Best Graphics card for IRAY

The most important spec to look for is the CUDA core count, which is why the 780Ti beats the 980.

However, the 780Ti only comes in a 3GB variant, which may be limiting in terms of your scene size. For reference, I've easily hit 3GB in most of my scenes, which makes me thankful that I bought a card with 4GB (the 960 4GB card).

 

That's a myth with the memory full scene allocation inside the videocard, just export all your scene in OBJ and count the textures for size, bingo...it does not need even 1Gb for textures...duh!

even with 12Gb or memory video you STILL WILL NEED a lot of simple and normal DDR3 memory for preview rendering AND iray GPU rendering.

WHY?, dunno, but it does, and I have a GTX780Ti.

My workflow doesn't allow for me to export to objs, unfortunately :(

what workflow do you use?

Curious if anyone has done any benchmarks with iRay between the Titan and the 980 Series. I'm using a dual Titan in SLI Config, curious how the new 900 cards stack up. 

Thanks!

I find the numbering really weird. The 980Ti is basically a Titan X with 6GB (and slightly fewer cores). The 980, while very good, is not on the same level as these two other cards. Then you look at the GTX 690 and it compares with the GTX 970 for much cheaper. AMD's naming convention is even worse since they rebrand stuff all the time.

If you're using SLI for Studio, you're not getting the benefit of both cards. Nvidia specifically says to not use SLI for Iray. Also, which Titan and which GTX980? There are several Titan versions and 2 GTX980 versions.
