How do you know? Do you work for AMD? I'm starting to get curious where you get your information. I haven't really looked into your claims that the Athlon "theoretically" performs better with better FSB because it is impossible as of the moment. No motherboard can overclock to even 166mhz FSB. 333mhz FSB is unheard of. From what I can tell, everything you have given is either speculation or theoretical. And AMD is moving past the K7 architecture (which is over 2 years old). Edited: A copy of AMD's roadmap http://images.anandtech.com/reviews/cpu/amd/athlon4/mobile/roadmap_sm.gif Notice that AMD is slowly moving the higher markets into the Hammers after Barton.
