AMD this week confirmed plans to introduce a quad-core server processor by 2007. The design will gradually be extended to desktops and notebooks. During Tuesday’s analyst conference, AMD CTO Phil Hester explained that the cores will be linked by a revised type of HyperTransport bus and will use the M2 and F sockets expected to arrive early next year. Rival Intel plans to introduce a quad-core Xeon in the first half of 2007.
