What do yo think will be the hardware specifications of PS5 if it arrives arround 2019-2020?

You should compare original ps4 to ps4 pro. You see a 1,8 TF jump to 4,2 TF, overall 2,3x increase. And this gave a higher power consumption when comparing the two consoles. Expect something similiar with Ps5 if they launch 2019-2020 with 7nm transistor technology. About 9 TF is my guess.

If they go for a higher TF number, they either has to increase the chip size or go with higher clock speed. Which just lead to higher cost for a bigger chip and more expensive cooling.

Why though? we could just as easily compare the OG PS4 to the XB1X. Afterall we are locking at the same architecture but with 40CUs(4 deactivated) on the PS4pro and 44CUs(4 deactivated) on the XB1x. The XB1X GPU is just running at a much higher clock.

I dont see how you can say all you have said and just ignore that the XB1X exists. Forget the cost saving shenanigans in the PS4pro. The XB1X represents whats possible. Look at it this way, using the exact same chip size in the XB1X but at a 7nm node will give you 88CUs, where if clocked identically would give you at least 12TF. And this is assuming its the exact same architecture. 

But it won't be, so those 88CUs will perform better and be more efficient, clock speeds will go up by at least 10-20%.... all that is already putting you in 14/15TF territory right there. 

Considering how easy it would be for them to hit 12-15TF GPU and have that for the next 6-8yrs you really think they will puss out on that and settle for 9-10TF? When they know they have competition in the Xbox? Not a chance.

I'm not ignoring xbox one x. Xbox one x proves my point. Microsoft had to go with a bigger chip and more expensive cooling to get those extra Flops. So if we assume 7nm will be able to double the Flops with same power consumption we will get 12 TF. But this require a bigger chip and more expensive cooling.

How much improvement we will get from 7nm compared to 16nm we don't know exactly. TSMC (The chip manufacturer) has said 7nm brings about 60% power savings. But this is probably a bit optimistic.

And I don't expect sony to go that route microsoft went with xbox one x. They wanna keep the power consumption at the same level and keep cost down.

About Amd next architecture Navi, I'm not expecting much at all. Polaris was bad, Vega was a disaster and we already hearing Navi will be worst than Vega so don't expect much from Navi.
