The Specmark comes from an industry consortium which includes workstation
vendors such as Sun, IBM, HP and Intel. This benchmark is a composite
of the results of 10 different tests. The idea is that the Specmark
suite is less susceptible to benchmark "cheating" than the Dhrystone-based
MIPS benchmark. Others complain however, that is more weighted in favor of
floating-pt. performance vs. integer performance, so Intel branched off
and created the I Spec or Integer Specmark.
In any case here is some data:
