Lowest measured peak memory per GPU for every Wan 2.2 model, from the model makers' own benchmark tables and READMEs. We have not run these ourselves.
| Model | Lowest measured peak / GPU | README says | Benchmarked GPUs |
|---|---|---|---|
| Wan2.2 T2V-A14B | 26.2 GB (T2V 480P, 8× H20) | README note on the single-GPU commands: "This command can run on a GPU with at least 80GB VRAM." (The benchmark single-GPU runs use model offloading.) | A100/A800, H100/H800, H20 |
| Wan2.2 I2V-A14B | 26.1 GB (I2V 480P, 8× H20) | — | A100/A800, H100/H800, H20 |
| Wan2.2 TI2V-5B | 22.6 GB (T2V 720P, 4× RTX 4090) | — | RTX 4090 |
