I am seeing the same error but for cpu when I do something that maxes out the CPUs (like run a cinebench multi-core benchmark reproduces 100% for me). I am on a MacStudio non-ultra running Ventura 13.4.1.

I think it is because the power clusters are showing nan's in powermetrics:

@tlkh please check the above linked PR, it solves this

Seeing exact same issue on an M4 when running in low power mode.

Repro Steps

• Set computer to low power mode
• Run a workload that maxes out any performance core
