The '''iAPX 432''' (''Intel Advanced Performance Architecture'') is a discontinued [[computer architecture]] introduced in 1981.<ref name="dvorak">{{cite web|url=http://www.dvorak.org/blog/whatever-happened-to-the-intel-iapx432|access-date=19 July 2012|title=Whatever Happened to the Intel iAPX432?|last1=Dvorak|first1=John C.}}</ref>{{refn|group=NB|Sometimes ''Intel Advanced Processor Architecture''<ref>{{cite book |title=Defining Intel: 25 Years / 25 Events |date=1993 |publisher=Intel |page=14 |url=https://www.intel.com/Assets/PDF/General/25yrs.pdf}}</ref>}} It was [[Intel]]'s first [[32-bit]] [[Microprocessor|processor]] design. The main processor of the architecture, the ''general data processor'', is implemented as a set of two separate integrated circuits, due to technical limitations at the time. Although some early 8086, 80186 and 80286-based systems and manuals also used the [[iAPX]] prefix for marketing reasons, the iAPX 432 and the 8086 processor lines are completely separate designs with completely different instruction sets.

The project started in 1975 as the '''8800''' (after the [[Intel 8008|8008]] and the [[Intel 8080|8080]]) and was intended to be Intel's major design for the 1980s. Unlike the [[Intel 8086|8086]], which was designed the following year as a successor to the 8080, the iAPX 432 was a radical departure from Intel's previous designs meant for a different market niche, and completely unrelated to the 8080 or [[x86]] product lines.

The iAPX 432 project is considered a commercial failure for Intel, and was discontinued in 1986.<ref name="dvorak"/><ref>{{cite web|last1=Smith|first1=Eric|title=Intel iAPX-432 Micromainframe|url=https://www.brouhaha.com/~eric/retrocomputing/intel/iapx432/|access-date=Dec 6, 2015|archive-date=February 2, 2016|archive-url=https://web.archive.org/web/20160202195456/http://www.brouhaha.com/~eric/retrocomputing/intel/iapx432/|url-status=dead}}</ref>
