this was 10k's no filter updated quote from the dev, which he is still leaning on despite being a lone source:

"So far I know this: Polaris architecture as a base, mixed with Fiji, low power consumption, raw power numbers are modest increase, performance for optimized games for NX would be easily 2x PS4 performance."

If you look at r9 nano (Fiji XT), it has a core config of 4096:256:64 = 8.192 TF @ 175w.

For the tech heads here, is it possible Nintendo could get a custom gpu based of that card, lets say Nintendo wants 1/4 of that so 1024:64:16, how much could that possibly drop the tdp, on either 14 or 28nm?

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.

 

Edit: for further references, this wikipedia page is very useful: https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units

Not only details each AMD GPU, but it also says what's what. For example, the R7 370 and 1024:64:32

1024 = nº of shaders (the ones that do the calculus)

64 = nº of texture units (the ones that decide which and where do textures go)

32 = nº of ROPs (the ones that transform the info of the GPU into the images we see)
