Titan v 690

[John Hamlik]

Yep, current version. He is a screenshot of after effects GPU panel as well…

We are looking into this as well. We have managed to run a GUI GPU + 2 GTX 690s in a Cubix chassis as well as 5 GTX 680s (1 GUI + 4 GPUs in Cubix).

So far we have not run into any issues. But we are still performing tests and will let you know what we find.

Thanks,
Anish

Great news Anish. Are you seeing performance improvement? And are you on a 2012 Mac Pro?

So based on comments from Anish and Rohit, I tried two 690s (4 processing GPUs) in a Cubix in 2010 MacPro again, this time doing an SMC reset, and jackpot! It seems to be working fine. All the cards show up and I’m getting playback, OS seems solid. This is pretty huge.

Great news, thanks for sharing guys!

Curious as a fellow 2010 MacPro 12-core user, with or w/out a cubix4 what the ‘highest’ build specs will be moving forward?

Titan or 690 depending on whether one does or does not have a cubix?

Thanks again for the news and research everyone.

Presently the best performing config for Mac would probably be 4 GTX680 4GBs in a Cubix. 690s are two slightly slower 680s sharing a card.

curious to see how much of a hit the 2GB (per GPU) 690 would take on 4k footage vs the 680 cards with 4GB of RAM.

4 GPUs in only 2 slots is incredibly tempting though. or a 690 card in a Mac Pro with a separate GUI card. thats a lot of power without needing a Cubix

What about the Titan card…theoretically speaking if its going to work in 10.8.4, wouldn’t that yield better performance over the 680?

John,

Do you use the 680 and the 7950 with a cubix or can they both live together in a MacPro?

I am looking to replace my old 120/285 combo and trying to see what are the best performance/cost at the moment.

Looking at slot requirement, I am not sure it leave space for BM card and any storage card.
Is my best bet is the 680 for GPU and 4000 (single slot) for GUI ?
