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 silicon
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?
Passing your Mac on to a new owner has got much easier and more reliable in Monterey – so long as it has got a T2 or M1 series chip.
Geekbench 5 scores for the M1 Pro are around 2800 single- and 12500 multi-core. Do they represent maximum performance, though?
Want to create a bootable external disk for your M1 Mac? Here’s how to do it in full detail, from erasing the volumes through to how to remove it safely.
M1 Macs are different, as they always start booting from their internal SSD. Basic configurations are simple, reliable with well-established disaster recovery methods.
For thirty years, I’ve been cautioning people to avoid buying notebook Macs, and to prefer desktop systems. That’s changed.
From the IBM PC XT with its 10 MB hard disk to a SoC which moves data to its SSD at over 7 GB/s. How CPUs interface with peripherals.
