How to test the clock speed of my computer

Updated March 23, 2017

Clock speed is the frequency of your computer's central processing unit. This is also known as bus speed, because the front side bus is the mechanism that connects your CPU to the system memory. Clock speed determines how quickly your computer can perform basic calculations and functions. Clock speed is normally measured as a frequency in megahertz or millions of cycles per second. Multiple online clock speed tests are available online. However, windows has its own utility for testing clock speed.
