At 3:50 they have a benchmark for the new Apple M1 chip in the Macbook Air, and it is about 22% faster than my iMac desktop computer. That is with no active cooling. Apple is making mobile processors and getting desktop performance out of them.
There is a rumor that there will be an M2 chip for the future desktop iMac computers. Maybe eventually. The M1 was supposed to target mobile devices.
