Find CPU Speed and Number of Processors in Linux

All of the CPU information is stored in a file

less /proc/cpuinfo

or you can filter only the important information with

egrep  'GHz|MHz' /proc/cpuinfo

Example output will be

model name    : Intel(R) Core(TM) i5 CPU         650  @ 3.20GHz
cpu MHz        : 1200.000
model name    : Intel(R) Core(TM) i5 CPU         650  @ 3.20GHz
cpu MHz        : 1200.000
model name    : Intel(R) Core(TM) i5 CPU         650  @ 3.20GHz
cpu MHz        : 1200.000
model name    : Intel(R) Core(TM) i5 CPU         650  @ 3.20GHz
