Wan 2.1 Video variants on the NVIDIA GeForce GTX 1650
| Variant | Precision | Size | Total VRAM needed | Headroom | Fits? | |
|---|---|---|---|---|---|---|
| Q4_K_M GGUF | GGUF Q4_K_M | 8.5GB | 10.5GB | -6.5GB | ✗ OOM | Download ↗ |
| FP8 (Recommended)REC | FP8 | 13.1GB | 15.1GB | -11.1GB | ✗ OOM | Download ↗ |
| BF16 (Standard) | BF16 | 26.2GB | 28.2GB | -24.2GB | ✗ OOM | Download ↗ |
"Total VRAM needed" = variant size + 2.0GB estimated text-encoder/VAE overhead. Headroom = GPU VRAM (4GB) − total needed. Green ≥ 1.5GB headroom; Red ≤ −2GB (will OOM).
