I will need to clear up discrepancies between the two tables below
Below are SPEC CPU 2006 Integer base results for the Opteron 8439 2.8GHz (Istanbul), Xeon X5680 3.33GHz (Westmere), the Xeon 7560 2.26GHz (Nehalem-EX) and the IBM POWER7 4.14GHz.

The purpose of excluding lib quantum is to compare single core performance. The Intel compiler can parallelize lib quantum, so it is not a single core result(?). I am somewhat inclined to also exclude hmmr because the Intel 11.1 compiler made substantial improvement over their 11.0 compiler. AMD results are on the PGI 8.0 complier, which may not have either optimizations.

The purpose of excluding lib quantum is to compare single core performance. The Intel compiler can parallelize lib quantum, so it is not a single core result(?). I am somewhat inclined to also exclude hmmr because the Intel 11.1 compiler made substantial improvement over their 11.0 compiler. AMD results are on the PGI 8.0 complier, which may not have either optimizations. The IBM compiler can achieve spectaclar libquantum (909) in the Peak test, but not in the Base test. In the Peak test, the Xeon 5680 and POWER are very close (41.8 to 44.0)
Without libquantum, Xeon 5680 3.33GHz is still the most powerful processor. However, the IBM POWER7 is now clearly ahead of the Xeon 7560 at 2.26GHz.

Below are the SPEC CPU 2006 Integer base results for recent Xeon and Opteron processors. SPEC CPU used to be a single core metric, but new compilers generate threaded code for some of the components.
