GPUs/AMD Radeon RX 7900 XT/Stable Video Diffusion

Can AMD Radeon RX 7900 XT run Stable Video Diffusion?

1.5B parameter Video Gen model on 20GB GDDR6

Yes — runs at full precision
~0.4-0.5 clips/min
SpeedFastest possible inference
QualityMaximum quality, no degradation
Stable Video Diffusion works best with NVIDIA CUDA. Your AMD GPU may have limited or no support.

VRAM Requirements

Stable Video Diffusion is a 1.5B parameter model. At full precision (FP16), it requires 8GB of VRAM. Your AMD Radeon RX 7900 XT has 20GB — enough to run it without any quantization.

Q8 (8-bit)5GB (15GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)3.5GB (17GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 20GB GDDR6 at 800 GB/s bandwidth
Recommended system RAM: 40GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

AMD Radeon RX 7900 XT can run Stable Video Diffusion at full precision for video generation. You can generate short video clips from text prompts or images at maximum quality. Video generation is very compute-intensive — expect each clip to take 30 seconds to several minutes depending on resolution and length.
