Alpha 21064
The Alpha 21064 is a microprocessor developed and fabricated by Digital Equipment Corporation that implemented the Alpha (introduced as the Alpha AXP) instruction set architecture (ISA). It was introduced as the DECchip 21064 before it was renamed in 1994. The 21064 is also known by its code name, EV4. It was announced in February 1992 with volume availability in September 1992. The 21064 was the first commercial implementation of the Alpha ISA, and the first microprocessor from Digital to be available commercially.
Alpha 21164
The Alpha 21164, also known by its code name, EV5, is a microprocessor developed and fabricated by Digital Equipment Corporation that implemented the Alpha instruction set architecture (ISA). It was introduced in January 1995, succeeding the Alpha 21064A as Digital's flagship microprocessor. It was succeeded by the Alpha 21264 in 1998. First silicon of the Alpha 21164 was produced in February 1994, and the OpenVMS, Digital UNIX and Windows NT operating systems were successfully booted on it.
AlphaServer
AlphaServer is a series of server computers, produced from 1994 onwards by Digital Equipment Corporation, and later by Compaq and HP. AlphaServers were based on the DEC Alpha 64-bit microprocessor. Supported operating systems for AlphaServers are Tru64 UNIX (formerly Digital UNIX), OpenVMS, MEDITECH MAGIC and Windows NT (on earlier systems, with AlphaBIOS ARC firmware), while enthusiasts have provided alternative operating systems such as Linux, NetBSD, OpenBSD and FreeBSD.
Alpha 21264
The Alpha 21264 is a Digital Equipment Corporation RISC microprocessor launched on 19 October 1998. The 21264 implemented the Alpha instruction set architecture (ISA). The Alpha 21264 is a four-issue superscalar microprocessor with out-of-order execution and speculative execution. It has a peak execution rate of six instructions per cycle and could sustain four instructions per cycle. It has a seven-stage instruction pipeline. At any given stage, the microprocessor could have up to 80 instructions in various stages of execution, surpassing any other contemporary microprocessor.
OpenVMS
OpenVMS (Open Virtual Memory System) anciennement VAX-11/VMS, VAX/VMS ou (officieusement) VMS est un système d'exploitation propriétaire créé par DEC en 1977 pour ses ordinateurs VAX. Le système a depuis été porté sur les processeurs DEC Alpha, et enfin Itanium. Hewlett-Packard Enterprise (HPE) détenait les droits sur OpenVMS jusqu'au , dont les dernières versions sont nommées OpenVMS, en raison de la présence d'une couche de compatibilité POSIX. C'est maintenant la société VMS Software, Inc.
DEC Alpha

(DEC), qui le commercialisa dans ses stations de travail et ses serveurs. La conception de ce processeur s’est très largement inspirée du processeur , ce dernier ayant connu de nombreux retards et ne sera finalement jamais commercialisé. Selon son fabricant Il sera notamment utilisé dans plusieurs superordinateurs Cray entre .
