Has anyone else seen behavior like this (powertop output shown):
“CPUs” number 0 and 3 don’t run nearly as fast as the others. Powertop here is showing an average, but If I take snapshots of the frequency, the rest will run mostly around 2400 MHz (the nominal speed for the i5-1135G7), but 0 and 3 will more frequently bounce down to lower frequencies.
What’s particularly odd about it to me is that I’m pretty sure a “CPU” as exposed to Linux is really a hyperthreading thread, and the frequency only varies core by core, so it’s odd that powertop seems to show these “slow” CPUs being on different cores. It’s consistently 0 and 3 and maintains under load, so I don’t think it’s just cores not really doing anything.
I’m just wondering if anyone else has noticed this kind of behavior, really.
