Can AMD Radeon RX 7900 GRE run Mochi 1?

10B parameter Video Gen model on 16GB GDDR6

Yes — runs at 8-bit quantization
~0.1-0.2 clips/min
SpeedFast inference, near-native speed
QualityNear-lossless — virtually identical to FP16
Mochi 1 works best with NVIDIA CUDA. Your AMD GPU may have limited or no support.

VRAM Requirements

Mochi 1 is a 10B parameter model. At full precision (FP16), it requires 30GB of VRAM. Your AMD Radeon RX 7900 GRE has 16GB, so you'll need to quantize it to 8-bit (Q8) to fit.

FP16 (Full Precision)30GB (need 14GB more)

Maximum quality, no quantization

Q8 (8-bit)16GB (0GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)10GB (6GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 16GB GDDR6 at 576 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

Mochi 1 at 8-bit precision on AMD Radeon RX 7900 GRE generates video clips with near-identical quality to full precision. Generation times are similar — video gen is bottlenecked by compute more than memory at this precision. A solid setup for local video generation.
