On Linux it is very easy to measure everything you want to know with turbostat.

This program should be available as a package in whatever distribution you use, but it is preferable to use the most recent version, which you can make and install yourself from the Linux kernel sources, typically located at:

/usr/src/linux/tools/power/x86/turbostat/


Turbostat can show the clock frequencies of each core and all the other relevant information.


You should run simultaneously with turbostat some program which completely loads the processor on the desired number of cores, e.g. firestarter or some AVX-512 / AVX2 benchmark.
