InsightsLeave a comment

The easiest way to check CPU speed and CPU model on Linux is to issue the below command from the CLI.

bash

  1. more /proc/cpuinfo | egrep 'model name|cpu MHz'

This will return results like the below that will list CPU model name on one line followed by CPU speed on the next line.

bash

  1. [root@server ~]# less /proc/cpuinfo | egrep 'model name|cpu MHz'
  2. model name : Dual-Core AMD Opteron(tm) Processor 2212
  3. cpu MHz : 2010.302
  4. model name : Dual-Core AMD Opteron(tm) Processor 2212
  5. cpu MHz : 2010.302
  6. model name : Dual-Core AMD Opteron(tm) Processor 2212
  7. cpu MHz : 2010.302
  8. model name : Dual-Core AMD Opteron(tm) Processor 2212
  9. cpu MHz : 2010.302
