Dear Elmer: They supplied the switches in their submission to SPEC. I assume they used the SAME output for both CPUs. I think that most of the "Improvement" is due to the compiler and not the CPU. Have you seen any benches with older compiler on Coppermine. All of the ones I have seen are with the new compiler. 512K of L2 has been shown to have an effect on some programs where a Pentium III outruns a Celeron on same software. Perhaps the older compiler optimised for a half speed cache of 512K and this hurts the Coppermine. That is why Intel does not release a benchmark using the older version. A third party might resolve this if they benched a Coppermine with the older compiler (Intel Fortran v2.4 or C/C++ v4.0)? In any case, most software is not compiled with the v4.5 compiler. Most Commercial users would not use a compiler that restricts the CPU. (Too many K6/Athlons out there). Pete
