someone already did the test with octane in such a gpu?
those who possess a place of comparative performance of the 580 vs 680

no, we are all waiting for that ;) in the licensed user forums are already a few threads spinning around kepler, and if you search the web for benchmarks you will find some not very promising numbers with opencl benchmarks. so we still have to wait and see how well mere cuda apps will perform...

Linus from NXIS tested this card and make a lots of comparison between 680 and 7970 and you'll see this card sure pass 7970 in most of the cases.

Go to his channel here http://www.youtube.com/user/LinusTechTips?feature=watch

EVGA had GTX680 Hydro Copper Classified version in 4GB ram but not at this time.

God loves this card.

i love the cat-play part most ;) the rest is games, games games, but still no cuda testing (not even opencl or directx dc). well, no surprise, its a gamer card in first place...

I really Hope nvidia didn't cut the Cuda capabilities and offer them on quadro only. It would make sense to do so.

I think Octane users are safe.
Looks like 1.5x performance for us.
Double precision apps will perform poorly for Kepler Geforce though.

Ok Guys.

Just picked this snippit of info out for those running out of textures on a scene

Quote

Now that the number of texture units doubled, NVIDIA also changed the way how Texture Units operate. In the pre-Kepler era, you could use up to 128 simultaneous textures. Bindless Textures are probably the key reason why Samaritan can run on a single card, and why the performance of GT 640M and GTX 680 is where it is. This feature increased the number of simultaneous textures from 128 to over a million. Yes, you've read this correctly. An engine developer can now run its shader code on all the textures he or she plans to use and run those textures as they come along. In ideal circumstances, Samaritan demo can address operations on 200-300…1000 textures and Kepler gives you that level.

:shock:

I picked it up out of this review

Interesting

Texture problem solved ? :o

Hundreds of textures...that would be nice...provided you have the vram for it.... conveniently we have a 4gb option this time :geek: 8-)
I am not disappointed by Kepler so far. Hoping the 660 and 670 are decent cuda performers too. The good thing about the die shrink too is the cards are shorter (0.5" for 680) so if you have a restricted case like mine there are more options.
All we need now is Octane built for cuda 4.1 and tweaked for the extra textures - assuming its true - (and with transform and instances of course!) and gpu rendering will really power ahead.
I vote we send Terrence to the US to buy a few for testing. He can afford it and he doesn't seem to be doing anything ATM :P

whoa - great find. this together with 4gb cards alone will make it worth the buy, if octane performance is just as good as with 5xx cards. used 3gb gtx 580 anybody? :D
