GPU benchmarks

[Valtiel]

The double precision rate of consumer Kepler cards, excluding Titan, is actually artificially hamstrung. A 780's DP rate is 1/24 of its single precision whereas Titan runs at 1/3. It's not just a RAM difference. It doesn't seem like RT uses DP much but you'll see a big difference going to Titan with things like Folding @ Home.

No question there, if you can go without the extra memory, 780 is pretty much the same as Titan. With these cards, Kepler really shows what it is about - huge amount of cores with almost the same TDP as GTX 580. 680 is balanced for games and just doesn't have enough cores for general computing.

Yes, you have right. But I have 780 SC with higher default clock and higher GPU boost.
You are right, if I have a titan, it will be definitely faster cause have a very good case and temperatures is low. But this 780 SC card from EVGA has much better power/price then Titan. 12% for so much extra money is not good. I know, titan has 2x more RAM, but it not so important. For lot of standard scenes 3GB is good. And for some large scenes 6GB is still a few.

[ivaylo.ivanov]

Titan has more cores, but lower default clock, so it sholud be 12-13% faster on default settings. However these cards have dynamic overclocking based on the temperature. If all conditions are the same, Titan will be definitely faster.

I'm still waiting for NVidia, or a 3rd party that tweaks their cards to make an 8GB, or 12GB card. Then I'll start to make the switch to RT I think.

780 Better than titan?! Wow. If only there was gtx 780 with 6gb of ram

[Jiri.Matys]

I sell my EVGA Geforce GTX 580 and buy a new one, so I made a last test with newest drivers before I sell it and a test with a new GeForce GTX 780 Superclocked from EVGA.

EVGA GeForce GTX 580 1,5GB
driver 320.18
CUDA - 2m 39,3s

EVGA GeForce GTX 780 Superclocked 3GB
driver 320.18
CUDA - 1m 56,2s

I think that is good.

previous reply got titan record, titan around 1min.50sec, faster than gtx 780.

Then I should have clarified; faster than *my* Titan

GTX 780 (2min.5sec)

Not bad... that seems better than a Titan.

I have a quadro k5000 card and I'm working if I should purchase the k20 or the new titan? Does Vray take advantage of hyper q or is it a waste to go with the more expensive kepler cards?

Hi,

If it is corrected in 3ds max 2014 why am I now getting the issue saving to PNG files? It was working fine in 3ds 2013...I'm I missing something?

[vlado]

The gamma of PNG files has always been wrong in 3ds Max right from the start until 3ds Max 2013 (the inverse gamma was written into the file) which meant you couldn't open those PNGs properly in any other software that was aware of the gamma. In 3ds Max 2014 this is corrected.

Best regards,
Vlado

All cards are on one workstation with a 4-way SLI board...Just needed one beefy power supply.
Max 2014 seems to be working correctly however I did see some issues with gamma output in PNG files. 3DS Max 2014 made some changes in the gamma input and output settings the option are no longer there it's "Auto" now but I think that is having something to do with it. Jpegs and tiff's are fine.
