In this issue, the editor will bring you about what is cpu turbo. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

The Turbo Boost acceleration technology of computer CPU, which is based on the power management technology of Nehalem architecture, intelligently shuts down some unused cores intelligently by analyzing the current CPU load, leaving energy to the cores that are in use, and making them run at higher frequencies to further improve performance.

On the contrary, when multiple cores are needed, the corresponding cores are opened dynamically and the frequency is intelligently adjusted. In this way, the core operating frequency can be set higher without affecting the TDP (thermal power design) of the CPU.

CPU Anti-counterfeiting Guide:

1. Look at the number. For Intel and AMD processors are also effective, each genuine boxed processor has a unique number, in the product box on the bar code and processor surface will be marked with this number, this number is equivalent to the phone's IMEI code, if you buy the processor after finding that the two numbers are not the same, then you can be sure that you bought this product has been replaced by illegal businessmen.

2. Look at the packing. Appear on Intel's CPU, the difference between Intel boxed processors and bulk processors lies in the three-year warranty, the price difference varies from tens to hundreds of yuan. Of course, AMD boxes are also full of fakes, especially Flash Dragon 2500 + and E63000+.

3. Look at the fan. For the Intel processor, after opening the packaging of the CPU, you can view the anti-counterfeiting label in the middle of the original fan, the real Intel package CPU anti-counterfeiting label is three-dimensional anti-counterfeiting, in addition to the underlying pattern will change, there will also be a three-dimensional "Intel" logo. And the fake box CPU, its anti-counterfeiting logo only the underlying pattern changes, there is no "Intel" logo, and the heat sink is very sparse.

Extended data

Main functions of CPU

1. Processing instructions. Refers to the order in which instructions are executed in the control program. There is a strict order between the instructions in the program, which must be carried out in strict order in order to ensure the correctness of the work of the computer system.

2. Perform the operation. The function of an instruction is often realized by a series of operations performed by components in the computer. According to the function of the instruction, CPU should generate the corresponding operation control signal and send it to the corresponding components, so as to control these parts to act according to the requirements of the instruction.

3. Control time. Time control is the timing of various operations. During the execution of an instruction, what to do at any time should be strictly controlled. Only in this way can the computer work methodically.

4. Processing data. That is, to carry on the arithmetic operation and logical operation to the data, or carry on other information processing. Its main function is to interpret computer instructions and process data in computer software, and execute instructions. In a microcomputer, which is also called a microprocessor, all operations of the computer are controlled by CPU. The performance index of CPU directly determines the performance index of the microcomputer system.

CPU has the following four basic functions: data communication, resource sharing, distributed processing, and providing system reliability. The operation principle can be divided into four stages: extraction, decoding, execution and write-back.

The above is the editor for you to share what is cpu turbo, if you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
