AMD revealed its Bulldozer architecture should scale to 20 cores with the "Terramar" server processor in 2012:
According to AMD officials, the server version of Bulldozer is slated for introduction in the second half of 2011, which means the server part should show up before the end of next year.
The server codename for 2P and 4P enterprise mainstream platform is Interlagos and this Bulldozer based CPU has 8/12 or 16 cores depending on the SKU. It also comes with 4x HT-3 (6.4GT support) as well as quad DDR3 channel support.
The future, or should we say 2012 brings a new codename to the game. Terramar is a next generation CPU based on as many as 20 Bulldozer cores. Sitges-Terramar was the home of Spanish Barcelona (Circuit de Catalonia) F1 track.
