This chart was a bad idea when RWT published it years ago, and it's still a bad idea today. It's simplistic to the point of being wrong. Peak flops/mm and Peak flops/W don't matter. Otherwise, we would have seen widespread Silverthorne adoption in HPC after RWT crowned it king last time - which never happened.
What matters is delivered performance on applications people care about. This link at least attempts to address that question. The more interesting questions of delivered performance/$ and /W are harder to get at, but are the things that really drive decisions about which architecture to use. Peak flops/mm and Peak flops/W is marchitecture - the GHz wars all over again.
