- $ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

Display CPU frequency of Raspberry Pi |
We can also use vcgencmd command
- $ vcgencmd measure_clock arm
to display ARM processor's clock speed. IT will be something like:
frequency(45)=700000000
means 700,000,000 Hz or 700MHz - $ vcgencmd measure_clock core
to display system's core frequency, like:
frequency(1)=250000000
250,000,000 Hz, or 250MHz.
Display clock speed with vcgencmd command |
