Q. How do I find out CPU information under AIX UNIX?

A. You can use graphical system administration tool for the IBM AIX computer operating system called SMIT.

AIX Commands

Following commands can be used.

lscfg command

lscfg - Displays configuration, diagnostic, and vital product data (VPD) information about the system including CPU information:
lscfg

Determining CPU Speed

When using AIX 5.1 and subsequent releases, the following code returns the processor speed in hertz (Hz):
lsattr -E -l proc0 | grep "Processor Speed"

Also, in AIX 5.1 pmcycles command lists the processor speed:
pmcycles

=> Read man page of pmcycles, lsattr, lscfg
