When choosing a computer and its components, they usually pay attention to the following characteristics: the power of the video card, the amount of RAM and hard drive, as well as the frequency of the processor. The latter value is one of the main indicators on which the operation of the entire computer depends.
The central processing unit (central processing unit or CPU) is an electronic unit or microcircuit that executes machine instructions (program codes) and is the main part of the computer hardware or programmable logic controller. Sometimes it is also called a processor or microprocessor. One of its main characteristics is its clock frequency. The speed of work depends on it, as well as the "Response" time of the device. Accordingly, the higher the frequency (from 900 to 3800 MHz), the faster the entire computer will work. Clock speed is the number of clock cycles (operations) that a processor can perform per second. It is proportional to the bus frequency. As a rule, its performance directly depends on the size of the processor's clock frequency. But this statement is only relevant for models of one line, since other parameters also affect processor performance, for example, the size of the second-level cache, the frequency and availability of the third-level cache, special instructions, and so on. The clock frequency can also be defined as the clock frequency of the electronic synchronous circuit. which enter the system from the outside in one second. This parameter characterizes the performance of the subsystem, that is, the total number of operations performed per second. Of course, a lot depends on this value, since it directly affects the computer's performance. But you need to understand that different processors have their own capabilities, advantages and disadvantages at the same core frequency. In addition, the processor interface blocks operate at the motherboard's clock speed, which can be much lower than the processor's frequency. Also, the declared frequency value does not always really reflect the real picture, since it happens that manufacturers indicate a higher frequency, which refers to a similar processor from another company.
