For some computer novices, they may not know much about cpu main frequency, so they need to pay more attention to the knowledge of computer hardware.So what is the meaning of cpu main frequency and what are the parameters of cpu main frequency?Let's take a look at it next.

What is the meaning of cpu main frequency

In fact, the higher the cpu main frequency, the better.Many users think that the cpu main frequency is the representative of the computer's operating speed, in fact, it is not so, cpu main frequency mainly indicates the speed of the pulse signal oscillation of the comb inside the cpu, it only indirectly will have an impact on its computing speed, but not absolutely.
Sometimes under certain circumstances, it is possible for a CPU with a higher main frequency to have a lower actual computing speed.Although cpu main frequency is one of the important factors to measure the goodness of a computer, but we can not just go for high cpu main frequency when buying a computer.In addition to looking at the cpu frequency, you should also consider the configuration information of other hardware and software when purchasing.Then a comprehensive evaluation of the performance of the machine, so that you can buy a more cost-effective laptop.

What is the meaning of multiplier factor

The main frequency of the cpu has a certain ratio (multiplier) to the external frequency, because the operating frequency of the memory and the L2Cache set on the motherboard is synchronized with the external frequency of the cpu, so the overall performance of a computer assembled with a cpu with a high external frequency is higher than that of a cpu with the same main frequency but with a lower external frequency.This parameter is related to the choice of motherboard.
The multiplier factor is the proportional relationship between the main frequency and the external frequency of the cpu, generally: main frequency = external frequency * multiplier. all cpus of Intel (with the exception of a few test products) are usually locked (frequency lock), the user can not adjust the multiplier to adjust the main frequency of the cpu, but can still adjust the external frequency to set a different main frequency. cpus of AMD and other companies are not locked.
