Could it pass the Athlon in efficiency?

performance inprovements over previous versions of the Pentium 4
processor. Specially the shift/rotate unit has been moved from the complex
integer unit to one of the simple integer units. This means that a rotate
can be completed in half a clock cycle as opposed to the previous 4-6
clock cycles. Since RC5 depends heavily on a rotate instruction this
improvement potentially could increase the Prescotts speed. Of course a
new core needs to be developed to take advantage of this redesign.
