I'm in a dilemma.
For a 2009 MacPro i need a new GFX board; needs to be official native mac,
so EVGA GTX680 2GB Mac or Sapphire Radeon 7950 3GB Mac (no K5000).
It should be used with FCP-X and Resolve (Le) v10 in HD.
Available Benchmarks are not that significant.
variables to consider:
- In Resolve v10 both seem to have nearly the same performance.
- In FCP-X 7950 seems a little bit faster
- BMD recommends more than 2GB for HD + optical flow + effects in v10,
so 3GB are definitely better than 2GB;
but would 680' processing power compensate lack of VRAM?
- Apple comes up with a new OpenCL; so what gain is to be expect from this?
Please do anyone have got real-world experience comparing both?
Which board 'behaves' better?
What would You suggest?
(I wished EVGA hat put in 4GB to Mac Edition;
the decision would then be a no-brainer.)
Rather than listing all thinks if you look at about March 19 forward you'll see many tests http://barefeats.com
I'd have to ask have you considered looking at the 2012 iMac with the 680MX for comparison. I suspect in some cases the Quad i7 Ivy Bridge may be comparable to certain 2009 MacPro configs given the advances in chip technology. You don't mention which 2009 MacPro you have (4 cores, 12 cores?) but that can be a big factor.
If you're using it for Resolve I'd stick with a pro card like the Quadro K4000 or whatever your budget allows - while the gamer cards are very fast, both AMD and nVidia purposely cripple the cards for 8bit output only. Using a Firepro or Quadro gives you 10 bit possibilities if that's important to you - of course you need a 10 bit display.
