QualityMaximum quality, no degradation

VRAM Requirements

Stable Diffusion XL is a 6.6B parameter model. At full precision (FP16), it requires 16GB of VRAM. Your NVIDIA RTX 6000 Ada has 48GB — enough to run it without any quantization.

FP16 (Full Precision)16GB (32GB free)

Maximum quality, no quantization

Q8 (8-bit)8GB (40GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)6GB (42GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 48GB GDDR6 ECC at 960 GB/s bandwidth
Recommended system RAM: 96GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

NVIDIA RTX 6000 Ada runs Stable Diffusion XL at full precision with room to spare. You can generate high-resolution images, use complex prompts, and batch multiple generations. Expect fast generation times at 1024x1024 and above.

How to Set It Up

Step 1: Install ComfyUI

git clone https://github.com/comfyanonymous/ComfyUI.git && cd ComfyUI && pip install -r requirements.txt

ComfyUI is the recommended UI for Stable Diffusion and FLUX models.

Step 2: Download the model

Download Stable Diffusion XL weights from HuggingFace and place them in ComfyUI/models/. The model is approximately 16GB at full precision.

Step 3: Launch and generate

python main.py

Open http://localhost:8188 in your browser. You can use the full precision weights.
