Frequency Ramping
Performance in the previous era of computing was primarily about increasing the CPU clock. “Frequency ramping became the primary engine behind processor performance gains” (p. 3).
The problem was that, as the CPU clock was increased, power consumption and the heat that it generated became more and more of a problem. “Power consumption and heat generation rise exponentially with clock frequency” (p. 3).
The problem became so bad that the rate of increasing the frequency of the CPU had to stop. Clock frequency shall continue to increase. But it won’t be the rate of the past. “Frequency ramping will continue into the future, but at a much slower rate” (p. 3).
