CPU frequencies are kept in the kernel but they can be a little β€œoff”. 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
800001
