Given what we know about the base M5, is it really a significant improvement on the base M4. What features should we be looking at?
efficiency
How operating frequencies of CPU cores used by the latest base M5 chip compare with those from previous families in the M series, and what that means. Complete with updated tables for all current chips.
A call for help: can you help complete this table of all the CPU core frequencies of M-series chips? M3 Ultra and M5 values are requested, please.
How your Mac can use less energy and power, run its battery down less, generate less heat, and keep its P cores for the work you want it to do for you.
How much faster are the P cores in M3 and M4 chips, compared to late Intel Macs? How do they compare when running threads at low QoS, such as those of macOS background tasks?
How to more than double the speed of a thread run on the E cores, by running another 11 threads at the same time.
Provides maximum frequencies for E and P cores in each of the M-series, a table of all frequency steps used by current M-series chips, and explanation of how they have come about and their importance.
In any M-series family, I’ve always assumed that P and E cores were the same, whether it’s a base or Ultra variant. That isn’t correct, though.
How CPU P cores have a frequency limit applied in Low Power mode, and how macOS regulates power use or temperature by controlling core frequency.
Power use in two in-core performance tests, by number of threads run, leading to estimates of total energy used by P and E cores running the same code, at high frequencies. How efficient are the CPU cores in the M4?
