Can I run Qwen-Image on Nvidia GeForce RTX 4070 (12GB)?
Needs ~14 GB at Q4_K_M GGUF, but only ~11 GB is usable on Nvidia GeForce RTX 4070 (12GB). With aggressive CPU offload it can run on as little as ~3 GB, much slower.
Needs ~14 GB at Q4_K_M GGUF, but only ~11 GB is usable on Nvidia GeForce RTX 4070 (12GB). With aggressive CPU offload it can run on as little as ~3 GB, much slower.
The gap is about 3 GB: Qwen-Image needs roughly 14 GB and Nvidia GeForce RTX 4070 (12GB) leaves only about 11 GB usable for a model. The lightest tracked hardware that runs Qwen-Image is the Nvidia GeForce RTX 4060 Ti (16GB) at 16 GB. See Qwen-Image on Nvidia GeForce RTX 4060 Ti (16GB).

FAQ
Can Nvidia GeForce RTX 4070 (12GB) run Qwen-Image?
Needs ~14 GB at Q4_K_M GGUF, but only ~11 GB is usable on Nvidia GeForce RTX 4070 (12GB). With aggressive CPU offload it can run on as little as ~3 GB, much slower.
How much VRAM does Qwen-Image need?
Nvidia GeForce RTX 4070 (12GB) does not have enough memory. At Q4_K_M GGUF the realistic peak is ~14 GB of VRAM, versus ~57 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~3 GB, much slower.
What do I use to run Qwen-Image locally?
Qwen-Image runs in ComfyUI or Nunchaku (SVDQuant 4-bit). It loads as a diffusion checkpoint plus its text encoder and VAE, not a single chat command.
