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.
performance
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.
If your Mac slows to a crawl, don’t just reboot it. Here’s how to discover what the likely cause is, and a structured approach to recovery.
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?
Not long ago, many of us paid for software which tied our Macs up for hours every month or so, defragmenting their hard disks. Why, and why not now?
Geekbench 5 scores for the M1 Pro are around 2800 single- and 12500 multi-core. Do they represent maximum performance, though?
Explore running test code of different types on the different cores in your M1 Mac. Provides insight into how your Mac performs, rather than just how fast it is.
A full Time Machine backup over SMB analysed in detail. This reveals that some of the measures reported in the log are likely to be inaccurate and misleading, and gives suggestions for improving performance.
Many processors like the ARM64 have instructions to perform fused multiply-add operations. Do they deliver reduced error and better performance?
