Performance per What?

Akenine-Möller, Tomas LU and Johnsson, Björn M LU (2012) In Journal of Computer Graphics Techniques 1(1). p.37-41
Abstract
In this short note, we argue that performance per watt, which is often cited in the graphics hardware industry, is not a particularly useful unit for power efficiency in scientific and engineering discussions. We argue that joules per task and watts are more reasonable units. We show a concrete example where nanojoules per pixel is much more intuitive, easier to compute aggregate statistics from, and easier to reason about.
