Can the RTX 3080 10 GB run ERNIE-Image (Turbo)?
Download Q6_K (6.8 GB). With the model's working memory it needs about 9.1 GB, leaving 0.9 GB spare on 10 GB. Quality: very close to the original. For better quality, Q8_0 (8.7 GB) also runs, with about 1.0 GB spilling into system RAM — a little slower, still practical.

Only for some workflows: ERNIE prompt enhancer (optional) (6.9 GB). 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
Ministral 3 3B: 7.7 GB as 16-bit (an optional prompt-enhancer LLM (6.9 GB) can be skipped). 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 16-bit 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 12 GB you could run ERNIE-Image at 8-bit or better (Q8_0, 8.7 GB) with no offloading: for example on the RTX 5070 12 GB, RTX 4070 Super 12 GB, RTX 4070 12 GB.

07Questions
How much VRAM does ERNIE-Image need?
Around 5.5 GB with the smallest file (Q2_K) and 11.0 GB with an 8-bit file (Q8_0), counting working memory and a small system reserve. The full 16-bit file needs about 18.4 GB.
Which ERNIE-Image file should I download for the RTX 3080 10 GB?
Q6_K (6.8 GB) from unsloth/ERNIE-Image-Turbo-GGUF. 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 ERNIE-Image 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.
