The new Cycles GPU 2.72 Benchmark

EDIT: I guess I should learn to read properly. It seems the GPUboss site has done the benchark for video game performance only rather than GPU rendering. According to the comments, only one of the Titan z GPU was used for it as well.

I’ve re-done the bench with only one of my Tb GPUs selected and the time came over twice what the Titan z got. So unless I’m overlooking something, it doesn’t look as if you are actually limited to only 6gb with the Tz as much as others have said.

So disregard the above.

Yeah. :yes:
Well, in Blender I can’t load scenes more than 6GB. The reason for that is because 6GB are associated per GPU. So, in a render, the scene is loaded 2 times (1 per GPU). In practice each GPU in Tz Card have 6GB dedicated. You can see that in the architecture board here (a photo when I was installing the Watercooling in it). Each GPU, without overclock, have (aprox.) the same performance of a regular Titan, but the speed comunication beetween two GPU’s and dedicated memory are much much higher than 2x Titan’s cards, and that it’s the magic of Titan Z’s.
It’s important to say, for rendering in Blender with a Tz, to disable Multi-Gpu mode in order to full use the graphic’s card performance (since It’s a pseudo-SLI mode, which Blender don’t like very much).

Sorry for the long discussion here about cards.
About Blender version (2.73), you can ask us for new values and use them to compare with the previous version (2.72). Thanks

Thank you for posting wyslij but this benchmark is outdated.
I start a new thread for 2.73 in a few days.

Cheers, mib
