I was looking into this. The M5 performance cores can be scaled down to match efficiency cores in performance and power usage.
I believe they lower the clock speed, limit how much work is done in parallel on each core, and limit how aggressive the speculative execution is so less work is wasted.
Source for this?
Not sure if this was available in previous gens but my M4 Pro can run in low power mode. It's amazing. I can work for hours and only use 10-15% of the battery.
