The gigahertz race is over. For over two decades, microprocessors have been doubling in clock speed and performance every one or two years. In the past two years, this exponential trend has been replaced by a slow climb. Heat is the culprit -- the technological trends that drove CPUs up in speed also drove them up in power consumption. Heat limits the CPU and graphics processor in a desktop computer; power limits the battery life of laptop computers, PDAs, and cell phones; and large computing companies such as Google and e-bay are limited airconditioning for their warehouses full of computers. Parallelism is the most promising solution. The physics of the transistors that make the chips work mean that if a task can be divided between multiple CPUs, the total energy can be much less than if the task were done on a single CPU. This is why every computer manufacturer is coming out with multi-core processors.

千兆赫竞赛结束了。 二十多年来，微处理器的时钟速度和性能每隔一两年就会翻一番。 过去两年，这种指数趋势已被缓慢攀升所取代。 热量是罪魁祸首——提高 CPU 速度的技术趋势也提高了它们的功耗。 热量限制了台式计算机中的CPU和图形处理器；电源限制了笔记本电脑、PDA 和手机的电池寿命；谷歌和 e-bay 等大型计算公司为其装满计算机的仓库配备的空调也很有限。 并行性是最有前途的解决方案。 使芯片工作的晶体管的物理特性意味着，如果一项任务可以在多个 CPU 之间分配，那么总能量可能比在单个 CPU 上完成该任务要少得多。 这就是为什么每个计算机制造商都推出多核处理器。
