SLI and CUDA??

Evohc

Eh all,

This might sound really dumb, but I honestly don't fully understand the topic yet. For 3D apps in this industry that take advantage of Nvida CUDA technology, does SLI'ing two cards together add any benefits to the core count? I understand that Vram does not double, and each card uses it's own Vram for it's own work load. Does each card do the same for CUDA cores, or will the cores actually multiply/stack?

Thanks for any answers. I couldn't find much Googleing the topic.

Most professional applications do not take advantaged of SLI. But if you are using an application that does a lot of GPU compute and supports CUDA, it will probably be able to use 2 GPUs worth of CUDA core, no problem, but that depends on the application.

Blender's Cycles engine can use more than one graphics card to speed up rendering, but it doesn't use SLI to do it. It just has each card compute a separate bucket of the render and they both maintain a similar memory state to do it. Kind of like having a dual-core CPU.
