Whether you are on a long trip and would like to conserve power, or you love playing video games and would like to boost your performance, it is good to have more control over your CPU. If you use GNOME, you will be familiar with the new performance settings in the panel, but there it does not provide the most control. If you would like to be able to easily tweak your CPU to the very last core, cpupower-gui is an amazing graphical utility for managing your CPU. I am going to show you how to install it, and how you can use it to configure your CPU settings.
