The Free On-line Dictionary of Computing (30 December 2018):

SPECmark89

    An old SPECmark benchmark result derived from
   a set of floating-point and integer benchmarks.  It is the
   geometric mean of ten SPEC ratios of the outdated 1989
   SPEC benchmark suite.  The use of SPECmark89 is strongly
   discouraged, having been superseded by CINT92 and CFP92.
