Reply To: MIPS/sqrt(W*$) as a better metric

We stopped using the metric due to lack of hard data and because too many people were confused by it; the concept of a design space (from which the metric came), as opposed to benchmark comparisons, turned out to be too much for many of the audience, and the resulting wrangling was pointlessly distracting.

We still don’t have better data, but have no objection to thoughtful posts on the subject, such as yours.
