Benchmarks are of course just benchmarks, but the single-core performance is better for the M2, and the range-topping M2 is about 2x faster than the i9.
Also, regardless of how something compares, if it is ever memory-bandwidth bound, then faster RAM should help. While most tasks may be CPU or IO bound, AFAIK there can still easily be memory bound tasks in real-world workloads.
I picked the i9-11900k for comparison since I think that was the last one to only support DDR4 (making it “DDR4 era”). Ryzen maybe faster in the DDR4 era though?

I wouldn’t really trust this site. Videos that go through a lot of different benchmarks /programs and games are way better. This shows the M2 being pretty average/normal between other laptop CPUs: youtu.be/FWfJq0Y4Oos
And this shows M2 Ultra vs the top Intel CPU at that time: youtu.be/buLyy7x2dcQ
The things that’s impressive about the M[x] chips are their efficiency. Apple basically lying with the performance graphs they put out is really frustrating when they have an actual amazing metric they could show: power consumption. That’s what a RISC architecture is good at
