AMD reveals Barcelona performance, future plans
 

Once Barcelona finally rolls out, AMD has no intention of twiddling its thumbs. That sentiment was exemplified by a roadmap the company showed depicting its server and workstation core launches for the next year and a half. Those upcoming cores will include Budapest, which will power future quad-core Socket AM2 Opterons, as well as Shanghai, Barcelona's 45nm offspring. Budapest isn't too exciting (think a server/workstation variant of Phenom) but Shanghai definitely is. The chip should be AMD's first 45nm endeavor, and it's still scheduled for mid-2008. Compared to Barcelona, it will pack 6MB of L3 cache and 'continued [instruction per clock] improvements,' but it will fit into the same Socket F motherboards as existing dual-core Opterons.
