I don't think you can really call a sane OoOE implementation "heroic" and "burning lots of power" any more. That may have been true around P4 era when they apparently tried to make frequency and fill execution units at all costs without thinking much about power or MLP (cache misses were very much a second class citizen in Netburst). Nowadays you have very tiny and efficient OOOE cores, as well as large and incredibly powerful and still quite efficient cores (Westmere/POWER7).
