That number isn't very meaningful - because it applies to the base clocks only... which is a big catch. Go beyond that and the power usage balloons quickly (won't repeat myself, see my other comment on this thread at https://news.ycombinator.com/item?id=25231798 https://news.ycombinator.com/item?id=25231798). On laptops, more power efficiency maps directly to increased performance (turbo clocks provide higher performance in bursts or at the expense of your laptop's fans sounding like a jet turbine).
