List of former IA-32 compatible processor manufacturers

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.

Progressed into surviving companiesEdit

Product discontinued/transformedEdit

  • Harris Corporation – sold radiation-hardened versions of the 8086 and 80286; product line discontinued. Produced 20 MHz and 25 MHz 80286s (some motherboards were equipped with cache memory, which was unusual for 80286 processors).
  • NEC – sold processors, such as NEC V20 and NEC V30, that were compatible with early Intel 16-bit architectures; product line transitioned to NEC-designed architectures.
  • Siemens – sold versions of the 8086 and 80286; product line discontinued.

Left the market or closedEdit
