The main frequency, CPU frequency and clock frequency are important concepts in computers, which determine the running speed of computers.The unit is Hertz (Hz), which represents the number of synchronization pulses that occur within one second during CPU operation.
With the development of computers, the main frequency has developed from M360 Hz to GHZ (1G=1024M).In the same series of microprocessors, the higher the main frequency, the faster the computer speed.However, between different types of processors, the main frequency is only a reference parameter.
In addition to the main frequency, the CPU's operation speed is also affected by other performance indicators such as pipeline indicators.Therefore, it is not always possible to judge the overall performance of a processor by looking only at the main frequency.
Double frequency and external frequency are important concepts closely related to the main frequency.External frequency is the reference frequency of CPU, and the unit is MHz.The frequency multiplication is a multiple of the ratio of the main frequency to the external frequency.At present, in most computer systems, the internal and external frequencies also run synchronously with the memory.In this way, it can be understood that the external frequency of the CPU is directly connected to the memory, and the synchronization between the two is achieved.
To sum up, when considering computer performance, it is necessary to comprehensively consider multiple factors, including main frequency, double frequency, external frequency, etc.
According to my experience with mobile phones.The Snapdragon's CPU consumes a lot of power but runs very fast. The MTK's running speed is not slow, nor does it consume much power. But its life span is much worse than that of the Snapdragon.The same is true for the 4-core mobile phone HZ. I believe the Snapdragon can be durable.
