For Crafty, Opteron is faster. For some other integer programs (including some
in Spec2k suite) Itanium2 is faster.

Overall, 2.2GHz Opteron has Spec2k peak integer score of 1477. 1.5GHz Itanium2
has Spec2k peak integer score of 1404, i.e. 5% worse.

For SpecFP situation is different -- Itanium2 is 30% better.
