"As they article writer explained to a comment of mine, to do that would require a complete redesign of Jaguar since designing for FinFET transistors in very different to designing for planar transistors. If it was a simple node shrink they could easily keep using Jaguar (or its successor, Puma).

But going from planar to FinFET requires a redesign. And does not make sense from either a financial point of view or a technological point of view to redesign an existing CPU and GPU. It makes much more sense to use processors designed for FinFET, ie, Zen and Polaris.

This ends up not only with a much more powerful SoC, but it is cheaper to design that much more powerful SoC than to redesign the Jaguar based SoC as they can piggyback it onto already existing R&D for 14 nm FinFET. Even if AMD and Sony were in great financial situations it would make more sense to do things that way."

1) It doesn't require a complete redesign. It requires a respin and a few minor changes.

2) The cost will be insignificant, majority of the cost will be eaten up by the GPU.

3) We have no idea if it will be using 14nm Finfet. It may be manufacturered at TSMC (Like the current chips) which is 16nm Finfet. (Aka. rebranded 20nm.)

4) AMD has often historically taken older GPU/CPU designs and shrunk them down to smaller processes so they can learn about the new geometry size to improve yields.

5) For the love of God please wait on legitimate information instead of reporting on every single possible rumor please, the only rumor we haven't had is that the Power Supply is going to be powered by mice running on the inside of a wheel.

I call bullshit. The Xbox One S also is finfet and has a Jaguar CPU still.
Zen isn't even out yet, is it? Not to mention that this would mean a huge upgrade to the ps4.

This.

However, Zen has taped out and should be pretty much ready for 3rd party designs now... However the Neo chip design likely predates Zen's tapeout.

Neo would likely be using Jaguar or Puma in my opinion, it makes the most sense.

This is the post I was looking for. Thank you, Pemalite.
