Most of the benchmarks consider speed, some consider speed/Watt, but
none I have seen consider speed/monetary cost. The reason is partly that
the component cost is a highly variable parameter and not always easy to
But while configuring a cluster remember that you can get a better
deal (=speed/cost for your application) by choosing cheaper CPUs in
