GPU benchmarks

[vlado]

Get the today's nightly build; I introduced some bugs last week which are fixed now (and it's also a lot faster).

Best regards,

Regular vray render, see the table glass how light it is.




rt gpu



Trace/GI depth in this scene is 20/20

[Paul Oblomov]

Have you tried to increase depth to something above 5 ? I remember set that to 6 - and i was equal.

[Morbid Angel]

Vlado did you notice that the glass renders much darker with RT gpu then regular vray, is there a reason for that?

[vlado]

Gradients and falloffs have been supported since a long time, even in the official builds. Now we have also added support for Color Correction and Mix maps.

Cool!... Vray double sided materials, gradient shaders and falloffs supported yet in the nightly builds?

this is an interesting test. This is a build from last night, and it appears a lot more shaders are supported, note the lamp sss now is working. With that said, the render time on my GTX 480 and driver 306.25 is 5 min 54 sec

Has the GPU code been optimized for Kepler GPUS yet by any chance?

As you can see from the benchmarks, V-Ray RT GPU runs at nearly the same speeds on Kepler and Fermi architectures, while many other renderers work quite a bit slower on Kepler. We still have room for improvement though.

Yeah Even the AA filter

I just made somes tests with 3 GTX :
1 GTX 570 (1280Mo) / 1 GTX 670 (2048Mo) / 1 GTX 680 (4096 Mo)

Results are similar (5%-7% differences between each cards)

With two 580s I did the benchmark in 1:29. Eric did it with two 680s in 1:34. A little over 4% difference.

I have 2 680's 4GB in SLI. works well, from what I understand they are not faster than the 580's, however, they draw less power and run cooler.

Could we get a set of tests with 1 or 2 680s to see how those scale in comparison with the GTX 580? Any GTX 670 user would me more than welcome to contribute.

I am really split between getting a refurbished GTX 580 3GB or a 670 4GB atm. The 580 will surely be faster, but the 670 is much cooler to run, has that extra GB or space and will stress my PSU much less if I decide to add another one (or 2) in the future.

I am curiuos about the 680 as well. I was thinking of going for either the 680 sli or the new and rare 690 if i could get my hands on it. It would be awesome if i could no which setup works better beforehand.

Anyone have one or the other?
