[Beowulf] Recent comparisons of 1600 MHz external Harpertown vs. 235x AMD processors?

The comparison is against Harpertown 2.8 at 1.3GHz FSB since they have
equivalent power consumption. Look for instance at compute intensive
applications.
Comparison against Harpertown 3.0 at 1.6GHz FSB with 800MHz isn't there but I
can say despite its improvement on multiple directions it does not close the
huge gap on those memory intensive applications.

performance study/benchmark of the "Harpertwon" family of Intel Xeon
processors running with an external clock of 1600 MHz against a suitable
high-end member of the AMD "Barcelona" family, e.g., 2354 or 2356?

and conducted by "consumer grade" web sites like Tom's Hardware and Anandtech.
 I'm looking for something more rigorous, and done with a mind toward
parallel/cluster applications, preferably on some form of Linux.
