Kepler lineup

[tehfailsafe]

From stuff I've read around the internet so who knows...

There is also the gk110 chip, which I think is what we all expected out of kepler. I think the current chip maybe they planned to be a 660 version but since it outperformed the current AMD lineup in gaming the launched it as the 680 top of the line card to get the higher pricepoint. Then they are probably holding back the 110 somewhat to create demand when they launch it as the 685 or 780, which I hope will have much better compute performance as well.

Here's hoping we don't have to wait another year for it and they launch it like Q3...


But I still have a little faith in the 680, let's see some octane tests!

Good work guys, thanks especially to T_3 for trying to benchmarking it.

It would be really nice if somebody from the core team, if not Radiance himself found bit of time to write few lines here, what can we really expect performance-wise, surely they have some idea by now.

I will just wait and not buy any new GPU if Octane is also slow. I also think it will be a long time until a Octane build for the 680 is coming along due the acquisition.

And if Nvidia makes it true and only serves GPU computing to quadro users I will switch to nvidia and another GPU renderer which supports ati cards....I'm a long term nvidia user but I'm not willing to support this product politics!

I do not think they would do it, i mean kill potential market like this. If gtx680 will turn-out insufficient in terms of Octane/single-precision gpgpu computing, i am sure this will be solved with upcoming "big Kepler" chip, possibly called gtx780 or something like that. Taking any meaningful gpgpu capability off Geforce completely would lose them lot of potential buyers, not only CG artists, architects and designers like us, but many people who "crunch" with their cards some BOINC stuff. These would definitely not buy expensive Tesla for such non-profit activity, they would just turn to AMD.

Anyway, i hope for dual processor "big-Kepler" card, at least 3x as fast as my current gtx590 for similar price (i paid for 590, although i would not mind cheaper ) I would definitely buy that and i am willing to wait another year. I do not have this card not even whole year, so right now its too soon to upgrade anyway.

& there is still a lot things that need to happen driver- or app wise. kepler is a brand new design, a lot different from the last two generations, so it'll of course need some time until it will be possible to use it's full power for more uncommon scenerios like unbiased renderers; or this here: http://forums.nvidia.com/index.php?s=cb ... &p=1386517
last but not least the gtx 680 is meant for gamers in first place - because mass market is of course paying nvidias bills. we'll wait and see; and stack up some more 580s in the meanwhile

I just got 2 GTX 680's and installed them but for some reason they are not working with Octane Standalone and Octane plugin for Max. The render progress window does not go anywhere and the GPU's are not being used at all. I am monitoring them with the EVGA Precsion X that came with the cards. I have NVIDIA Graphics Driver 300.83 installed which is what came with the GPU's.

In Octane Standalone it shows that both cuda devices failed. Is this maybe because these are CUDA 3.0 devices and the 580's were 2.0???

I was super excited to try these out. Hope to get them working soon so I can report the performance results with Octane. Has anyone else successfully rendered with Octane on GTX 680's??

Thanks!

bad news...

new hardware + new drivers + new Cuda + new Octane

...too much variables...

[mbetke]

This would be the perfect time for an offical statement from the Devs here if they work at the moment for a compatible build, if too much stuff changed to Cuda 3.0 or whatever happenend behind the scenes. Maybe noone works on Octane at the moment.

Just one sentence would be enough.

[pixelrush]

It may be a while before Octane runs on GTX680 just for practical reasons.
I think they will probably want to get the next jump in code - instances and such - out while sticking with cuda 4.0 and then when things are stable move up to 4.2.
I know it would be nice to have Octane run on new hardware immediately it comes out but they need to keep their priorities and keep development orderly.
It will be here soon enough.

[matej]

Then an official warning should be in order: don't rush to the store for a 680 just for the sake of Octane, cause it wont work still for X months




(Wait for next gen. Kepler, the next Octane version will come about the same time)
