Joe <edited> could you you run me through your numbers because I, frankly, do not see how you got to your conclusion. we can equally compare dP/df to dP/df or dP/dQf to dP/df Let's be conservative (against AMD) and use the 2nd. sandra 2002 MM yields no difference considering how much of a difference especially considering what a bios upgrade made ( dP/df to dP/df in amd's favor ) SiSoft Sandra 2002 Pro Multimedia Bench FLOAT AthlonXP Qf f(GHz) score DP/Df dP/df dP/dQf 2100+ 1.733 11123 6.42E+03 6.42E+03 4.30E+03 2000+ 1.666 10693 6.42E+03 6.47E+03 4.27E+03 1900+ 1.600 10266 6.42E+03 6.37E+03 4.27E+03 1800+ 1.533 9839 6.42E+03 6.34E+03 4.25E+03 1700+ 1.466 9414 6.42E+03 6.50E+03 4.29E+03 1600+ 1.400 8985 6.42E+03 6.43E+03 4.31E+03 1500+ 1.333 8554 6.42E+03 n/a n/a Northwood f(GHz) score DP/Df dP/df 2.200 10795 4.91E+03 4.89E+03 2.000 9818 4.91E+03 4.93E+03 1.800 8833 4.91E+03 4.87E+03 1.600 7859 4.91E+03 n/a Let's look at p4 to p4; NW is definitely faster but the scaling derivative is not a nicely defined function to begin with just look at: Willamette f(GHz) fps DP/Df dP/df 2.000 52.4 26.20 17.00 1.900 50.7 26.68 13.00 1.800 49.4 27.44 22.00 1.700 47.2 27.76 18.00 1.600 45.4 28.38 20.00 1.500 43.4 28.93 16.00 1.400 41.8 29.86 n/a Having said that, I say that my knowledge of processors is close to zero but from stand point of pure math I do not see how you arrived to your conclusion - I am sure I am missing something Regards -Albert ps sandra overall yields even less conclusive results Sysmark 2002 (overall score) AthlonXP Qf f(GHz) score DP/Df dP/df dP/dQf 2100+ 1.733 188 108.5 194.0 130.0 2000+ 1.666 175 105.0 15.2 10.0 1900+ 1.600 174 108.8 14.9 10.0 1800+ 1.533 173 112.9 89.6 60.0 1700+ 1.466 167 113.9 30.3 20.0 1600+ 1.400 165 117.9 59.7 40.0 1500+ 1.333 161 120.8 n/a n/a Northwood f(GHz) score DP/Df dP/df 2.200 216 98.2 55.0 2.000 205 102.5 105.0 1.800 184 102.2 45.0 1.600 175 109.4 Willamette f(GHz) score DP/Df dP/df 2.000 183 91.5 60.0 1.900 177 93.2 70.0 1.800 170 94.4 50.0 1.700 165 97.1 50.0 1.600 160 100.0 70.0 1.500 153 102.0 60.0 1.400 147 105.0 n/a <edited> what you showed does create an impression that NW scaling is better but from what I see it is far less than conclusive ( willing to be convinced otherwise )
