A CPU's clock speed represents how many cycles per second it can execute. Clock speed is also referred to as clock rate, PC frequency and CPU frequency. This is measured in gigahertz, which refers to billions of pulses per second and is abbreviated as GHz.
What is a good CPU frequency?
A clock speed of 3.5 GHz to 4.0 GHz is generally considered a good clock speed for gaming but it's more important to have good single-thread performance. This means that your CPU does a good job of understanding and completing single tasks.
Is CPU frequency important?
Clock speed is measured in GHz (gigahertz), a higher number means a faster clock speed. To run your apps, your CPU must continually complete calculations, if you have a higher clock speed, you can compute these calculations quicker and applications will run faster and smoother as a result of this.
