I don't know the answer to that.  I've never seen a dual and single cpu machine
get the
same NPS if the processors are the same speed.  The dual should be near to 2x
faster with
respect to raw nodes-per-second, and somewhere in the range 1.5-2.0 times faster
in terms
of time needed to get to a specific search depth.
