The first launch will reportedly take place in the second quarter of next year with the introduction of a "Barcelona" core that will support the current HyperTransport 2.0 specification and work with existing motherboards and chipsets. The second launch is prepped for the fourth quarter of 2007 and will see the appearance of a "Budapest" core with support for the new HyperTransport 3.0 spec. Budapest chips will be part of the Athlon 64 and one-way Opteron 12xx lines. Finally, in the first quarter of 2008, AMD will launch a "Shanghai" core that will take HyperTransport 3.0 to the two- and four/eight-way Opteron 22xx and 82xx lines. However, The Inq says the Budapest and Shanghai launches could be pushed back because of potential availability problems with next-generation chipsets.
