Can NVIDIA GeForce RTX 3060 12GB run HunyuanVideo?
13B parameter Video Gen model on 12GB GDDR6
Barely — requires CPU/RAM offloading
~1-3 tok/s (offload)
SpeedVery slow — expect 1-3 tokens/sec
QualityQuality is fine but the speed makes it impractical for interactive use
VRAM Requirements
HunyuanVideo is a 13B parameter model. At full precision (FP16), it requires 40GB of VRAM. Your NVIDIA GeForce RTX 3060 12GB only has 12GB — not enough even at maximum compression.
FP16 (Full Precision)40GB (need 28GB more)
Maximum quality, no quantization
Q8 (8-bit)22GB (need 10GB more)
Near-lossless, ~50% size reduction
Q4 (4-bit)14GB (need 2GB more)
Good quality, ~75% size reduction
