I would agree with everything you said, but there is still the fact that M1 — while prioritising power consumption — is essentially reaching identical performance as the x86 chips. Sure, binned desktop Alder Lake is marginally faster (~20% , but it also pays a significant ~5x penalty in power consumption to get at most ~20% higher ST performance. So I am not sure about the accuracy of the statement that Apple prioritises power over performance — kind of seems to me that Apple gets both.
