Ali,

However, the main point was to find out how
much of headroom has left in the current Intel technology,
and the way to measure it must be straightforward -
under the nominal operating conditions

Isn't Intel's operating voltage on any given technology typically lower (by 0.1-0.2 Volts) than AMD's? If so, Intel has made the decision to trade-off lower operating power for higher leakage current. Their transistor channels must be less depleted when off, so that they can be effectively inverted under a lower Vcc when turned on. I am assuming that the majority of the leakage current with Intel transistors is channel leakage, and not the junction (to bulk) leakage that can be limited using SOI -- given Intel's stance on SOI.

Pravin.
