[P] GPU Benchmark: Stable Diffusion v1.5 on 23 consumer GPUs (generating 460,000 fancy QR codes)

We benchmarked SD v1.5 on 23 consumer GPUs - To generate 460,000 fancy QR codes.

The best performing GPU/backend combination delivered almost 20,000 images generated per dollar (512x512 resolution).

Some key observations:

1. Do not use the GTX series GPUs for production stable diffusion inference. Absolute performance and cost performance are dismal in the GTX series, and in many cases the benchmark could not be fully completed, with jobs repeatedly running out …
