Hi!
CPU frequency in Windows and Linux is changing depending on task from 900MHz to 2.8GHz. but in FreeBSD can't see it.
Without powerd frequency not changed (always is 1.4GHz) and with powerd enabled changing in 3 steps: 1000, 1200 and 1400
My CPU is AMD Athlon Silver 3050e with 2 cores and 4 threads. the maximum frequency is 1.4GHz and boost frequency 2.8GHz.
some information from FreeBSD:
Please tell me about AMD CPU Frequency Control in FreeBSD.
