Can the RTX 4070 Super 12 GB run Wan Animate 2 (14B)?
Not at full quality. The 16-bit and 8-bit files are too big for the RTX 4070 Super 12 GB; the largest that fits is Q2_K (6.5 GB).
Q2_K (6.5 GB) fits with only 0.2 GB to spare (about 11.8 GB of 12 GB). Quality: heavy loss; a last resort. For better quality, Q3_K_M (8.6 GB) also runs, with about 1.9 GB spilling into system RAM - a little slower, still practical.
Also try the INT8 file (16.7 GB) on this GPU. It does not fit entirely, but a current ComfyUI streams the overflow from RAM and native 8-bit files often beat a small GGUF that does fit. Dynamic VRAM →

05About the RTX 4070 Super 12 GB
The RTX 4070 Super 12 GB is an Ada Lovelace GPU with hardware FP8, so ComfyUI can compute Comfy-Org's FP8 files natively: small and fast. (Plain FP8 files use FP8 maths with the --fast fp8_matrix_mult option.)
