The RX 7800 XT is overwhelmingly underutilized while using UNET node (GGUF file) in any workflow regardless of quantized model and ComfyUI version used.

The lastest version of ComfyUI works flawlessly when using .safetensor models and the GPU power draw is good at 272 watts. But this is not the case with GGUF file. When using GGUF in a workflow, the GPU power draw does not go beyond 120 watts and the speed is 500s/iteration which is completely unusable. I tried Adranaline v26.1.1 and v25.20.01.17 as well but to no avail. Please help me fix this.

Following details might help:

ComfyUI version v0.11

Workflow includes :

Wan 2.1 Vace 14B GGUF Q5_0

Steps : 15

Length : 81

FPS : 15

Sampler : UniPC

This problem exists regardless of quantized models, workflow and ComfyUI version used.

I was happy to saw this, but after clean install on AMD rocm drivers, Comfyui Desktop and Portable, every Workflow crashs. Iam going back to rocm 6.4 on WSL :/
