Intel performance with loops vs. vectors -

Has anyone done any direct comparison of performance of modern Intel or AMD
processors running floating point operations as both vector operations and
as simple loops?  Does it make a difference any more?  Some of the results
posted to this list seem to imply that loop calculations now run as fast as
vector op.s on today's microprocessors.  We are considering some tests but
would appreciate any insight or comment people would be willing to provide.

W/Thanks & Regards/ Dave Lechner.
