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[edit]

Product discontinued/transformed[edit]

  • Harris Corporation – sold rad-hard versions of 8086 and 80286; product line discontinued. Produced 20 MHz and 25 MHz 80286 cpus (some motherboards were equipped with cache RAM, which was unusual for a 286 class chip)
  • NEC – sold early Intel architecture compatibles such as NEC V20 and NEC V30; product line transitioned to NEC internal architecture
  • Siemens – sold versions of 8086 and 80286; product line discontinued.
