An accessible summary of the CPU cores in M1 chips, and how they appear to be managed by macOS to get the best for different classes of process.
Results from running 10-70 identical compute-intensive processes on M1 chips shows the differences in strategy between background and high priority settings.
macOS manages the loading and frequency of M1 cores according to the QoS set, and rules which differ between the original M1 and the M1 Pro.
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.
