CISC is rapidly becoming a requirement, however. Power requirements scale as the square of the frequency, and also, perhaps even more importantly, leakage power, and hence, heat generated per unit area, increases as the process size decreases. As such, as process sizes shrink, less and less actual area of the chip can be active at any one time. ("Dark silicon"). In other words, you might as well have areas of the chip that aren't used most of the time, because most of the chip can't be active at once anyways.
