(benchmark)
Results for each individual benchmark of the SPEC benchmark suites, for example CINT92 and CFP92, expressed as the ratio of the wall clock time to execute one single copy of the benchmark, compared to a fixed "SPEC reference time", which was chosen early-on as the execution time on a VAX 11/780.
