What is CPU usage? The processor, also known as the central processing unit (CPU) is arguably the most important component inside any computer.

If your PC has slowed down, high CPU usage may be the cause. In this guide, we will show you how to check your CPU usage and how to fix it when it's too high.

What Is CPU Overhead?. CPU overhead measures the amount of work a computer's central processing unit can perform and the percentage of that capacity that's used by individual computing tasks.

CPU speeds are measured in GHz, but they don't tell the full story of a processor's performance, multi-tasking capability, and other computing features.

An APU combines the CPU and GPU into a single package, helping save space and even power. But there are a few downsides to keep in mind too.

From the CPU's perspective, a thread (short for "thread of execution") is merely an ordered sequence of instructions that tells the computer what to do.

We discuss the ideal CPU utilization when gaming. High CPU utilization can burn your system's internals, whereas low CPU utilization is due to bottlenecking of components.

A CPU's operating temperature will rise if the cooling fan breaks, dramatically increasing the chance of hardware failure. Stock modern computer CPUs use a two-part CPU cooler that features a ...
