You can use lscpu command or can view the file /proc/cpuinfo to get the CPU information from terminal.

Man page description of lscpu command:

lscpu gathers CPU architecture information like number of CPUs, threads, cores, sockets, NUMA nodes, information about CPU caches, CPU family, model and stepping from sysfs and /proc/cpuinfo, and prints it in human-readable format. 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.
