2006-Q1 Intel Cedar Mill 65 nm processor Prescott-shrink, fill the gap between Prescott and Conroe. Said to be prepared for dual cores but will start off as a HyperThreading (dual threads) supporting single core chip. Newer info says that it is half a Presler. A value version with 512 KB of L2 cache, no HyperThreading and a slower bus is also rumoured.
2006-06-19 Intel Woodcrest DP server version of Conroe. Will have FBD (Fully Buffered DIMM) which is said to allow for "stupidly large amounts of RAM". Said to be planned for future Macs. Will be named 5160, 5150, 5140, 5130, 5120 and 5110.
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
