It won't be very long anymore before AMD's six-core Istanbul server processors will become available in high volume, and you know what ? That's the start of a new multi-core race. AMD unveiled it aims to release a 12-core part in 2010 already, and a model with 16 cores in 2011.
The 6000 series processors will see the 45nm 8-core to 12-core Magny-Cours next year, while the 32nm 12- to 16-core Interlagos will arrive one year later. The 4000 series platform on the other hand will see the 45nm 4- to 6-core Lisbon in 2010, and the 32nm 6- to 8-core Valencia in 2011.
Fun fact, the new DCA 2.0 architecture will allow quad-channel memory configurations as is has a four channel integrated controller.
