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

Not a study, but recent published comparisons on an OpenMP application
benchmark suite, SPEC OMP2001 are available:

AMD Barcelona,  Opteron 2356, dual-socket, 2.3 GHz:
http://www.spec.org/omp/results/res2008q2/omp2001-20080325-00291.html 
SPECompMbase2001 = 17598

Intel Harpertown, Intel Xeon E5440, dual-socket, 2.83 GHz:
http://www.spec.org/omp/results/res2008q2/omp2001-20080325-00292.html
SPECompMbase2001 = 14789

Both these results were run by AMD, but they used an Intel-produced
config file on the Intel-CPU-system runs.
Note that AMD did not use the fastest Harpertown CPUs available, but
they are pretty decent speed -- I seem to recall that AMD had a
rationale of choosing similarly power-consuming CPUs, but I could be
wrong there.  The SPEC HPG committee, which includes Intel, reviewed the
results to see that they followed the run rules before accepting them
for publication.

Different compilers were used, but they seem like logical choices for
the CPUs involved: PathScale for Barcelona, and Intel for Harpertown.
