Can NVIDIA GeForce RTX 4070 Ti SUPER run HunyuanVideo?

13B parameter Video Gen model on 16GB GDDR6X

Yes — runs at 4-bit quantization
~0.3-0.4 clips/min
SpeedModerate speed, usable for interactive chat
QualityGood quality with slight degradation on complex reasoning

VRAM Requirements

HunyuanVideo is a 13B parameter model. At full precision (FP16), it requires 40GB of VRAM. Your NVIDIA GeForce RTX 4070 Ti SUPER has 16GB, so you'll need to quantize it to 4-bit (Q4) to fit.

FP16 (Full Precision)40GB (need 24GB more)

Maximum quality, no quantization

Q8 (8-bit)22GB (need 6GB more)

Near-lossless, ~50% size reduction

Q4 (4-bit)14GB (2GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 16GB GDDR6X at 672 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

At 4-bit precision, HunyuanVideo fits in NVIDIA GeForce RTX 4070 Ti 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.
