AMD announced back in late June that systems based on its quad-core Opterons, code-named "Barcelona," would start to ship this month. Many rumors arose regarding a specific launch date for Barcelona, but AMD stayed relatively tight-lipped. However, the company has now quelled the speculation by revealing that the Barcelona launch will take place on September 10 at 6:30 P.M. PST (9:30 P.M. EST). AMD intends to do a live web cast of the launch event, which will be accessible from this page.
As AMD stated in its analyst day presentation in July, Barcelona will launch at speeds of up to 2GHz for standard models and 1.9GHz for low-power variants. Those clock speeds may seem low, but AMD estimates that launch chips will take care of 94% of the market. Barcelona processors clocked at 2.3GHz and above will follow in the fourth quarter, as will AMD's Phenom X4 desktop quad-core chips.
