This little tool will let you know most of the info about your CPU:
The CPU name, type and manufacturer, the cache sizes, all the different
instructions that the CPU supports and all the different functions, and
a lot of information about the CPU cache system.

What's New:

Added command line commands (read ReadMe.txt for more info).
Full support of all currently available Intel and AMD CPUs (including upcoming FX-60).
Added AMD64 TCaseMax/TDP detection in the "Power management" section, simply hit F9 if you have an AMD64 tech chip.
A lot of other updates and bug fixes that I can't even remember.
"Add Memory divider on-the-fly control for AMD64 CPUs" - Now available as a standalone app
