I think willamette and northwood are basically the same wrt shifters (and pretty much everything else too, for that matter). I think northwood is a shrink, and had an increased cache size (and higher frequencies). But I think core-wise, they're very similar.

It was prescott that changed a lot (mostly for the worse - the shifter was one of the few upsides of prescott, although increased frequency often made up for the downsides).
