x86 | Vibepedia

x86, also known as the 8086 family, is a dominant family of Complex Instruction Set Computer (CISC) instruction set architectures (ISAs). Its lineage traces back to the 1978 [[intel-8086|Intel 8086]] microprocessor. The "x86" moniker emerged from the naming convention of its successors, such as the [[intel-80286|80286]], [[intel-80386|80386]], and [[intel-80486|80486]] processors. While often associated with [[ibm-pc|IBM PC]] compatibility, x86's influence predates and extends beyond the PC market, permeating embedded systems and general-purpose computing. As of 2022, x86-based processors, primarily from [[intel-corporation|Intel]] and [[amd|AMD]], still held a commanding share in the desktop and laptop markets, though facing increasing competition in other segments.
