The chip and the CPU are both very important parts of a computer, but they do have differences. Chip is a small integrated circuit, usually we refer to the chip is a very high integration of the chip, such as processor chip, memory chip and so on. The CPU, Chinese for central processing unit, is one of the core components of the computer, responsible for executing instructions and controlling the operation of the computer.

The CPU is a kind of chip, but the CPU is a more special processor than the chip. CPU is the heart of the computer, is the main part of the execution of instructions, all of its operations are supported by the chip. The higher the integration of the chip, the more it can meet the needs of complex operations, which can greatly improve the speed of computer processing data.

In addition, the chip also includes a large number of other electronic devices, such as capacitors, resistors, and so on. The design and production process of the chip is very complex, and it needs to go through many integrated design and processing procedures to produce the finished product. Relatively speaking, the CPU is relatively compact, the structure is relatively single, mainly composed of several modules.

In the history of computer development, the functional range of cpus has also changed dramatically. The CPU was originally composed of a simple clock and counter, with the continuous progress of technology and theory, the structure of modern cpus has become very complex, and even has multi-core performance, which greatly increases the processing speed and capability of the computer.

In short, chips and cpus are crucial components in a computer. However, chips have a wider range of applications, and the CPU is one of the most important components in the computer, whose role is to control all the operations of the computer, so the impact on computer performance is very important.
1. Functional differences:
< br >
The functions of cpu are sequence control, operation control, time control, data processing, interpretation of computer instructions, and processing of data in computer software. All operations in the computer are the core parts of the CPU that are responsible for reading instructions, decoding instructions and executing instructions.
< br >
The function of the chip is to provide support for the type and frequency of the CPU, the type and maximum capacity of the memory, ISA\/PCI\/AGP slot, ECC error correction and so on.

2. Different composition:
< br >
Chip refers to the electronic logic gate circuit burned to the silicon chip with laser, thus forming a variety of chips, today's highest integration, the most powerful should be the CPU chip. CPU refers to all periods, a variety of electronic components of the computer central processing unit collectively.

3. Different definitions:
< br >
In electronics, chips are a way to miniaturize circuits (mainly including semiconductor devices, but also including passive components, etc.), and are usually manufactured on the surface of semiconductor wafers, integrated circuit blocks are called, memory does not change abnormally means that this type of memory is not required to constantly maintain energy.
< br >
cpu is one of the main equipment of the electronic computer, the core accessories in the computer.

4, production composition is different:
< br >
The preparation of the chip mainly depends on the micro-machining, automation and chemical synthesis technology, and the CPU includes the arithmetic logic component, the register component, the arithmetic device and the control component.
