We used a SPARCstation 5 Model 70 rated at 60 SPECint92 and 47 SPECfp92
, and a GNU C++ compiler set for maximum optimization (-03).
In recognition of the demand for aggregate result numbers, composite values are deflned as: SPECint92 = the geometric mean of the six SPEC ratios from CINT92; and SPECfp92
= the geometric mean of the 14 SPEC ratios from CFP92.
With estimated performance values of 75 SPECInt92 and 85 SPECfp92
, the 603 is comparable in performance to present-day high-end personal computer and workstation processors.
