The problem is that what do you measure. When you move computation from the CPU to a GPU for example does it consume less or more. I think that such analyses are totally stupid. Is a fast execution consume less? I have serious doubts about it. Now if we measure how fast we drain a battery because of polling vs event based then this is different.
