Although the folks now using CUDA are likely most interested in crunch per unit time (time efficiency), perhaps some of you have measurements and can comment on the energy efficiency of GPU vs. CPU computing? That is, which uses the fewest kilowatts per unit of computation. My guess is that the most energy efficient solution is still CPU based, because Intel and AMD have both worked hard on that issue. Seems like this sort of information would be useful when comparing CPU and GPU based solutions, in order to determine the overall cost efficiency (total crunch /(purchase price + operating expense).
