ComfyUI x AMD

A PowerShell script that sets up ComfyUI with ROCm support for AMD RDNA GPUs on Windows. It uses uv for fast and reliable Python package management.

Features

• Native AMD GPU support (RDNA 3, 3.5, and 4)
• Fast installs using uv instead of pip
• One-command setup
• GPU configuration is saved between runs
• Handles venvs, dependencies, and ROCm PyTorch automatically

Supported GPUs

Generation	GPUs	Architecture
RDNA 3	RX 7900 XTX, RX 7900 XT, RX 7800 XT, RX 7700 XT, RX 7600	gfx1100
RDNA 3.5	Ryzen AI (Strix Point / Halo), Radeon 890M, 8060S	gfx1151
RDNA 4	RX 9070 XT, RX 9070	gfx1200

Prerequisites

• Windows 10 or 11 (64-bit)
• Git (download)
• PowerShell 5.1 or newer (already included with Windows)

Quick Install

Open PowerShell and run:

irm https://raw.githubusercontent.com/SystemVll/ComfyUI-AMD/main/ComfyUI-AMD.ps1 | iex

Manual Installation

1. Clone the repository:

   git clone https://github.com/SystemVll/ComfyUI-AMD.git
   cd ComfyUI-AMD

2. Run the script:

   .\ComfyUI-AMD.ps1

What the Script Does

• Installs uv if it isn’t already installed
• Clones the ComfyUI repository
• Creates a Python 3.12 virtual environment
• Installs the correct ROCm PyTorch build for your GPU
• Installs ComfyUI dependencies
• Configures HIP_VISIBLE_DEVICES
• Launches the ComfyUI web UI

Configuration

GPU Selection

On the first run, you’ll be asked which GPU generation you’re using:

• 1 – RDNA 3 (RX 7000 series)
• 2 – RDNA 3.5 (Ryzen AI)
• 3 – RDNA 4 (RX 9000 series)

Your choice is saved and reused on future runs.

Multi-GPU Systems

If more than one GPU is detected, you’ll be prompted to set HIP_VISIBLE_DEVICES:

• 0 – first GPU
• 1 – second GPU
• 0,1 – use both

Usage

First Run

.\setup.ps1

Follow the prompts and ComfyUI will start automatically.

Later Runs

.\setup.ps1

You can usually just press Enter — your settings are reused.

Open ComfyUI

Once running, open:

http://127.0.0.1:8188

Updating ComfyUI

cd ComfyUI
git pull
cd ..
.\setup.ps1

Any new dependencies will be handled automatically.

About uv

uv is a modern Python package manager written in Rust. Compared to pip, it’s significantly faster and tends to be more reliable, especially for large dependency trees.

Troubleshooting

uv not found

• Restart PowerShell and try again

Execution policy error

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

GPU not detected

• Update your AMD drivers
• Verify your GPU supports ROCm
• Try setting HIP_VISIBLE_DEVICES=0 manually

ComfyUI won’t start

• Make sure port 8188 isn’t already in use
• Check the console output for errors
• Delete the .venv folder and rerun the script

• uv: https://docs.astral.sh/uv/
• Models: https://huggingface.co/models

Notes

• First install can take a while, especially on slower connections
• ROCm PyTorch wheels are large (2–3 GB)
• Models are not included — place them in ComfyUI/models/
