re: That's not bad, but it might be because AMD tends to backrev their processes with future enhancements, so their current 90nm may be very close to 65nm already. If that's the case, they won't get a significant perf/watt boost until late next year or early 2008, when they start incorporating 45nm features in their 65nm process. It's also unclear how much extra power those additional FPUs will cost them in the K8L core. It might end up that with the added transistor budget, the 65nm shrink doesn't buy them all that much.

Hans de Vries claims that AMD started the 90nm node at 100nm and only gradually shrunk to 90nm. Also at 65nm AMD will add next gen strain (SiGe added to current DSL). This alone will help the perf/watt increase about 15%.
