Intel Details Nehalem uArch Improvements - 256KB L2, 8MB L3 Confirmed

the MCH itself dont draw much power, 5-10W perhaps in the enthutiast and less in the normal. The main powersucker in a NB is the PCIe controller.

I think P965 as an example had a 21W TDP but used around 8-9W with actual usage and on 90nm. This is 45nm.

To say 30-60W is just clueless fearmongering.
