High Power Mode for M4 Pro Macs
Last year’s M3 Pro chip was a departure from the M1 Pro and M2 Pro. Compared to the M2 Pro, it came with more E-cores but fewer P-cores, as well as fewer GPU cores and less memory bandwidth.
As we wrote at the time, this meant that the architectural improvements to M3 mostly ended up being canceled out, making for a chip that was more efficient but often not meaningfully faster than its predecessor. Apple has added a High Power performance mode for the M4 Pro both in the Mac mini and in the new MacBook Pros. This feature was previously reserved for Max and Ultra chips and allows the chip to run at elevated speeds and temperatures for more extended periods of time; Apple says this should benefit GPU performance in particular at the expense of extra fan noise.
