You have a large inventory of Intel processors that run at 3 GHz and 1 Volt, and consume 100 W (of which, 20 W is leakage) when running a given CPU-bound application. This application finishes in 100 seconds on this processor. The processor is capable of DFS and DVFS, but cannot reduce its voltage under 0.9 V. A customer places an order for motherboards that have inexpensive cooling and power delivery that can only handle a processor that runs at 40 W.

How will you configure your Intel processor so that it meets these specifications and consumes as little energy as possible for the same CPU-bound application?

How much energy does the processor consume to finish this application on this new system?
