Intel was founded in 1968. In just over 20 years, it has made remarkable achievements. In 1971, the world’s first microprocessor was introduced. In 1981, IBM launched the world’s first IBM PC using Intel’s 8088 microprocessor. In 1984, it was selected as one of the 100 most worthy companies in the United States. In 1992, it became the largest in the world. Semiconductor integrated circuit manufacturers, in 1994 its turnover reached 11.8 billion US dollars, about 80% of the CPU market share. Intel leads the CPU world trend, from 286, 386, 486, Pentium, short-lived Pentium Pro, Pentium II, Pentium III to the current mainstream Pentium 4, which has always promoted the replacement of microprocessors. Intel's CPU not only has excellent performance, but is also ideal for stability and power consumption.

AMD was founded in 1969 and its head office is located in Silicon Valley, USA. It is an integrated circuit supplier that provides a variety of chip products for the computer, communications and consumer electronics markets, including microprocessors, flash memory, and silicon-based solutions for communications and networking equipment. AMD is the only CPU manufacturer that can compete with Intel. AMD's products have now formed a series of products centered on Athlon XP, Duron, Sempron, and Athlon 64. AMD believes that with the advantages of the CPU core architecture, AMD processors with the main frequency have better overall performance. However, the heat output of the AMD early processors is often relatively large. The current new products are concerned about the heat generation problem. Now, this issue in the products does not require much attention. At the same time, because the product has been supported by many partners and many complete machine manufacturers, the problem of poor compatibility in early products has been basically solved. AMD's products are characterized by high performance and low price.

The VIA Cyrix III (C3) processor is produced by VIA. Its biggest feature is its low price, performance and practicality, and it is very attractive to economically stressed users.
