The main frequency, also known as clock frequency, is measured in MHz and is used to represent the CPU’s computational speed. CPU’s main frequency=external frequency × Octave frequency coefficient.
Many people believe that the main frequency determines the running speed of the CPU, which is not only one-sided, but also biased towards industrial control computers (shop. evoc. cn). So far, there is no definite formula that can achieve a numerical relationship between the main frequency and the actual computing speed. Even the two major processor manufacturers, Intel and AMD, have great controversy on this point. From the development trend of Intel’s products, we can see that Intel attaches great importance to strengthening the development of its own main frequency. Like other processor manufacturers, someone once compared one 1G Transmeta to another, and its operating efficiency is equivalent to 2G Intel processors. So, the main frequency of the CPU is not directly related to its actual computing power, as it represents the speed at which digital pulse signals oscillate within the CPU. In Intel’s processor products, we can also see examples where a 1 GHz Itanium chip can perform almost as fast as a 2.66 GHz Xeon/Opteron, or a 1.5 GHz Itanium 2 can perform approximately as fast as a 4 GHz Xeon/Opteron. The computing speed of the CPU also depends on various performance indicators of the CPU’s pipeline. Of course, the main frequency is related to the actual computing speed, and it can only be said that the main frequency is only one aspect of CPU performance, and does not represent the overall performance of the CPU.
