Can the RTX 3080 10 GB run Qwen-Image-Edit (2511)?
Not entirely. Even Q2_K is 0.5 GB over 10 GB, so ComfyUI keeps part of it in system RAM.
Nothing fits entirely, but Q2_K (7.5 GB) overflows by only about 0.5 GB. ComfyUI keeps that part in system RAM automatically: slower than a full fit, but usable.
Also try the FP8 file (20.5 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 →
01With more VRAM
With 24 GB you could run Qwen-Image-Edit at 8-bit or better (FP8, 20.5 GB) with no offloading: for example on the RTX 4090 24 GB, RTX 3090 24 GB, RX 7900 XTX 24 GB.

04The text encoder
At 9.4 GB even the smallest Qwen2.5-VL 7B file is too big for 10 GB, so it runs from system RAM. That slows down reading the prompt, not the picture. Sizes: 16-bit 16.6 GB, FP8 9.4 GB. Why the encoder does not count against VRAM →

06About the RTX 3080 10 GB
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.

07Questions
How much VRAM does Qwen-Image-Edit need?
Around 10.5 GB with the smallest file (Q2_K) and 23.5 GB with an 8-bit file (FP8). The full 16-bit file needs about 43.9 GB.
Which Qwen-Image-Edit file should I download for the RTX 3080 10 GB?
Q2_K (7.5 GB) from unsloth/Qwen-Image-Edit-2511-GGUF. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
FP8 or Q8_0 for Qwen-Image-Edit on the RTX 3080 10 GB?
Q8_0 (21.8 GB). The RTX 3080 10 GB has no FP8 maths, so FP8 (20.5 GB) only saves memory and is a step further from the original.
How much do I need to download for Qwen-Image-Edit on the RTX 3080 10 GB?
17.1 GB: qwen-image-edit-2511-Q2_K.gguf, qwen_2.5_vl_7b_fp8_scaled.safetensors, qwen_image_vae.safetensors.
