I suspect many are waiting for the new socket F opterons, which are
supposed to reduce power consumption as well, before doing comparisons.

The new xeon does use less power than the old one, and runs faster.  It
still has the same bottleneck to deal with in multi cpu systems of
course, that the opteron doesn't have.  Of course the opteron also comes
in HE (high efficiency) versions which reduces power consumption quite a
bit.  They are often used in blade servers for that reason.
