Adamo Since MacMission Control's November 7 invitation to run the Whetstone benchmark on your PC, over 100 scores have been reported. Thanks to all who contributed! Number-crunching performance on more than 50 distinct hardware configurations, from a PowerBook 170 to a Power Macintosh 9600/350, are now documented at the following URL. <http://www.MacMissionControl.com/~MMC/> Additional scores in this database continue to support the observation, made in November 7's post, that Power PC processors under Mac OS will out-perform x86 and Pentium processors under Windows by a factor of 2-to-1 at a given clock speed. The Wintel world simply cannot compete with Power PC and Mac OS because it's shackled to the x86 CISC instruction set. Under Linux, one 80686 processor demonstrated a 40% improvement with respect to its Windows score, but the improvement was to a level only two-thirds that of Power PC processors running at the same clock speed. Several scores using the new "G3" 750 processors were reported. Optimized for integer arithmetic, these chips aren't expected to deliver Whetstone scores as high as comparable 604e processors. While measureable under benchmark conditions, this performance gap may not be perceivable in practice. At a given clock speed, the difference between a 604e and a 750 is perhaps one-quarter that between a 604e and a 603e. |
