Apple M1 mac GPU is orders of magnitude slower than a single Nvidia T4 GPU with CUDA for certain machine learning tasks. This was my experience while trying to run Stable diffusion Inpainting/Outpainting to expand images. This task took a mere 5-10 seconds on Nvidia T4, while it took almost 5-6 mins on M1 mac. Nvidia T4 was almost 30x or more faster. I’m not sure how much of this performance is attributable only to the GPU and how much to CUDA working only on Nvidia T4.
