Can AMD Radeon RX 7700 XT 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
HunyuanVideo works best with NVIDIA CUDA. Your AMD GPU may have limited or no support.
VRAM Requirements
HunyuanVideo is a 13B parameter model. At full precision (FP16), it requires 40GB of VRAM. Your AMD Radeon RX 7700 XT 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
