Whatever you do, don't blame the bad economy on Intel. Engineers working for the chip maker claim today's processors have netted a savings of 20 Terawatt hours over that of earlier generations if used in the same time period. In monetary terms, that equates to saving the world economy $2 billion in energy costs since the Core architecture's launch two years ago. Of course, the inefficient and hot-running Prescotts of yesteryear didn't exactly set the bar very high for green improvements, but $2 billion (if correct) is impressive no matter how you slice it.

"This is no small figure - it’s a significant amount of energy savings, and an example of what technology innovation by the ICT industry can do to improve energy efficiency on a large scale," writes Lorie Wiggle, GM of Intel's Eco-Technology Program.

Meanwhile, while Intel's Atom series doesn't have nearly the global energy impact as its desktop and business CPUs do, it's interesting to note that the recently released dual-core Atom 330 processor doubles up its power consumption over the Atom 230 processor.
