A gigahertz (GHz) is a unit of frequency in the International System of Units (SI), equal to one billion hertz (109 Hz). The plural form is gigahertz.
The gigahertz measurement is famously used to indicate a computer's CPU clock speed, which tells you how many processing cycles it can complete per second.
For example, a 3.2 GHz processor can handle 3.2 billion cycles every second.
While a higher GHz number often suggests a faster processor, overall performance also depends on other critical factors, such as the number of cores and the chip's architecture.
Your daily wireless connections, like Wi-Fi and Bluetooth, operate on specific gigahertz frequency bands.
The most common Wi-Fi bands are 2.4 GHz and 5 GHz.
Each has its own strengths:
Similarly, 5G mobile networks use various GHz frequencies to deliver the ultra-fast data transmission that powers modern mobile devices.
Focusing solely on gigahertz to judge a processor's performance is a common mistake known as the "gigahertz myth."
A processor with a lower clock speed but a more efficient design (e.g., more cores, a larger cache, or better instructions per cycle) can easily outperform a processor with a higher GHz rating.
This is why comparing processors requires looking at a combination of specifications, not just the clock speed.
