AMD revealed in late June that it planned to begin shipping its first “Barcelona” quad-core Opterons this month, and that its partners would start shipping Barcelona-based systems in September. If the folks at CNet have their facts straight, the Barcelona launch could very well take place on September 10. AMD has reportedly been sending out invitations for “the most anticipated premiere of 2007,” an event that will take place at the Letterman Digital Arts Premier Theater in Lucasfilm’s San Francisco campus. CNet reckons the premiere in this case will be Barcelona’s. The site also mentions that an AMD spokesman it quizzed about the nature of the event “wouldn’t explicitly confirm” whether it will be host to the new processor’s launch.
