SD3 with ComfyUI on WINDOWS with AMD RDNA3 HIP/ROCm and ZLUDA

Download and run Stable Diffusion 3 from the Hugging Face Repository on a Windows 10 or 11 machine with AMD Hardware using ComfyUI. In my case, I am using a 7900XT, but this should work with most RDNA2 or RDNA3 AMD GPUs. This should also work for any Stable Diffusion 1.5 or SDXL workflow.

Thanks for this video, mate. I oddly appreciate when there’s a lack of cuts/editing, so you can see a lot of details that might help to figure out some issues. I really regret buying my 7900 XTX every day while trying to play with AI...

Something not covered in this video, but it is on the ReadMe of ComfyUI ZLuda is that you need to make sure that you edit your System Variable settings in Windows. The variable HIP_Path was there already for me, but I needed to add the one to the Path system Variable. Specifics are in the ReadMe. Otherwise this worked great with Flux. Thank you so much!

Super confusing, jumping through many menues. Will somebody in the world finally create a step-by-step tutorial on how to make SD3 run properly on AMD cards?

Thanks. I saw sd3 was released yesterday and i was wondering about AMD compatibility

So when I click Queue Prompt, it says Loading 1 new model and then I get a rocBLAS error: Cannot read... and then a path to TensileLibrary.dat: No such file or directory for GPU arch : gfx1036. I'm running a 7900XT like you.

I can run it but I do not managed to get a batch with 6800 and a lot of other problems, And the model is very censored, and really worse than others

Honestly you should redo this video. Provide exact commands to paste in CMD in the description and tell exactly which models to download. You can mention the text encode as an aside but you should definitely not leave it in a wishy washy "well... download which one you want" without recommending one definitively.

With all due respect for the work you put in, skip the parts where everything doesn't work and re edit...
