How the two Efficiency cores in the M1 Pro and Max chips can match the performance of all four E cores in the original M1.

How can the two E cores in an M1 Pro/Max apparently match the performance of the four in the original M1? Answers, please.
Assigning ownership to an external bootable disk doesn’t always work in Recovery mode on an M1 Mac. But there’s an easy workaround.
Most users won’t have noticed, but Recovery now works quite differently on M1 series Macs than it did in Big Sur. Here’s a detailed explanation of the changes.
Does your M1 Mac run more slowly when it’s on battery power, or with Low Power mode enabled? An exploration of effects on its CPU cores provides an unexpected answer.
The E cores on the original M1 and M1 Pro chips appear to be managed quite differently, with respect to the performance of background processes at low QoS.
Apple’s first quad-core chip, the A10 launched 5 years ago, had 2 P and 2 E cores, but could only run one type of core at a time. We’ve come a long way since then.
Obtaining estimates for individual P and E core performance of processes run mainly in an ALU and those using floating-point and SIMD gives further insight and confirms the cores haven’t changed from M1 to M1 Pro.
How does macOS load processes onto the cores in M1 series processors? Are its policies similar between the original M1 and the M1 Pro?
