AMD's 65nm Brisbane Core Previewed: The most energy efficient AMD CPU to date

@ 2006/12/18
When Intel launched its Core 2 line of processors we saw AMD's performance and power advantages vanish into thin air but the comparison, at least on the power side, wasn't totally fair. Intel had been shipping desktop processors on its 65nm process for months prior to the launch of Core 2, while AMD's Athlon 64 X2s were still built on a 90nm process. We had no way of telling how much of Intel's power advantage was due to a more efficient architecture or simply smaller, cooler running transistors. Up to now, AMD has been penalized twice in all Core 2 vs. Athlon 64 X2 comparisons; AMD's new micro-architecture won't debut until next year and neither will 65nm in any great quantities.
