Can the RTX 4060 Laptop 8 GB run Wan 2.2 T2V A14B?
Not entirely. Even Q2_K is 1.6 GB over 8 GB, so ComfyUI keeps part of it in system RAM.
Nothing fits entirely, but Q2_K (5.3 GB) overflows by only about 1.6 GB. ComfyUI keeps that part in system RAM automatically: slower than a full fit, but usable.
Also try the FP8 file (14.3 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 →
Using Kijai's WanVideoWrapper instead of the native nodes? Its WanVideo BlockSwap node keeps part of the model in system RAM. To run the FP8 file (14.3 GB) on RTX 4060 Laptop 8 GB, start with blocks_to_swap ≈ 31 (of 40). Each block is about 0.4 GB; raise the number if you still run out of memory, lower it for speed. estimate WanVideoWrapper →
01With more VRAM
With 20 GB you could run Wan 2.2 T2V at 8-bit or better (FP8, 14.3 GB) with no offloading.

“Needed” adds 3.5 GB of working memory for Wan 2.2 T2V and a 0.8 GB reserve. Sizes 2026-10-01. Wan 2.2 A14B uses two files of this size (high-noise and low-noise); only one sits in VRAM at a time, both must fit in system RAM.

05About the RTX 4060 Laptop 8 GB
The RTX 4060 Laptop 8 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.) As a laptop GPU it runs at a lower power limit than desktop cards (35–115 W depending on the laptop). The memory verdicts are the same; speed depends heavily on how much power the laptop maker allows.

06Questions
How much VRAM does Wan 2.2 T2V need?
Around 9.6 GB with the smallest file (Q2_K) and 18.6 GB with an 8-bit file (FP8). The full 16-bit file needs about 32.9 GB.
Which Wan 2.2 T2V file should I download for the RTX 4060 Laptop 8 GB?
Q2_K (5.3 GB) from QuantStack/Wan2.2-T2V-A14B-GGUF. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
FP8 or Q8_0 for Wan 2.2 T2V on the RTX 4060 Laptop 8 GB?
FP8 (14.3 GB): the RTX 4060 Laptop 8 GB computes it natively, while Q8_0 (15.4 GB) is unpacked on the fly.
How much do I need to download for Wan 2.2 T2V on the RTX 4060 Laptop 8 GB?
17.6 GB: Wan2.2-T2V-A14B-HighNoise-Q2_K.gguf, Wan2.2-T2V-A14B-LowNoise-Q2_K.gguf, umt5_xxl_fp8_e4m3fn_scaled.safetensors, wan_2.1_vae.safetensors.
