RealWorldTech wrote a lengthy article about AMD's upcoming Barcelona processors. Here's a snip:

The first information came out in a keynote address from Senior Fellow Chuck Moore at the Spring Processor Forum in 2006. At the following Fall Processor Forum, Ben Sander gave a much more detailed outline of the microarchitecture for Barcelona. More recently, Shawn Searles gave a presentation at ISSCC ‘07 which described the physical implementation challenges of Barcelona and some of the design choices.

Barcelona is the first major architectural alteration to the K8, since it debuted in 2003. The K8 built on the very capable microarchitecture of the K7, and added 64 bit operation, two integrated DDR memory controllers and 3 HyperTransport lanes. These features were not novel; AMD’s architects followed in the footsteps of the Alpha EV7, which was the first MPU to integrated memory controllers (8 channels of DRDRAM), on-die routing (4 inter processor links) and directories..
