Will the NX be Powerfull?

Not exactly.

AMD's successor to the consoles archaic and slow Jaguar CPU's, aka. Puma... Can operate at powerlevels of 3.8w with 128 GCN cores and 4x x86 1.6ghz cores.
At 16/14nm, you could halve that power again or double the hardware.

Intel has had mobile SoC's that have been able to beat out it's ARM competitors in many cases for years.

As for Price, you have a point.

Lol im not an hardware expert but i highly doubt you could achieve ps4 performance (graphics and cpu whise) with 3,8 wattage. 

It would be amazing if possible, but i really cant believe it.

CPU wise it can be done with ease.
Jaguar is old and slow, it wasn't much of a CPU to begin with anyway, CPU's don't make games look super pretty which is used in advertising to sell better looking games.

Might be doable when we hit 7nm, having a PS4-level SoC at 4~ watts.
At 14/16nm we are seeing gains of 2.5X in energy efficiency, it won't happen though unless a company wants it custom made to order, the PC though will be getting a 200-300w APU with HBM tech which should run circles around the PS4 this year with some luck.

We also have Tegra's K1 GPU which can do 350-400Gflop at 28nm and consume 2w of energy~ for the whole SoC, imagine that with 2.5x the efficiency? And again another 2x at 7nm? That's more performance than a PS3 despite only using about 2w and it's built at 28nm.

The big issue though would be RAM. Amount and Bandwidth rather than the CPU and GPU, you can't have high bandwidth and low power consumption, mobile tends to work around this with tiled based approaches and LPDDR3/4 rather than hungry GDDR5.

Plus on a mobile device you can get away with games running at a lower resolution and using scalers to pick up some of the slack.
