I think that today it's not that much about power and efficiency. It's about production costs. Nintendo is using an extremely custom chip, one that probably cost them quite a bit in R&D, and is costing them quite a bit to manufacture because most probably they're the only ones producing it and buying it... Only to keep hardware backwards compatibility. A backwards compatibility that is pretty easy to achieve via software on x86 and x64 PC's.
Certainly not the point of your topic, but eh.
