There are basically three things that impact the clock speed of a CPU. Now that we’re up-to-speed with our CPU basics, let’s get into why your clock speed keeps running up and down. This is because the modern CPU can take advantage of multiple cores and improved programming that makes more efficient use of a slower base speed. It’s still important, but there are now factors that can change how powerful clock speed is.Ī modern CPU with a slower clock speed than a CPU from 5 years ago might still be faster. However, today’s multi-core processors have made the base CPU clock speed less vital than it once was. The clock speed of your CPU used to be one of the most important factors in the overall performance of your PC. Your CPU is basically the “brain” of your computer and the clock speed is how fast it can “think.” Every cycle handles a single basic equation and some can even handle multiple at once.

An Intel N5030 CPU with current clock speed of 2.31 Ghz the base frequency is 1.10 GHz and the burst is 3.10 GHzĮach of these cycles handles the basic mathematics that undergird the entirety of computing.
