2008 Intel Nehalem
Nehalem was a new design built using a 65 nm process with half the die size of a Northwood. Was supposed to use a 1200 MHz (or a 4 GHz bus as some rumours claim) bus and start at 9.60 GHz before continuing to 10 GHz+.
Nehalem is now changed to be the name of the family succeeding Merom, Conroe and Woodcrest, which is 45nm and will include Whitefield, Gainstown and Bloomfield. The Nehalem platform will use the Tylersburg chipset
2008-03-08 Intel Atom Mobile chip built in the 45 nm process. TDP only 0.6 - 2.6 , and can dip as low as 0.01W. Previously called Silverthorne. Single core draws 4W, while a dual core draws 8W.
