Can I run Stable Diffusion 3.5 Large on Nvidia GeForce RTX 2060 (6GB)?

Compatibility verdict VRAM check

No, not enough memory would not load

Needs ~7 GB at Q4 GGUF, but only ~5 GB is usable on Nvidia GeForce RTX 2060 (6GB). With aggressive CPU offload it can run on as little as ~5 GB, much slower.

Needs ~7 GB Device usable ~5 GB

Needs ~7 GB at Q4 GGUF, but only ~5 GB is usable on Nvidia GeForce RTX 2060 (6GB). With aggressive CPU offload it can run on as little as ~5 GB, much slower.

The gap is about 2 GB: Stable Diffusion 3.5 Large needs roughly 7 GB and Nvidia GeForce RTX 2060 (6GB) leaves only about 5 GB usable for a model. The lightest tracked hardware that runs Stable Diffusion 3.5 Large is the Nvidia GeForce RTX 3060 Ti (8GB) at 8 GB. See Stable Diffusion 3.5 Large on Nvidia GeForce RTX 3060 Ti (8GB).

FAQ

Can Nvidia GeForce RTX 2060 (6GB) run Stable Diffusion 3.5 Large?

Needs ~7 GB at Q4 GGUF, but only ~5 GB is usable on Nvidia GeForce RTX 2060 (6GB). With aggressive CPU offload it can run on as little as ~5 GB, much slower.

How much VRAM does Stable Diffusion 3.5 Large need?

Nvidia GeForce RTX 2060 (6GB) does not have enough memory. At Q4 GGUF the realistic peak is ~7 GB of VRAM, versus ~19 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~5 GB, much slower.

What do I use to run Stable Diffusion 3.5 Large locally?

Stable Diffusion 3.5 Large runs in ComfyUI or Draw Things (among others). It loads as a diffusion checkpoint plus its text encoder and VAE, not a single chat command.
