@stephenw10 said in Is there a command to view current cpu clock speed?:
How did it show those things enabled? The second output is after enabling it? In the BIOS?
powerd relies on some driver to actually control the cpu speed, est(4) for Intel CPUs. And that relies on either hard coded values or, far more commonly, values passed to it by ACPI. It's not unusual for those to be wrong or missing unfortunately.

No both outputs are taken right after one another it shows the proc jumping all around to different clock speeds as the processor sees fit.
My guess is the usage of hwpstate_intel is what allows the different visibility into the two different operating systems.
