GPUs/NVIDIA GeForce RTX 4070 SUPER/Wan Video 14B

Can NVIDIA GeForce RTX 4070 SUPER run Wan Video 14B?

14B parameter Video Gen model on 12GB GDDR6X

Yes — runs at 4-bit quantization

~0.2-0.4 clips/min

SpeedModerate speed, usable for interactive chat

QualityGood quality with slight degradation on complex reasoning

VRAM Requirements

Wan Video 14B is a 14B parameter model. At full precision (FP16), it requires 32GB of VRAM. Your NVIDIA GeForce RTX 4070 SUPER 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 GDDR6X at 504 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 NVIDIA GeForce RTX 4070 SUPER'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.
