CPUPower-GUI is a simple graphical utility allows to change the frequency limits of your cpu and its governor.
With the tool, you can easily change the frequency settings based on CPU core by adjusting the sliders and clicking apply button.
You can also change the cpu governor profiles, Performance and Balanced. And the profiles can be selected easily from the system tray indicator menu.
The software also offers an option to enable or disable a specific cpu via the online checkbox. If this checkbox is greyed-out, it means that this cpu is not allowed to go offline.
