> Perhaps ~4 efficiency cores is simply just enough for the average MBP user's standard compute?

I believe that’s the case. Most times, the performance cores on my M3 Pro laptop remain idle.

What I don’t understand is why battery life isn’t more like that of the MacBook Airs when not using the full power of the SOC. Maybe that’s the downside of having a better display.

Curious how you're measuring this. Can you see it in Activity Monitor?

Yes I think so. Display is a huge fraction of power consumption in typical light (browsing/word processing/email) desktop workloads.

I use an open source app called Stats [1]. It provides a really good overview of the system on the menu bar, and it comes with many customization options.

Cool, thanks for the tip!

Yes, processor history in the activity monitor marks out specific cores as Performance and Efficiency.

Wow, I didn't even realize you could double-click the CPU graph on the main screen to open that view.
