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).
