Nintendo NX very likely will have AMD x86 chip, possible 14/16nm

Both Zen and Excavator (the CPU inside the SoC) are x86 (more exactly they are x86-64, as they are 64bit chips like all the chips made in the last +5 years), and both Artic Islands and GCN are also common and as easy to program as you can get.

Another thing that doesn't have to do with the hardware, is if developers will be able to port PS4/X1 games to NX easily, and the answer is that it will be as easy or as hard as the publishers want (they always find new and surprising reasons to not develop for Nintendo consoles).

Well, but at least there are less technical issues, like cartridge, minidiscs, no HD (modern), or PowerPC/underpowered console.
