SONY can learn from Xbox One X technique on TDP optimization by soldering the APU close to the PSU.

...Umm. What.

Watch digital foundry on how Xbox solution by optimizing their TDP by soldering their APU close to the power source

You might be right, but you also need to remember we are talking about AMD GPU here, not Nvidia , 15 teraflop Nvidia will be equal to 20 to 22 teraflop on AMD gpu , and also if PS5 releasing in 2020 or even 2021 , 20 teraflop + will be a mainstream GPU or standard even on PC. And high end will be like 24 to 30 teraflop on AMD PC GPU.

Flops are flops. They are absolutely identical regardless if it is nVidia or AMD.
The issue is... The flops that gets thrown around casually like you have done so is merely a theoretical, unachievable number in the real world.

Agree flop are flop but Nvidia and AMD are different , most AMD GPU tend to have bigger TF then Nvidia but Nvidia is more efficient, so if we want to compare the TF between Nvidia and AMD GPU then we use that rule of thiumb, for example GTX 1070 6,5 TF are comparable to RX Vega 56 9 TF on Vega 56.

if Xbox One X can have 12 GB GDDR5  on this gen why not go nuts on next gen. Also future PC GPU will also go nuts. Even AMD has GPU that support 64 GB HBM2. And also even if it's imposible "a man can dream " . XD 

The Xbox One X is a "Premium" high-costing device.

The wider memory bus? Costs more.

It's cost more but it will be tackled by next gen memory that will have wider memory bus (GDDR6)

 
The extra memory chips? Costs more.

Yes , every chip cost more, but then is a nutural for every generation they added more RAM

The extra layers on the PCB? Costs more.

Again agree, but it's a natural law, more chip more cost but it will benefit more

The more complex crossbar memory controller? Costs more.

Again agree
The superior power delivery? Costs more.

Agree, but then again by time it will be cheaper 

The superior cooling mechanism? Costs more.

Agree, but better performance, higher clock  and life expectation 

And it has the price to match... Which is why it will never hit the low price points of the Xbox One S.

That's why i am expecting price around 500 USD to 550 USD  which is fine, (Xbox One X sold alot whit this price)

For a next-gen console that isn't targeting a lower price point, then you bet'cha an odd 12GB/24GB set-up will simply be unfeasible from a cost perspective. (Plus ignoring the insane pricing for DRAM right now.)

why would SONY will be using the same price method if Xbox One X can be popular in 500 USD price range, is and also SONY can just close their marginal profit for one year , until each of component becoming cheaper.

And guess what Navi is? Graphics Core Next 6.0.

Most article point out that Navi will start a transition to a new architecture, but i am sure they will have some similarities from old architecture 

They are all part of the same overarching architecture, with small enhancements at every evolutionary iteration.

Yes, but  it will be slightly different or most article point out that it will start to differ from previous gen architecture 

So yes, in short, Navi is a "revision" of the RX 500 series and by extension a revision of the same GPU that is found in the Playstation 4.

Probably, but with newer architecture , again read the interview on the article it will be different albeit will have some similarities.

Yeah , i understand cost is the problem here, but PS4 also first came with 8 GB GDDR5 when most  of High end PC GPU are 6 to 4 GB GDDR5 in 2013. And still they are managed to make a a high margin profit each of consoles sales. 

The Playstation 4 took advantage of higher density memory modules for a similar cost.
Otherwise they would have had to double the amount of memory chips and costs would have blown out

Agree, that's why PS5 will follow the same route

12GB or 24GB... I just don't see happening from a cost point of view, you would need a 384-bit memory bus to power that.

then they increase it to 384 if it need to
