Intel’s figures show that increasing a processor’s clock speed by 20 percent provides a 13 percent performance boost but a 73 percent jump in power consumption. If clock speed is dropped by 20 percent, there will be a 49 percent reduction in power consumption but only a 15 percent drop in performance. However, although the new technology has its benefits, not least improved performance, the impact on the software industry and its customers has been disruptive in the extreme. Pricing for multicore processors is incredibly confusing.
