Intel's new Atom processor (code-named Silverthorne) is designed to consume only a fraction of the power of a traditional processor. The processor gets away from complex architectures and large L2 caches and closer to slimmed-down energy-saving CPUs tailored to the specific job they are intended to do. The processors are a popular choice for ultra thin, notebook computers that will be almost as fast as, but far less power-hungry, than their more conventional counterparts. Similarly, other manufacturers, aware of power waste, are promoting green systems that automatically reduce power consumption until it is needed. Is this type of energy conservation worthwhile? Is it too small a savings to worry about?
