MacDork's Journal: Power to cost more than hardware?

C/Net is reporting that Apple isn't the only company concerned about performance per watt. Google engineer Luiz Andre Barroso is quoted as saying "If performance per watt is to remain constant over the next few years, power costs could easily overtake hardware costs, possibly by a large margin." CMP (chip multiprocessing technology) is hailed as a stopgap rather than a panacea. According to Barroso, "Fundamental circuit and architectural innovations are still needed to address the longer-term trends."
