CPU means Central Processing Unit, which is the central processing unit, which is the most critical and core part of the computer. It represents the performance of the computer and also determines the price of the computer to a great extent.
The CPU contains logic components, registers and control components. The logic component is the part of the CPU used for calculations. Because electronic circuit components use binary logic operations, they are called logic components. Registers are where data is temporarily stored. The CPU is performing a large number of operations. If there is no certain storage space to support it, the operations will not be performed and the results will be lost. The control component is the component that controls the logic components and registers to coordinate the work, and is the brain of the CPU.
The so-called computer is a machine that can perform a large number of calculations in a short time. The CPU is its core component. The central processing unit mainly includes a computing unit, which is a very large-scale integrated circuit. Supercomputers can perform more than one quadrillion calculations per second, all thanks to the arithmetic units. The efficiency of the CPU is often expressed by the main frequency. The commonly used unit for main frequency is GHz. Generally, the main frequency of CPU can reach 2-2.5GHz, which is the mainstream computing power in the market. This kind of CPU includes AMD's high-end series, Core I5 low-voltage series, etc., which can probably be accelerated to more than 3GHz with turbo frequency, but generally it will not exceed 3.5 GHz.
CPU has such high computing performance, which is naturally accompanied by quite high heat production. Where the computer is close to the CPU and graphics card, the surface temperature can reach 46 degrees Celsius or even higher. Therefore it is very important to cool down the CPU. In a computer, the CPU will have a small fan attached to it to cool the CPU. Overheating of the CPU may cause the computer to crash, or even cause the motherboard to burn out, or even cause a fire. Therefore it is also very important to use computers in moderation.
