Can AMD Radeon RX 7600 XT run HunyuanVideo?
13B parameter Video Gen model on 16GB GDDR6
VRAM Requirements
HunyuanVideo is a 13B parameter model. At full precision (FP16), it requires 40GB of VRAM. Your AMD Radeon RX 7600 XT has 16GB, so you'll need to quantize it to 4-bit (Q4) to fit.
Maximum quality, no quantization
Near-lossless, ~50% size reduction
Good quality, ~75% size reduction
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)
What This Means in Practice
At 4-bit precision, HunyuanVideo fits in AMD Radeon RX 7600 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.
