GHz vs. MHz: Know the Difference
By Shumaila Saeed || Published on February 12, 2024
GHz (Gigahertz) and MHz (Megahertz) are units of frequency; 1 GHz equals 1,000 MHz.
Key Differences
GHz, short for Gigahertz, represents a billion cycles per second and is commonly used to measure the clock speed of computer processors. In contrast, MHz, which stands for Megahertz, denotes a million cycles per second and was more commonly used in older or less powerful technology.
