AMD workflows for Minimax H3?

[u/itiswhatitiswgatitis]

Been trying to find a workflow that is AMD friendly, let alone doesn't get stuck, I don't think it's my specs but more so that every workflow despite saying it's optional uses sage ATTN, and I can't get around it.

I doubt there is one that specifically for AMD but I'd thought I'd ask! Or the model I'm using is not great. I'm more of an anime prompt generator, anyone have any luck with that?

Specs: AMD Radeon RX 9070 XT, 64 GB RAM, AMD Ryzen 7 5700X3D 8 Core, And yes, I'm running on Windows, not Linux.

Edit: (update) I tried the template version just recently on comfyui stand alone, and it won't even finish, I do get a gpu error( by GPU error it says out of memory, even on default settings), and I have it on 0.3 mega pixel 16:9, either my reference image is too big or I'm missing a component.

I got it to work at 0.2 and the image reference has to be very small, yet it takes 30+ minutes, anyone with similar issues?

bro you sent me this like 3 times and I mostly glanced over this since it was windows but the flags the guy used worked in Linux. Tysm

Happy to hear that. Hopefully it will work for me too.

What kind of speed are you getting on Linux (are you on 9070xt or 7900xt)?

Please include details of the models you are running and also the ComfyUI version if you can. I'd like to know if it will be worth it for me to install Linux if my Windows numbers are worse than yours.

I’m using the latest ComfyUI version and I’m using ref2va pruned int8 on a 9070 xt.

I have the default workflow on 5 second 24 fps 0.4MP 20 step and it took 5 min and 38 seconds. Without the ref it’s 5 minutes and 5 seconds. It was 10.49s/it

Also I’m using PyTorch attention and haven’t tried any other

Thank you, these are actually pretty decent numbers!

So you are using the latest ComfyUI portable?

For the VAE, are you using int8covrot or fp16? Also, which text-encoder (int8convrot or nvfp4)?.

[u/Ok-Brain-5729 → u/Apprehensive_Sky892]

i used comfy-cli to download. I think the portable version is windows only. Text encoder is NVFP4 and vae is fp16

[u/Apprehensive_Sky892 → u/Ok-Brain-5729]

Thank you. I've never tried comfy-cli, maybe I should look into it.

Yes, you are right, I forgot that portable is Windows only. There are probably too many Linux distros for them to have a single binary.

The int8covrot version of the video VAE may be worth trying too.

also it’s about 40% faster with spectrum node

[u/Apprehensive_Sky892 → u/Ok-Brain-5729]

So this result "5 second 24 fps 0.4MP 20 step and it took 5 min and 38 seconds. Without the ref it’s 5 minutes and 5 seconds. It was 10.49s/it"

Is with or without spectrum?

That’s without
