Is there some data to confirm that? Both AMD and Intel just came out with their new 5Ghz+ CPUs. I doubt that even M2 is faster.

Not generally true. On geekbench, both Intel and AMD have offerings that outscore both M1 and M2 on single core.

It did when it came out. But it got already leapfrogged. Calculating fibonacci(45) with a recursive javascript function takes 13s on my m1pro and 7s on my ryzen 7600x. Profiling our angular app in chrome the initial render takes 200ms on m1pro and 130ms on my ryzen 7600x.

Apple silicon is still the master of performance per watt. But raw performance: It really was just tsmc 5nm what gave apple the edge. Apple will shine again when they sit exclusivly on tsmc 3nm, but until then, not so much.
