In Intel parlance, core names correspond to a given process (130nm, 90nm,
etc.) so there is no such thing as a 130nm Prescott, only 90nm Prescott.
P4 Extreme Edition is a derivative of Northwood called Gallatin, it has the
same relatively efficient 20-stage pipeline (rather than the 31-stage pipeline
of Prescott), with an additional L3 cache, still on a 130nm process.
Wikipedia has an ok chart:
> idle curiosity, since none are in s478 pkg - what's the 65nm name?
I think you're asking "what is the name of the 65nm family of Pentium 4
processors for LGA 775 sockets?", right? That would be Cedar Mill.
