Linux – Find Out CPU Architecture Information

You can use /proc/cpuinfo file or use the lscpu command to get info about CPU architecture.

It will display information like:

Number of CPUs
NUMA nodes
Information about CPU caches,
CPU family, model and stepping.

Alternatively, it can print out in parsable format including how different caches are shared by different CPUs, which can also be fed to other programs.

Open a terminal and type the following command:

$ less /proc/cpuinfo


$ lscpu

Samp-le outputs:
