"Vastly redone architecture"? No my friend, AMD has said itself; K8L is evolutionary, not revolutionary. The changes it brings won't be enough to close the performance gap that exists between the Conroe and A64.
Cedjunior, nice work, exactly what I was thinking. Since even K8L can't bring enough architecture changes to make up the performance, Intel's Dual Cores will still be better. Plus, Intel's Dual Cores come out in Q1 2007, while AMD's K8 (yes, K8) Quad Core doesn't come out until Q4 2007. K8L Quad Cores aren't avaliable until 2008.
And all that still gives Intel time to tweak Conroe to make it even better.
