How to Determine the CPU Speed in Windows

Although there is no single number that can truly define the performance of a computer, many people rely on the speed of their CPU as a gauge. If you would like to use your CPU speed to compare computers, most versions of Windows allow you to accomplish this with a few clicks. Use the System Properties screen in Windows XP or later to determine the speed of your computer's CPU.

Instructions

(If you do not see this icon, click the "Classic View" link on the left side of the window in Windows XP and Vista or "View by: Small icons" at the top of the window in Windows 7.) The speed of the processor is shown on this screen, generally under a category labeled "Processor" or "Computer." Look for a reading such as "2.20 GHz."
