Can the RTX 3080 10 GB run Wan Animate 2 (14B)?
Nothing fits entirely, but Q2_K (6.5 GB) overflows by only about 1.8 GB. ComfyUI keeps that part in system RAM automatically: slower than a full fit, but usable.
Worth trying on this GPU: with an up-to-date ComfyUI, Dynamic VRAM (on by default for NVIDIA since March 2026) streams whatever does not fit from system RAM, and ComfyUI's own start-up message recommends native FP8/INT8 files over GGUF, saying they “will be faster even if they are larger than your memory”. So before settling for a heavily compressed GGUF, try the native INT8 file (16.7 GB). The file recommended above is the best one that fits entirely — the safe choice on older ComfyUI versions, AMD and Intel. Comfy blog: Dynamic VRAM →

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 14.8 GB, plus roughly 6 GB for Windows, ComfyUI and a browser: 20.8 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 10 GB the FP8 encoder fits on its own, so prompt encoding stays fast.
04About this GPU
The RTX 3080 10 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.

05What more VRAM would change
With 24 GB you could run Wan Animate 2 at 8-bit or better (Q8_0, 18.1 GB) with no offloading: for example on the RTX 4090 24 GB, RTX 3090 24 GB, RX 7900 XTX 24 GB.

07Questions
How much VRAM does Wan Animate 2 need?
Around 11.8 GB with the smallest file (Q2_K) and 22.0 GB with an 8-bit file (INT8), counting working memory and a small system reserve. The full 16-bit file needs about 38.1 GB.
Which Wan Animate 2 file should I download for the RTX 3080 10 GB?
Q2_K (6.5 GB) from realrebelai/Wan-Animate-2_GGUFs. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
Is FP8 faster than GGUF on the RTX 3080 10 GB?
No. This GPU has no FP8 compute, so ComfyUI converts FP8 weights back before the maths. FP8 only saves memory here; Q8_0 GGUF is the closer-to-original 8-bit pick.
How much do I need to download for Wan Animate 2 on the RTX 3080 10 GB?
About 14.8 GB for the model file, text encoder and VAE listed on this page, and the same again free on disk. With a 10 GB card, 32 GB of system RAM or more is recommended.
