

On AMD 780G running the the HQV HD disc, the CPU utilisation is even lower, we achieved an average of 9%. On the AMD 790GX with a Phenom 9550, it only utilitised 6.175% of CPU to playback the clip.
