What's non-RISC about POWER?
IBM's power consumption is probably mostly because they've never put the processors into energy sensitive applications. More importantly, they are sold because of some benchmarks and extreme reliability.

Note that most ARM processors are two-issue in-order, so RISC is still relevant at the low end. Compare power consumption of ARM vs. equivalent Atom processor. Intel has a process advantage with Atom, but ARM is still lower power.
