* First x86 chip to handle [[32-bit computing|32-bit]] data sets
* Reworked and expanded memory protection support including [[Paging|paged virtual memory]] and virtual-86 mode, features required at the time by [[Xenix]] and [[Unix]]. This memory capability spurred the development and availability of [[OS/2]] and is a fundamental requirement for modern operating systems like [[Linux]], [[Windows]], and [[macOS]]
* First used by Compaq in the [[Compaq Deskpro 386|Deskpro 386]]. Used in desktop computing
* Unlike the DX naming convention of the 486 chips, it had no math co-processor
* Later renamed Intel386&nbsp;DX
