Main frequency

The main frequency is also called the clock frequency, and the unit is megahertz (MHz) or gigahertz (GHz), which is used to indicate the speed of the CPU's operations and data processing.

The main frequency of the CPU = external frequency × frequency multiplication factor. There is a certain relationship between the main frequency and the actual calculation speed, but it is not a simple linear relationship. Therefore, the main frequency of the CPU is not directly related to the actual computing power of the CPU. The main frequency indicates the speed at which the digital pulse signal oscillates in the CPU. In Intel's processor products, you can also see such an example: 1 GHz Itanium chip can perform almost as fast as 2.66 GHz Xeon / Opteron, or 1.5 GHz Itanium 2 is about 4 GHz Xeon / Opteron As fast. The operation speed of the CPU depends on the performance indicators of the CPU such as the pipeline, bus, etc.
