BAD HARDWARE WEEK

At the Intel Developer Forum, various executives spun the yarn about Intel taking power consumption issues seriously years ago. In addition, the company long had an ambitious multi-core processor plan in place, we were told. Now Intel will combine the fruits of all this work to crush the competition on a performance per watt basis.
(The claims about such a masterful plan are comical when Intel admits that surprise development work in Israel has led to its entire future line of chips.)

Intel's attempt to put a stranglehold on the performance per watt dialogue currently dominating the chip industry will amuse many.

Currently, customers have to watch as about 52 per cent of their power evaporates between the wall socket and the actual machine. By 2010, Intel expects major improvements in power delivery to the point where 85 per cent of the energy gets to the box.

Bad hardware comment: VRM 11 specification for Conroe offers VRM power efficiency of some 80 - 83%. PSU efficiency depends of its type you use, but generally is close to VRM's efficiency. And finally, Intel will show how Conroe itself is power efficient at max performance. We eagerly wait.
