By that reasoning, ARM should have gone OoO years ago.
And maybe even 8 bit µCs should have gone OoO too.
(yes, I'm exaggerating!)
You're just being taken over by your dislike of dumb, fragile CPUs.
This is not a matter of just energy efficiency, though. More than that, there are power levels that must simply be met.
Give Atom's power envelope target and the node it was introduced at, it's not hard to believe a better performing x86 with OoO was unfeasible.
I don't think you'll come up with a better counter example. Look at the node and power of levels of AMD's Bobcat and ARM's A15.
