What is the dominant frequency in the computer? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The main frequency is the clock frequency of CPU. The operation of the computer is carried out step by step under the control of the clock signal, and each clock signal cycle completes one-step operation. The clock frequency reflects the speed of CPU to a large extent.

The main frequency of CPU does not represent the speed of CPU, but increasing the main frequency is very important to improve the speed of CPU operation. For example, if a CPU executes an operation instruction in a clock cycle, CPU will be twice as fast when running on the 100MHz main frequency as it is running on the 50MHz main frequency. Because the clock cycle of 100MHz is half the clock cycle time of 50MHz, that is, the time required by CPU working at 100MHz main frequency to execute an operation instruction is only half that of 10ns, which is half that of 20ns working at 50MHz main frequency, and the natural operation speed is twice as fast. However, the overall running speed of the computer depends not only on the CPU operation speed, but also on the operation of other subsystems. only when the main frequency is increased, the running speed of each subsystem and the data transmission speed between the subsystems can be improved, can the overall running speed of the computer be really improved.

The improvement of the working frequency of CPU is mainly limited by the production process. Because CPU is made on semiconductor silicon wafer, wires are needed to connect the elements on silicon wafer. Under the condition of high frequency, wire is required to be as thin as possible. Only in this way can stray interference such as wire distributed capacitance be reduced to ensure correct CPU calculation. Therefore, the limitation of manufacturing process is one of the biggest obstacles to the development of CPU main frequency.
