amd athlon difference

does anyone know what the deal is with the new thoroughbred processors? are there any good or bad differences between them and the original athlon xp(palomino) processors?

the main difference is the .13 micron manufacturing process as oposed to 15 on palomino. Second the FSB went from 133 to 166 double pumped of couse so the troughroubred has a FSB of 333.
Third it has a few new intruction sets.

also the newest (barton core) is a troughroubred with 512 cache.
