I ordered an NVIDIA Tesla K80 off eBay (and the power adapter... and the blower fan shroud, etc.) and intend to install it when it arrives around Thursday or Friday. I'm hoping that after I install the NVIDIA Linux datacenter drivers I'll be able to use the card with SD. My only worry is that because the K80 is two GPUs on one board, that it might only utilize one of them, with only 12 GB of VRAM instead of both chips and all 24 GB. 5992 CUDA cores and 24 GB VRAM would be a pretty decent SD accelerator for only $150.

I really want to put one of these in my Dell Precision workstation, and I share similar concerns. I have an older Quadro in it now and could use a proper upgrade, but I really want to wait for the 4000 series cards due in a few months. Craft Computing on Youtube has the best information from what I have seen so far. I don't like watching Youtube videos for information like this, but I understand why creators have moved to this medium in general. Linux should be much easier to configure for using the K80 to capacity.

You'll be able to render but it won't be fast, those CUDA cores are ancient and VRAM speed is slow. Check the Stable Diffusion discord for more info, but I found these comments: > one minute per 512x512 @ 50 steps > 1m20s to run 50 ddims on 512x512 vs 2080 ti in 12 seconds You'll have to run the optimized model as well, since you can't connect the 2x 12GB together.

    The architecture of the k80 just doesn't allow memory sharing or pooling. The newer systems (Pascal and above I think?) can allow it on the right hardware but it's all datacenter and workstation cards for that.

      Man, feel like I shoulda picked up the M40 instead then, since it was 24 GB VRAM in total. :( Oh well, I've spent $90 on dinners and had far less fun than I will have with this video card when it arrives, so I can't say it was wasted money... and I can always just buy an M40 off eBay. If RTX 3090 prices keep dropping through the floor, I may just bite the bullet and pick one up. I saw a ZOTAC on sale for $999 recently, which is $500 less than the launch MSRP of $1499 (which honestly is where it should have launched anyway... so far as I'm concerned, these cards only just now hit reasonable pricing).
