After installing Intel Power Gadget, the tool is at /Applications/Intel Power Gadget/PowerLog. This lets you access all the data in the GUI, but doesn't require you to write your own code. 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. 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.
