If you read:
http://www.intel.com/design/itanium2/download/14_4_slides_r31_nsn.htm

and go to pag.24, you will note that Intel
don't have problem to lower power below 1.6-1.5Ghz.

If necessary, a 1.3Ghz 6MB model go at 1.1V and
likely even less with half L3.........

Yes but this is true? Or Intel will make a single core
0.09u cpu in the second half of 2004 and a double core
Montecito in 2005 ;)????
