DailyTech has some coverage of the AMD Spring Forum, with more details about the next-generation K8L processor from AMD:
Chuck Moore, a senior AMD Fellow, gave a presentation at AMD's Spring Forum revealing some of K8L's features. Aside from being a quad-core-friendly architecture, there are three key features that will separate K8L from K8: cache, memory and HyperTransport.
Moore revealed that K8L will be the first AMD processor to have L3 cache since the K6 CPU. Each core has an independent L2 cache, but the entire processor shares an L3 cache pool. There's no word yet on exactly how much cache the K8L can hold, though the K8L will be a 65nm SOI process so AMD engineers have a bit more die real estate to play around with.
