What is the difference between cpufreq and power-profiles-daemon?

• cpufreq

  7 569 2.5 JavaScript

  System Monitor and Power Manager

I noticed that in ubuntu 21.04 there is a powermode setting that gives me 3 modes: high performance, balanced, and powersave. I saw that it seems to work (I looked at the task manager and looked at cpu%) and saw that there is a difference between the profiles. But It doesnt really give me a ton of control, nor can I check the frequency. I used to use cpufreq which gave me the cpu frequency and the ability to change governers/profiles. but I am not entirly sure if I should be using them together? It seems like when I have cpufreq the power mode (power-prodiles-daemon) doesnt feel like it does anything, and cpufreq shows no change in frequency?
