How many images per hour can Stable Diffusion generate?

SDXL on A100 (40GB): ~120-180 images/hr at 1024x1024 with 20 steps. On T4: ~40-60 images/hr. On RTX 3090: ~80-120 images/hr locally. Cost per image: ~$0.001-0.003 on cloud GPU.

Is self-hosted Stable Diffusion cheaper than DALL-E 3?

Yes — dramatically. DALL-E 3 at $0.04/image vs self-hosted SDXL at ~$0.001/image (40x cheaper on A100 rental). At >10K images/month, self-hosted pays for itself.

What GPU is best for Stable Diffusion?

RTX 4090 (24GB) is the best consumer GPU for SDXL. In cloud, A10G (24GB) offers the best cost-performance for SD. H100 is overkill for single-GPU SD inference.
