This is probably the most unusual CPU comparison I've ever seen.
The Xeon processor that he's comparing against is a six thousand dollar processor from two years ago that is absolutely destroyed by modern processors that cost less than one eighth of the price.
It is expensive because it is designed for 8-processor systems, with 4.5TB memory support, and it runs cores that are glacially slow individually, but meant to make up for it by the massive amount of them (24).
Finally, the test is effectively a single-core test, since he's measuring the execution units.
I think Apple deserves some kudos for having delivered a chip that would be competitive on the open market (if it were available as such), but all of these ridiculous comparisons just don't paint a picture that has any dose of reality.
The M1 is one process node ahead of AMD and two process nodes ahead of Intel. With this advantage, the M1 is performance equivalent[1] to AMD Zen 2 processors (3XXX series, which is one architecture behind) but much more expensive. They are price equivalent[2] to AMD Zen 3 processors, but much slower total performance (though the M1 has about a 25% perf-per-watt lead against the 5600X when limited to the same power envelope). The integrated graphics, however, is a step above.
And before I get downvoted to hell, the easiest way to see the actual performance of the M1 as compared to other processors is to look at Apple-to-Apple comparisons (pun partially intended) by comparing benchmarks from an Apple M1 to an Apple Intel, and looking at that same processor off of the Apple platform compared against other processors.
If you look at Phoronix Apple M1 to Apple i7-8700B benchmarks (ignoring Rosetta benchmarks since those unfairly favor Intel), you'll see that they perform similarly (in some cases Intel pulls ahead, in some cases the M1 pulls ahead, and in some cases they tie). Then when you compare that 6-core processor to a modern AMD six core processor (5600X), the AMD processor is 33% faster in single-core and 80% faster in multi-core benchmarks.
1. Cut out the synthetic benchmarks, because they are provably biased (e.g. intel biased userbenchmark). Look for application benchmarks that depend on compute, like file compression, or software compiles, or even real-workload browser benchmarks)
2. At MSRP, before current issues with chip availability
