What are you comparing, CPU performance?
EDIT: I tried to find some numbers on the NPU Performance in ML Models, which is difficult, but shows quite differences to running models on Raspberry Pi CPUs, e.g. https://www.reddit.com/r/OrangePI/comments/1annxuk/comment/kyp9nfo/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button - yeah that is random people writing stuff. I can’t judge.
