Today is a huge day in terms of significance for AMD, who just moments ago launched the first major redesign of their processor architecture since 2003. AMD has not been able to keep the new architecture much of a secret as the new 'Bulldozer' core architecture is widely known amongst enthusiasts and gamers. Another reason that so many people know about Bulldozer-based CPUs is because AMD already announced Valencia and Interlagos processors for the server market. Today is significant in the sense that AMD is launching the  first new Bulldozer-based desktop CPUs that are codenamed Zambezi and feature up to eight cores.
