POWER is about as far from a good fit for most ARM applications as you can possibly get.

It's all about shoving a ton of hot power hungry multithread cores as close together as you can and running them at full bore.

The Freescale/NXP 4xx/75x PowerPC cores are fairly common embedded CPUs. These days POWER and PowerPC are the same ISA.

No. POWER and PPC are decidedly not the same. the closest they ever came together was the G5's 970.

4xx and 75x were OK for embedded a decade ago, but today they're hot and power hungry. You can use them in devices where you can burn 10+ watts to maintain backwards compact with existing PPC code, but they're way the fuck too hot for a phone.

POWER already has a place next to arm https://en.wikipedia.org/wiki/QorIQ.

POWER and Power (formerly PowerPC) are similar but quite different. PPC has been in embedded (but generally not mobile) for quite a long time, but even then, the cores are still hot, power hungry, and poorly suited for mobile.
