  Single GPU

  Posted by Ivo Velkov on September 21, 2011 at 7:32 pm

  Hi,
  I’ve got macpro1.1 and it has only 4 slots(3 of them are busy) so i need to run davinci resolve with only 1 gpu.
  Is there someone with experience with 6850/6770 or 5770 video card.
  Or what is the best performanse solution for about 150-200$.
  I need realtime playback mostly for HD 4:4:4 or Prores 422.

  Thanks

  You need to start with a newer Mac pro…

  The 1,1 Mac-Pro has PCIe V1.0 slots and cannot sustain the needed memory bandwidth to and from the GPU for resolve to work and especially not with 1080P 444 footage.

  Try a proper GTX
  285 or 470modded for 300 bucks, you need it anyway.

  Its weird because i can play and capture RGB 444 and Prores with no problem.Only when it plays with resolve i’ve got 12-14 frames with 3-4 nodes.
  I also have decklink 3d extreme.Does resolve use it for some acceleration or everything passes trough gpu?
  Thanks
