List of former IA-32 compatible processor manufacturers explained

As the 32-bit Intel Architecture became the dominant computing platform during the 1980s and 1990s, multiple companies have tried to build microprocessors that are compatible with that Intel instruction set architecture. Most of these companies were not successful in the mainstream computing market. So far, only AMD has had any market presence in the computing market for more than a couple of product generations. Cyrix was successful during the 386 and 486 generations of products but did not do well after the Pentium was introduced.

List of former IA-32 compatible microprocessor vendors:

Progressed into surviving companies

Product discontinued/transformed

Left the market or closed

Incomplete/unsuccessful projects
