Most efficient NVidia card?

post #1 of 5
Thread Starter 
I'm putting together a folding rig and I'd like to toss in a few NVidia cards for CUDA. Would any of you know which of the 200/400/500 series are the most efficient in term of watts per cuda core? Thanks.

Are you looking for efficiency in terms of cuda cores/watt or in terms of folding performance per watt? For the cuda cores you should have all the info you need just by looking up the various cards on the Nvidia website where it will list their cores and their power draw. For folding you could use either this GPU PPD list or I could just tell you that the 450, 460 and 560 are about the best in terms of PPD/watt but they still fall behind a decent CPU in terms of PPD/watt.

watts per cuda core? GTX 590 :>

Also, according to guru3d, it consumes about 70 Watts less than a GTX 570 SLI setup eventhough preformance is almost identical: http://www.guru3d.com/article/geforce-gtx-590-review/7

If you're building a new rig, you should consider a 2600k or a 3930k rig.
But for the GPUs, I'd say 450, 460, or 560. wink.gif

A dual XEON 5650 can cook any single 2xxx and 3xxx i-series CPU simply because I'd have total of 24 cores (6 physical + 6 virtual cores per XEON x2). biggrin.gif Plus the mobo I got with XEON has total of 7 slots and could accommodate 4 double wide video cards. I was trying to get the most out of those 4 x16 slots without needing 2 1kw PSU just for the video cards.
