CPU ClockSpeed

CPU ClockSpeed is a lightweight widget that displays the current clockspeed of your computer's CPU, right in the sidebar. It can be seamlessly installed and configured, even by users with less or no experience in software applications.
The interface of the tool is represented by a very small frame that you can move to any spot on the desktop, with the help of the mouse cursor.
CPU ClockSpeed doesn't pack any extra features. However, several customization options can be made from the Settings screen.
For instance, you can select one of the 16 available skins for the UI, pick a different refresh speed from a drop-down menu, as well as make CPU ClockSpeed display the clockspeed in GHz, instead of MHz.
Thanks to the default settings provided by the operating system, you can adjust the frame's opacity level (between 20% and 100%) as well as make it stay on top of other windows.
The lightweight tool does not put a strain on the computer's resources, since it runs on a very small amount of CPU and system memory. No error dialogs have popped up during our testing and CPU ClockSpeed did not hang or crash. However, a weak point of the tool lies within its response time, whether we are talking about key strokes or mouse commands. We must also take into account the fact that CPU ClockSpeed has not been updated for a very long time. Other than that, the app can be easily handled, even by inexperienced users.
