[Beowulf] scaling SPECint_base2000 for harpertown

I recently got SPECint_base2000 figures from intel for harpertown
using low optimisation flags (-O2 -pthread -fPIC). This benchmark is
commonly used in particle physics circles to provide a common base.
I was expecting the numbers to scale pretty much exactly but if you
look at the link below the faster the chip the more SPECint_base2000
you get per GHz.
Is this expected? These are aggregate figures for a dual socket
machine with 1.5GB ram per core.
