I'm curious why they decided to go this route, but glad to see it. Perhaps ~4 efficiency cores is simply just enough for the average MBP user's standard compute?

In January, after researching, I bought an apple restored MBP with an M2 Max over an M3 Pro/Max machine because of the performance/efficiency core ratio. I do a lot of music production in DAWs, and many, even Apple's Logic Pro don't really make use of efficiency cores. I'm curious about what restraints have led to this.. but perhaps this also factors into Apple's choice to increase the ratio of performance/efficiency cores.

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.
