AMD shows off details of K8L

First, it has a shared expandable L3 cache, necessary because it is a native quad-core design. The one massive enhancement to the mix is that AMD finally has the ability to independently change core voltages for power savings. It now can also change the north bridge voltage independently of the cores. This is a huge win, we are told voltage differentials and problems with them were one of the main scaling headaches of the K8 core to this point.
