"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."

hmmmm.... interesting.

I'm reading conflicting information. 

I thought the XB1s is built using 16nm finfet. If they can do that to the XB1 APU then they can do it to the PS4 APU.

So I believe the PS4s/XB1s are using 16nm finfet. 

But Polaris and Zen are on 14nm finfet?

What's going on here?

Permalite where are you when we need you??????

Well,we will al know the answer next week.
My money stands ready at least if its not 500.

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.

100% sure is not going to use a zen architecture.

Doubt it but hey! We shall see in a week

Would make the console significantly more expensive most likely, since the jaguar is a very very low end CPU and the ZEN is not.

But lets just wait,m 7 sept is around the corner.

First, DF reports about PS4K dev kits being in the wild and featuring jaguar, but also reports that Sony has yet to lock down its decision on CPU

Second, E3 and MS surprise announcement of Scorpio, and Sony mysteriously lopping off part of there presentation, which most expected to be the Neo reveal

Guess, we'll know soon enough

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.

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.

I call bullshit too!

Zen microarchitecture would need to at least pass verification and debugging.
