'''Alpha''' was a family of {{arch|64}} [[Alpha]]-based performance microprocessors designed by [[DEC]] and introduced in [[1992]].

== Overview ==
Introduced in late 1992, Alpha was a family of microprocessors designed for high-end desktops, workstations, and servers. At their introduction, those chips were the world's fastest, though their competitiveness dropped at later iterations (though some attributed this to Alpha's acquisition by Compaq in [[1998]]). Alpha CPUs have gone through a handful of microarchitectures, each improving performance and capabilities.
