It is not clear if AMD 65nm designs will leakier, or Intel 65nm designs. AMD's p-channel gates leak less current, but AMD n-channel devices have much higher OFF state current. The contribution of each component to the quiescent power is a function of the details of the circuit design. However there is no question that the HiK dielectric will reduce both leakage currents by an order of magnitude. Not surprisingly this has translated into dramatically lower power dissipation numbers on the Penryn. So until AMD can put its HiK dielectric gates into production, Intel will be King on the Quiescent Power Dissipation issue.
