   VAX MIPS
   VUP
      <benchmark> (Or VAX Unit of Performance, VUP) The processing
      power normally attributed to a Digital Equipment Corporation
      VAX 11/780.  Future VAX systems were rated according to this
      scale (e.g. VAX 8350's being 2.7 VUPs per CPU).  A MicroVAX
      II is normally associated with 0.9 VUPs and at a later time
      the MicroVUP was coined to rate VAX workstations.  The use
      of the VUP by Digital Equipment Corporation has been replaced
      with more standard benchmarks (SPECint and SPECfp) in the
      DEC Alpha processor systems.
