AMD presented a 4 socket, 48-core Magny-Cours system at the Hot Chips conference in Palo Alto and revealed more information about this upcoming server processor. More info about the Magny-Cours chip can be found over here.
Magny Cours holds symbolism in being one of the last processor designs by AMD before it moves over to "Bulldozer", the next processor design by AMD built from ground-up. Its release will provide competition to Intel's multi-core processors available at that point.
AMD's Pat Conway at the IEEE Hot Chips 21 conference presented the Magny-Cours design that include several key design changes that boost parallelism and efficiency in a high-density computing environment. Key features include: Move to socket G34 (from socket-F), 12-cores, use of a multi-chip module (MCM) package to house two 6-core dies (nodes), quad-channel DDR3 memory interface, and HyperTransport 3 6.4 GT/s with redesigned multi-node topologies. Let's put some of these under the watch-glass.
