Besides gamers, who cares if it takes a few more milliseconds to launch a web browser or process an image?
I do... because that's a few less milliseconds my CPU isn't idle, which reduces battery life.
Seriously, does anyone understand this benchmark? I see pairs of performance and battery life numbers which seem to have no real-world meaning, so it's not at all clear to me why it makes sense to compare them. In addition, it's common that for a given set of tasks, a device with better performance will use less power because it spends more time in an idle state. The notion that devices trade off performance against battery life makes little sense in the ARM world.
Maybe this actually does say something useful, but if so I'm too dense to see it.
