According to Kazushige Goto, these are the peak performance numbers he
obtained with Linpack and GotoBLAS, with tuning for Nehalem not yet
completed.
AMD Opteron "Shangai" 6MB L3 : 90% of peak
Intel "Nehalem" Core i7 : 95.2% of peak
Intel Itanium 2 : 95.6% of peak
It's a Core i7 but should give you an idea.
Best regards,
Tiago Marques
