Can the RTX 5090 32 GB run Wan 2.2 Animate 14B?
Download FP8 (17.3 GB). With the model's working memory it needs about 22.6 GB, leaving 9.4 GB spare on 32 GB. Quality: practically identical to the original.

Alternatives: UMT5-XXL FP16 (11.4 GB). The 16-bit text encoder is a little more faithful; the smaller one is chosen here because it loads faster and needs less RAM. Sizes read from Hugging Face (2026-09-25). “Download” links start the file directly; the file name links are the same files the official ComfyUI workflows use.
System RAM: 32 GB or more. ComfyUI keeps the model file, the text encoder and the VAE in system RAM and moves them to the GPU as needed. With this set of files that is about 25.6 GB, plus roughly 6 GB for Windows, ComfyUI and a browser: 31.6 GB in total. With less RAM it still runs, but Windows starts swapping to disk and loading gets very slow. calculated

03The text encoder
UMT5-XXL + CLIP Vision H: 11.4 GB as 16-bit, 6.7 GB as FP8, 3.7 GB as GGUF Q4_K_M (plus CLIP Vision H (1.3 GB) for the input image). ComfyUI encodes the prompt first and can push the encoder out of VRAM before sampling, so it does not have to fit together with the model. On 32 GB the FP8 encoder fits on its own, so prompt encoding stays fast.
04About this GPU
The RTX 5090 32 GB is a Blackwell GPU with FP8 and FP4 hardware: ComfyUI computes Comfy-Org's FP8 files natively here, and NVFP4 files (where a model offers them) are faster still.

05What more VRAM would change
Nothing to gain for this model: the RTX 5090 32 GB already runs a top-quality file entirely in VRAM. More memory would only help with bigger images, longer clips or several models at once.

07Questions
How much VRAM does Wan 2.2 Animate need?
Around 11.8 GB with the smallest file (Q2_K) and 22.6 GB with an 8-bit file (FP8), counting working memory and a small system reserve. The full 16-bit file needs about 39.8 GB.
Which Wan 2.2 Animate file should I download for the RTX 5090 32 GB?
FP8 (17.3 GB) from Kijai/WanVideo_comfy_fp8_scaled.
Is FP8 faster than GGUF on the RTX 5090 32 GB?
It can be. This GPU has FP8 hardware, and ComfyUI computes FP8 natively for files made for it (Comfy-Org's fp8_scaled files), or for any FP8 file with the --fast fp8_matrix_mult option. GGUF files are unpacked on the fly, which costs some speed.
How much do I need to download for Wan 2.2 Animate on the RTX 5090 32 GB?
About 25.6 GB for the model file, text encoder and VAE listed on this page, and the same again free on disk. With a 32 GB card, 32 GB of system RAM or more is recommended.
