What is cpu turbo?

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

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

CPU anti-counterfeiting guide:

1. Look at the serial number. It is also valid for Intel and AMD processors. Each genuine boxed processor has a unique number. This number will be marked on the barcode on the product box and on the surface of the processor. This number is equivalent to the IMEI code of the mobile phone. , if you find that the two serial numbers are different after purchasing the processor, then you can be sure that the product you bought has been switched by an unscrupulous merchant.

2. Look at the packaging. Appearing on Intel's CPUs, the difference between Intel's boxed processors and loose-pack processors is the three-year warranty, and the price difference ranges from tens to hundreds of dollars. Of course, AMD boxed products are also full of fakes, especially Sempron 2500 and E6 3000.

3. Look at the fan. For Intel processors, after opening the package of the CPU, you can check the anti-counterfeiting label in the center of the original fan. The anti-counterfeiting label on the real Intel box package CPU is three-dimensional anti-counterfeiting. In addition to the changes in the underlying pattern, there will also be a three-dimensional "Intel" logo. As for the fake boxed CPU, its anti-counterfeiting mark only changes the underlying pattern, without the "Intel" logo, and the heat sink is very sparse.

Extended information

Main functions of CPU

1. Process instructions. It refers to the execution sequence of instructions in the control program. There is a strict sequence between the instructions in the program, and they must be executed strictly in the order specified by the program to ensure the correctness of the computer system.

2. Perform the operation. The function of an instruction is often implemented by a series of operations performed by components in the computer. The CPU should generate corresponding operation control signals according to the function of the instruction and send them to the corresponding components, thereby controlling these components to act according to the requirements of the instruction.

3. Control time. Time control is to implement time timing for various operations. During the execution of an instruction, what operations are performed at what time should be strictly controlled. Only in this way can the computer work in an orderly manner.

4. Process data. That is, perform arithmetic operations and logical operations on data, or perform other information processing. Its function is mainly to interpret computer instructions, process data in computer software, and execute instructions. In a microcomputer, it is also called a microprocessor. All operations of the computer are controlled by the CPU. The performance indicators of the CPU directly determine the performance indicators of the microcomputer system.

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