I think the notion that Scorpio has to be expensive to have those kind of specs is a pretty silly one, given the price of AMD's latest GPU tech and the fact that it can be significantly over clocked and also that refinements to that tech will be made for 2017 cards.
RX 480 at retail is only $199, that's not what Nintendo or anyone else building a console will pay for it and that includes 4GBs of pretty fast memory, it's been said that this GPU can be clocked over 1500MHz, which makes it possible to hit 6.9TFlops, in a 2016 GPU releasing very soon, that's very cheap.
If something with the specs of that card can produce that level of performance then a cheaper chip, with fewer compute units could certainly hit 6TFlops if it was clocked fast enough.
Another point to make is that Nintendo would likely be using AMD or some other vendor, who does the work of making the processor for them, they go to a host of other vendors of tech to provide them with what they need, they aren't designing processing tech themselves or everything within this system to then piece it together themselves, they don't even handle the manufacturing of the final console themselves, because all games console designers within the big 3 dedicated console market place uses foxconn.
Tech to make a powerful machine is cheap, will only get cheaper by the time NX launches.
I find it laughable that anyone thinks even Scorpio will have to be anymore expensive than the $399 launch price of the PS4 back in 2013, when it releases in late 2017.
I don't think NX will be anywhere near that level of performance, but mainly because Nintendo seems to like their systems to be very low on power consumption, if NX was using the latest AMD GPU tech and some variation of a modern mobile AMD CPU then they could certainly end up with something a good 80% faster than PS4 or even double the performance of that system.
If PS4 can handle games like Horizon at 1080p 30FPS, then Nintendo would be mad not to try and make a modern console with the ability to run that level of gameplay and visuals at 1080p 60FPS.
If CD Projekt Red are commenting on it, then I think that hints that it's likely using X86 and something prett reasonable for modern gaming.
Eurogamer had eluded to Nintendo going to 3rd party devs to ask for their input on what they wanted in the next console when development for NX began, back in 2015.
I think the whole notion of an Arm based console or Nintendo going to another vendor besides AMD was a stupid one when they've been great partners for ages.
Hopefully Nintendo doesn't wait too long before unveiling and put to bed the ideas that make zero sense.
