Can AMD Radeon RX 7600 run FLUX.1 Dev?
12B parameter Image Gen model on 8GB GDDR6
Barely — requires CPU/RAM offloading
~1-3 tok/s (offload)
SpeedVery slow — expect 1-3 tokens/sec
QualityQuality is fine but the speed makes it impractical for interactive use
FLUX.1 Dev works best with NVIDIA CUDA. Your AMD GPU may have limited or no support.
VRAM Requirements
FLUX.1 Dev is a 12B parameter model. At full precision (FP16), it requires 32GB of VRAM. Your AMD Radeon RX 7600 only has 8GB — not enough even at maximum compression.
FP16 (Full Precision)32GB (need 24GB more)
Maximum quality, no quantization
Q8 (8-bit)16GB (need 8GB more)
Near-lossless, ~50% size reduction
Q4 (4-bit)10GB (need 2GB more)
Good quality, ~75% size reduction
Your GPU VRAM: 8GB GDDR6 at 288 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

How to Set It Up
Step 1: Install ComfyUI
git clone https://github.com/comfyanonymous/ComfyUI.git && cd ComfyUI && pip install -r requirements.txtComfyUI is the recommended UI for Stable Diffusion and FLUX models.
Step 2: Download the model
Download FLUX.1 Dev weights from HuggingFace and place them in ComfyUI/models/. The model is approximately 32GB at full precision.
Step 3: Launch and generate
python main.pyOpen http://localhost:8188 in your browser. You can use the full precision weights.
