just wondering 1 thing : how come the Duron (morgan) tops out at about 1.4GHz while the AthlonXP (Palomino) tops out at 1.8 ? Aren't both built on .18 micron ? then could someone explain why there's such a difference ? I mean, aren't they both built on the same core just with different names and cache ? Why would one clock lower than the other ?
