Can the RTX 3060 12 GB run Wan 2.2 TI2V 5B?
Yes, but only just: Q8_0 leaves 2.8 GB free on the RTX 3060 12 GB.
Take Q8_0 (5.4 GB). In use it comes to about 9.2 GB, with 2.8 GB left over on 12 GB.
Using Kijai's WanVideoWrapper instead of the native nodes? Its WanVideo BlockSwap node keeps part of the model in system RAM. To run the 16-bit file (10.0 GB) on RTX 3060 12 GB, start with blocks_to_swap ≈ 7 (of 30). Each block is about 0.3 GB; raise the number if you still run out of memory, lower it for speed. estimate WanVideoWrapper →

04About the RTX 3060 12 GB
The RTX 3060 12 GB (Ampere) has no FP8 compute. FP8 files still load and save memory, but ComfyUI converts them back before the maths, so there is no speed gain - Q8_0 GGUF is the closer-to-original 8-bit choice. ComfyUI can compute INT8 files natively on NVIDIA, which is worth a try where a model offers one.
