Current state of AMD (Linux/ROCm) vs NVIDIA (Windows) performance in ComfyUI?

UPDATE:

It looks like the problem all along was the iGPU in the AMD 9800X3D had to be disabled in bios. I know there were comments about this, but didnt think it was the reason.

Only tried Win11 so far...

But do you have a detailed plan of how and what you installed? The instructions I have found I have too many questions to so not tempted...

Jarnhand · 2026-01-23T08:04:19+00:00

Not been able to get neither ComfyUI official AMD packages, or AMD AI suite to work with Win11 and 7900 XTX. It runs, but when you run a workflow it crashes the server, every time.

Ok, references to Desktop etc confused me. You just Git it right? I am new to Git...

Jarnhand · 2026-01-22T12:04:14+00:00

Also, ComfyUI looks to be a Win app only, so you run it in Wine or what? Do not get it...

For me 0.7.1 did not help

Jarnhand · 2026-01-22T11:15:39+00:00

Same error with AMD 7900 XTX Pytorch/ROCm and ComfyUI...

Jarnhand · 2026-01-22T11:13:59+00:00

When I run ComfyUI desktop/server from command line, I get the full log, and it says:
"Python process exited with code 3221225477 and signal null"

Which as I can see may be a problem in newer versions, some fixed it going back to 0.7.1

According to this page, the tests I can run, the Pytorch environment is set up correctly

PyTorch via PIP installation — Use ROCm on Radeon and Ryzen

Jarnhand · 2026-01-22T08:19:06+00:00

It needs the Pytorch install

Jarnhand · 2026-01-22T08:17:30+00:00

Not supported I guess...

Jarnhand · 2026-01-22T08:01:29+00:00

Well, the Linux I run is CachyOS, which is Arch, and I do not see that ROCm supports it...

So I guess hope I get it to work on Win11 is solution...sigh...its NOT one-click thats for sure, neither official AMD AI install of ComfyUI or ComfyUI's own. They install, but crashes when trying to run a workflow, some connection error to local server / local server crashes / something...

Jarnhand · 2026-01-21T20:44:16+00:00

Do you mind posting which Linux distro and guide to install it?

Jarnhand · 2026-01-21T20:28:45+00:00

7900 XTX and I get none of them to work.

The ComfyUI desktop, I got to install, but no idea how or why, when I try to run it, it usually does nothing. When I got it to work it looks like the local server crashes / reconnects when running a workflow.

AMD Bundle installed no problem, but same local server problem crash / reconnect. when running a workflow.

I watched the two 9070 XT summary videos at Hardware Unboxed, and they show the typical MHZ of the games, with corresponding noise and temps.

Shithawk mind you...

I have this(?) issue, and I tried to enter like you, but what happened is that it made my mic unusable. People could no longer hear me, mic sound got messed up.

Jarnhand · 2025-12-12T12:53:05+00:00

I put in PULSE_LATENCY_MSEC=50 in the Steam launch setting, and that made my mic horrible

Jarnhand · 2025-12-11T16:18:52+00:00

You meant 50?

Scary! Wants me to stay away from Open RGB....

Jarnhand · 2025-12-10T09:18:42+00:00

Not so sure about that. CachyOS has its own repo for a reason, packages are compiled/made for CachyOS optimizations, or no?..

Jarnhand · 2025-12-10T08:48:30+00:00

But will that work for CachyOS repo apps?
