CPU frequencies are kept in the kernel but they can be a little “off”. You can see them using:
$ cd /sys/devices/system/cpu
$ paste <(cat cpu*/cpufreq/affected_cpus) <(cat cpu*/cpufreq/scaling_cur_freq) | column -s $'\t' -t
0 833914
1 800021
2 800086
3 800029
4 800036
5 800460
6 800118
7 800141
If you don’t need to know the CPU #’s a shorter method is simply using:
$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
1396354
800058
800050
800024
800005
800017
