Intel Power Gadget has a rather obscure PowerLog command line utility.

You can of course log the spontaneous changes to the thermal throttling of CPU with pmset -g thermlog and then map that to the CPU specifications if you can gather them elsewhere. The boosts when a single core can run over clocked are less likely to be easily measured, but you can measure thermal throttling very simply with the thermal logging of pmset. With 8 cores on many MacBook Pro and dozens of cores on the iMac Pro - you're boiling a ton of complexity down to one number. Since the code and each core of a CPU can and will change hundreds of times a second based on ephemeral load factors, power optimizations that consider what's visible on the screen, what network data arrives, the idea that a modern CPU even has one 'common' clock rate at any one point in time seems to vastly over-simplify reality. CPU interrupts on macOS are shaped in intervals of 150 ms and much of this detail is public from WWDC 2013 and later on power management, App Nap ( Session 209 in particular is both good and approachable) and battery life optimizations on macOS. Also, please share your love by sharing this article with your friends.I have to think this is a bit of an X Y question in that 'What are you going to do once you get this number?' and want to answer that directly, but let's dive a bit into what you're trying to measure. In case if you have any query regards this article you may ask us. I hope you like the guide How to check the CPU usage on computer. How to check CPU usage on a Windows PC # Using Task Manager # Using the Resource Monitor app # How to check CPU usage on a Mac # Using the Activity Monitor app # Final note # Launch Activity Monitor to view your computer’s disk activity and usage, check network traffic, check system memory and see real-time statistics on CPU usage. Mac OS X comes with a utility that you can use to monitor which applications and processes demand the most from your MacBook Pro’s CPU. If you trust the MacBook Pro as your commercial desktop replacement or mobile Computing fellow, you might want to monitor your system’s CPU usage to diagnose system slowdowns or see which apps work best.
