GPUs/AMD Radeon RX 7700 XT/Wan Video 14B

Can AMD Radeon RX 7700 XT run Wan Video 14B?

14B parameter Video Gen model on 12GB GDDR6

Yes — runs at 4-bit quantization
~0.1-0.2 clips/min
SpeedModerate speed, usable for interactive chat
QualityGood quality with slight degradation on complex reasoning
Wan Video 14B works best with NVIDIA CUDA. Your AMD GPU may have limited or no support.

VRAM Requirements

Wan Video 14B is a 14B parameter model. At full precision (FP16), it requires 32GB of VRAM. Your AMD Radeon RX 7700 XT has 12GB, so you'll need to quantize it to 4-bit (Q4) to fit.

FP16 (Full Precision)32GB (need 20GB more)

Maximum quality, no quantization

Q8 (8-bit)18GB (need 6GB more)

Near-lossless, ~50% size reduction

Q4 (4-bit)11GB (1GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 12GB GDDR6 at 432 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

At 4-bit precision, Wan Video 14B fits in AMD Radeon RX 7700 XT's VRAM but video quality may show artifacts, especially in motion consistency and fine details. Generation times will be longer. Usable for experimentation, but a GPU with more VRAM will produce noticeably better results.
