As shown in Fig. 4, the innovations that enable dramatic efficiency gains in typical use are likely to encounter the same limits that slowed the gains in peak output efficiency. Typical energy usage asymptotically becomes dominated by peak output, which is still hostage to the Moore’s Law slowdown. For this reason, we’ll have to fundamentally rethink how we design computers in the next few decades, because of real physical limits to our current architectures and transistors [5]. Radically new technologies will mean different constraints and thus different rates of efficiency growth. However, in the meantime, we can enjoy the energy-efficiency gains of typical-use optimizations that have put us back on the Moore’s Law curve for at least a few more years.
