Frequently Asked Questions
It is both singular and plural. You say 'one gigahertz' and 'ten gigahertz'. The form does not change.
MHz stands for megahertz (million hertz) and GHz stands for gigahertz (billion hertz). 1 GHz = 1000 MHz.
Not always. While a higher clock speed (GHz) is generally better, overall performance also depends on the processor architecture, number of cores, and other factors.
Yes. Gigahertz is used in any field dealing with high-frequency waves, such as radio communications, astronomy, and medical imaging (e.g., MRI).
