Librem5 MMS Question

Are the photos in this post up-to-date?

I would like to know what is the true speed of the CPU, since some say 1.2 GHz and others say 1.15 GHz. Can you make the phone do something that will make the processor run at its top speed and then enter this command in the terminal:
cat /proc/cpuinfo

What does it say under cpu MHz?
