I have a Dell XPS 15 9550. According to/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq, it has a maximum speed of 3.5 GHz, although that might be a boost speed. Running Ubuntu, it can certainly sustain 2.6 GHz. But running Fedora 32, it maxes out at 1.8 GHz (according to /proc/cpuinfo). I am currently on a Zoom call, and the sound is stuttering, and input lag is about two thirds of a second!
Why is this? Why does my CPU not go faster?
I see other questions referring to something called cpupower, but i don’t appear to have anything of that name installed.
