Can the RTX 5080 16 GB run Qwen-Image-Edit (2511)?
Not at full quality. The 16-bit and 8-bit files are too big for the RTX 5080 16 GB; the largest that fits is Q3_K_M (9.9 GB).
Take Q3_K_M (9.9 GB). In use it comes to about 12.9 GB, with 3.1 GB left over on 16 GB. Quality: noticeable loss of detail. For better quality, Q4_K_M (13.2 GB) also runs, with about 0.2 GB spilling into system RAM - a little slower, still practical.
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 →
