Intel, AMD, and Cyrix have always used codenames when talking about future processors. The codenames usually are not supposed to become public, but they typically do. They can often be found in online and print news and magazine articles talking about future-generation processors. Sometimes, they even appear in motherboard manuals because the manuals are written before the processors are officially introduced. Table 3.23 lists processor codenames for reference purposes.

Note that the codenames and information listed in these tables are used before the processor is officially introduced. After a chip is introduced, the codename is dropped and the chip is thereafter referred to by the marketing name used at the time of the introduction. Because many of these names refer to chips that are not yet officially released, the names or specifications might change. For chipset codenames, see Chapter 4.
