It began as a follow-up to our article Turion 64 on the Desktop, posted in mid-February. But then, the piece ballooned into something more ambitious, into an attempt to answer the question,
"What is the best power efficiency achievable with currently available AMD and Intel processors that can be used on a desktop PC?"
In the process, we examined more than 15 processors from half a dozen family groups on six different test platforms, and took a stream of power measurements that kept our heads spinning for a couple of weeks. We have some answers. They comprise a snapshot of the fast-changing processor scene, taken from a particular angle, at this particular point in time.
