Tukwila, which has been on Intel's roadmaps for quite some time, has eight plus one spare core, which are connected by two counter rotating rings, making it the first links based member of the IA-64 family.
Internally, Intel calls this the common system interface (CSI), but it doesn't come from the ex-Compaq/DEC people that designed the Alpha EV7. It's been designed by the same people that were working on the EV8, the Alpha generation thatt never taped out.
As for Whitefield, this is a plan of action for a four core IA-32 system, although it appears it hasn't yet been decided which core it will use. Tanglewood is not quite dead as a dodo. The sources claim that that it will use the system interface designed for this duck of a processor.
We do hope that Intel is still pouring money into its Israeli R&D center, because from what we're hearing, shorter pipelines make for finer chips, and the guys and girls over there sure know what they're doing on that front. µ
