Can you be more specific as to what workloads you arecomparing? I find methodical comparisons quite scant. Anandtech has one page that includes the Ryzen 7 4800U and Ryzen 9 4900HS[0] for some synthetic integer/floating point benchmarks. In many cases the Apple Silicon M1 outperforms the Ryzen 7 4800U and in several it outperforms the Ryzen 9 4900HS. It's a bit difficult to extract from that how well they compete across all workloads, but it looks like they are quite comparable.

(And this is from someone who spends a lot of time trying to correct the misconception that the M1 outperforms all competitive processors.)
