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.
