What hardware do you need to run Stable Diffusion locally?

Image models live in GPU memory (VRAM). The model you want decides the card: more VRAM means bigger models and larger images without errors.

Stable Diffusion 1.5~4-6 GBAlmost any NVIDIA card from the last 6 years; 16 GB Mac
SDXL~8 GB (12 GB comfortable)12-16 GB GPU; 24 GB Mac

Three good picks

Best value GPU

NVIDIA GeForce RTX 5060 Ti 16GB

16 GB VRAM · SDXL and Flux (fp8) without running out of memory

The cheapest current card with 16 GB of video memory. Make sure it is the 16 GB version, not the 8 GB one.

24 GB on a budget

NVIDIA GeForce RTX 3090 24GB

24 GB VRAM · Flux dev at full quality, larger batches

The classic local-AI card: 24 GB for less than a new 24 GB+ card. Mostly sold renewed or used, so check the seller and the return window. Needs a 750 W+ power supply.

No compromises

NVIDIA GeForce RTX 5090 32GB

32 GB VRAM · 32B models with long context, Flux at high quality

The most memory on a single consumer card. Expensive and power hungry (needs a 1000 W supply); only worth it if you run models every day.
