Mixing a Nvidia 2080 with a 1080

in Technical Help (nuts n bolts)

I currently have two GIGABYTE GeForce GTX 1080 TI AORUS 11 GB GPUs in my system but I may have to replace one soon. If I do then the question is to replace with another 1080 or upgrade to a 2080? Does anyone KNOW if DAZ Studio 4.11 can work with such a mixed system efficiently?

    Yes, a lot of people use mixed systems (of those who have multiple GPUs in the first place). I have certainyl seen posts from people mixing a 20x0 and a 1080Ti.

    Thanks, that may be useful to know if I do need to replace a GPU. Perhaps you'd be kind enough to clear up another puzzle. I understand that in addition to CUDA cores the 2080 series also has Tensor cores. Are those also utilised in DAZ Studio rendering? If not, is it likely they will be soon?

    Tensor cores, as far as I know, are used in the AI Denoiser. RTX cores are the ones that would help with the actual rendering, but as yet Iray does not use them.

    Tensor cores are a machine learning thing so it would be likely the AI denoiser would utilize them. They've been around longer than the RTX cores so I would assume they're already in iray.

    Is the use of Tensor cores in Iray applications (such as DS) a matter for Nvidia to organise, or is this something that individual software companies (DAZ3d in this case) must do?

    It's an Iray thing, so dependent on nVidia.

    I will say the 4.11 beta denoiser even without tensor cores is pretty good, I have a 1080ti so I know I don't have tensor cores. I have it set to run after 250 iterations and if I'm not doing a character closeup that is often all I need for a perfectly acceptable image. If the tensor core enabled denoiser is better than that it will be a game changer for anyone with an RTX card.

    I'm not sure whether it's better or just faster - as we know, my GPU is practically pre-Cambrian.

    I've noticed a longer than usual delay between canvas draws at the 250 iteration mark but its not severe, on my GPU at least. Even if it took several minutes on older GPU's that would still be worth it IMO.
