Those ratios seem way off if you're referring to the M1 Max and not the base M1. If we use Geekbench CPU performance, the Ryzen 9 7945HX (which is from 2023) is around 12% faster single core and 32% faster multicore than the M1 Max (which is from 2021). If you look at the 2024 M4 Max, it's substantially faster than the Ryzen and Intel you mentioned.
