According to SPECfp2006, the X5560 should blow the doors off of the E5430.
The X5560 scores 36 while the E5430 scores about 18.
However, our own benchmarking using nbench, unixbench, and a home-grown
utility (twobod) all show that any differences are attributed to clock speed.

Has anyone else seen this? Any ideas to explain why this is? I am thinking of
going with the 3.2 Ghz version of the Harpertown chip clocked over the Nehalem-
based 5500 series.
