I haven' compared the Xeons recently, but we did similar tests when the
Athlons were upgraded to more cache a couple of years ago.
In general, more cache helps 10-15% extra at the same frequency for
large systems (100,000 atoms), but the difference is almost negligible
(couple of %) e.g. for a protein in water.
