Crazy Harry schrijft dat ze bij The Register een interresant tabelletje hebben, daarin staat dat een dual Pentium III sneller is dan twee keer de snelheid van een single Pentium III.
Amid the horror of Caminogate and Rambus, an increasing number of observers are singing the praises of Chipzilla's earlier chipsets, the desktop BX and the server GX. They may not be state of the art, but they have a major benefit: they work. In the case of the GX, they appear to work better than conventional wisdom would allow.
Intel's Lancewood server mobo is a dual slot 1 device with all the usual server gubbins thrown in - LAN, graphics, etc. Having two CPUs is usually reckoned to give between 1.5 and 1.75 times the performance of a single processor.
Why is it then that our reference PIII 500 machine, using a Sun River SR440BX, returns a Wintune 98 integer score of 1453.077 Mips and the Lancewood reports 2916.869 Mips rather than a best case scenario of two times the uniprocessor score? Both machines have 128MB of RAM, all three PIII 500s are the same stepping and have identical 6GB hard disks, so where do the extra Mips come from?

En ik altijd maar denken dat een de tweede CPU in een systeem geen performance winst van 100% zou opleveren, laat staan meer dan 100%...
