  AMD RS780 scores 53fps in DOOM 3 while RS690 scored 30.6fps

  In our ongoing quest, we tested a X2 5000+ running on both a RS690 and RS780 mainboard.
  
  Doom3 was used to test the integrated performance of the GPU. We set the game to run in 640x480 medium quality. With the 1 yr old RS690 (AMD 690G), it scored 30.6 fps. With the new RS780 chipset, it scored 55.3 fps. That is a 80% improvement or 1.8x faster over the old AMD 690G.

  ATI UVD in AMD RS780 requires ~ 10% cpu utiliastion to decode VC-1

  If you have been looking around for a mATX board that can do decoding of your HD-DVD or Blu-Ray. It seems that the AMD RS780 is the way to go In our ongoing test, we took two VC-1 titles (HDDVD) and play it back using PowerDVD.
  
  To our surprise, the average CPU utilisation is around 9% for the HD HQV benchmark disc title 1 and around 15% for The Bourne Identiy, both HD DVD. In the past, only high end graphics cards are able to do that. This is the first time I see an integrated graphics chipset being able to deliver such low CPU utilisation decoding HD-DVDs. Most importantly, the North bridge remains cool to touch!
  
  Stay tuned to OCWorkbench for our full review of the RS780 using the Jetway PA78GT3 mainboard.
