I'm not exactly a tech head, but I'll answer you.

AMD doesn't have a GPU with that configuration, 1024:64:16, but it has something very similar in the GPU inside the R7 370 with a config of 1024:64:32. That sounds better, right? Well, no it doesn't.

It turns out that that GPU is worse than the one inside the PS4, that has a config of 1152:72:32.

To have 2x specs of the PS4, the NX would need something like the R9 380X which is 2048:128:32, but the reality is that that only works on paper. Here is a comparison between the R7 370 and the R9 380X to show you what I mean: http://www.anandtech.com/bench/product/1590?vs=1592

To have twice the performance of a PS4 you would need something like the R9 390X, and that's too expensive and uses too much power for a console.

I definitely don't think its 2x PS4, that talk got out of hand when 14nm got mentioned.  I bring up Fiji as that's the updated quote.  For performance, the r9 nano's 8.192 tf @ 175w seems to be the best at 28nm.  I was wondering if Nintendo could get a cut down/customized version, and if the TDP would drop accordingly (by half or more?).  i.e. how much can TDP be reduced from 175w, with a lower core config that compares more/less or between XB1 - PS4.

edit @JEMC

I do look at that comparison chart, and compared Fiji Pro to Fiji XT.

I don't know how much a 14nm Fiji chip would consume as not every part of a GPU chips scales the same way to new nodes. I can't give you an answer. Half the power? Yes, it could probably be something like that. But there's something else, Nano uses binned chips. They are not the usual Fiji chips but specifically selected chips that perform better than the average ones.

Fury X uses the same chip with only a very modest bump from 1,000 to 1,050MHz and yet uses 100W more.

Now, I would forget about a Fiji based NX because of these two main reasons:

1-Due to size limits, Fiji only has 64ROPs. That limits the performance of the card at lower resolutions like 1080p because there are not enough ROPs to process all the info they recieve into frames. That's why Fiji based cards don't suffer as much as Nvidia cards when going from 1080p to 1440p or 4K.

2-They are designed around HBM, and that limits the max RAM to only 4GB. Nintendo can't launch a card with that amount of RAM and expect third party ports.

Also, it's very unlikely that NX is build with 14nm. It's too recent and the production is not high enough. If it were for a 2017 launch then maybe, but for 2016 it's highly unlikely.
