Can AMD Radeon RX 7900 XT run CogVideoX-5B?
5B parameter Video Gen model on 20GB GDDR6
VRAM Requirements
CogVideoX-5B is a 5B parameter model. At full precision (FP16), it requires 18GB of VRAM. Your AMD Radeon RX 7900 XT has 20GB — enough to run it without any quantization.
Maximum quality, no quantization
Near-lossless, ~50% size reduction
Good quality, ~75% size reduction
Recommended system RAM: 40GB DDR5 (2x GPU VRAM minimum for model overflow)
What This Means in Practice
AMD Radeon RX 7900 XT can run CogVideoX-5B 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.
