5850U is an 8 core CPU with a TDP that is adjustable between 10-25w. If you want to keep it to 4 cores just so it is a fair fight, there's the 5400U/5450U. AMD does pretty well...

Yeah I'd say the M1 and latest AMD CPUs are virtually tied for fastest single threaded performance, edging out the best by Intel.

But for something like compilation which is multithreaded obviously the higher core count will win.
