The current CPU speed of 4.34 GHz along with the base speed listed at 3.70 GHz Take my simple Asus Chromebook for example – it has a 4-core CPU, and it’s CPU clock speed constantly changes: Modern CPUs like Intel Turbo Boost and AMD Precision Boost can increase the speed of your CPU, either across a single core – or multiple cores.Īnd this is the most common reason that the CPU speed is constantly changing, especially on a newly built (or purchased) PC which hasn’t been subject to heavy running yet. Your PC hardware likely came with software or firmware that can automatically boost the speed of your CPU.
Overclocking used to be the work of dedicated PC performance buffs, but it now comes standard in most PC packages. Here’s a more detailed explanation of those factors, and whether you even need to do anything to regain control of a runaway CPU (not all CPU frequency changes are a bad thing, after all).
Automatic performance boosts, overclocking, and thermal throttling are the big factors that can raise, or lower, your CPU clock speed. 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.
