Of course the new Apple computers with M1 are much better than what they are replacing (except for the lower memory capacity and number of I/O ports).

However, that was an extremely low bar to pass, because Apple computers were notorious in recent years for their low performance compared to alternatives.


The comparisons with the older Apple products are useful for the Apple customers, to insure them that an upgrade is desirable, but they are completely useless for those who currently are not Apple customers.

For the latter, only the comparisons with Intel Tiger Lake, AMD Renoir and AMD Zen 3 are useful.

Compared to Intel Tiger Lake and AMD Zen 3, the differences in single-thread CPU performance are too small to have any practical consequence, so the right conclusion is that all these 3 processors have approximately the same single-thread performance, but the Apple M1 achieves it at a much lower power consumption and clock frequency.
