1. Dreamstudio is paid, with 2 EUR worth of credit for free.

2. The M1 GPU is an iGPU. A good iGPU, sure, but it's not anywhere near the performance of a dedicated, cooled GPU with dedicated VRAM.

On a 2060 Super with 8 GB of VRAM and with tensor cores it takes 15 seconds to infer with the default settings. If Dreamstudio uses deep learning GPUs then there is your answer to why it is as fast.
