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.
I wouldn't use specfp**** ratios as a realistic guide for performance
comparison. As always, use your own code. If your code shows 2x,
great. If not, then attribute the specfp**** to what they are
(marketing numbers, with some grounding in reality, but not a firm
comparison metric for dissimilar apps).
