PLEASE watch in HD!!! Running the Octane Bennchmark with 2048 Cuda Cores. Two Nvidia GTX 590 cards with 4x512 CUDA cards. One 590 board has two GPUs with 512 CUDA Cores each, resulting in 2x2x512=2048 cores.

not bad but there's little VRAM in that rig...1.5 GB

This will always be the case. If you have a GTX 590 with 3 GB of VRAM it actually consists of two cards with only 1.5 GB of VRAM. It is one of the biggest limitations of the CUDA system. As far as I know it is a limitation to all GPU renderers. Does anyone konw how to avoid this? I dont know of a system that has more memory per actual GPU.

gtx 560 2gb
gtx 570 2.5gb
gtx 580 3gb
tesla 6gb

Does the tesla 6 GB have all the memory on 1 GPU or on multiple GPUs on 1 card. I really have no idea.

those are alle single gpu cards, means all vram attached to one chip...

Presumably that was in pathtracing mode?

...and if you like to still have 2048 cores for a reasonable price, you should take a look at this: http://www.refractivesoftware.com/forum ... 42&p=70182
