I will measure the quality and time of image generation at each sampling step with Stable Diffusion.This time, I tried generating images of supercars.I&#39;m using an H100 GPU. The image size is 512x512. 1 step / Time taken: 0.8 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s1.png"/> 2 steps / Time taken: 1.4 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s2.png"/> 5 steps / Time taken: 3.1 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s5.png"/> 10 steps / Time taken: 6.0 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s10.png"/> 20 steps / Time taken: 11.9 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s20.png"/> 50 steps / Time taken: 29.7 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s50.png"/> 100 steps / Time taken: 58.6 sec.<img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/s100.png"/> <img src="https://assets.blueqat.com/public/uploads/us-east-2:4805ff4b-c3cc-4344-b165-86544c34d0bf/2024/03/18/plot_sd.png"/> The computation time seems to scale linearly with the number of sampling steps.Although images with 100 steps appear to be more detailed, there didn&#39;t seem to be much difference starting from about 20 steps. This has made me want to try generating various images with a higher number of sampling steps.
