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

They will go with whatever is cheapest. - Even the Xbox One X isn't using the biggest, fastest mechanical disks and that was a "premium" console.

SSD's/m.2 drives still command a premium and will do so even in a few years from now.
Plus the demand for NAND is increasing, so costs could actually increase, especially if NAND fabs retool to start taking advantage of higher DRAM prices.

Turns out price plummeted thanks to the abundance of stacked TLC and QLC NAND rushing onto the market, making it a viable option.
Supply/Demand in commodity markets can be a fickle thing at times!
Happy that we aren't going to be using mechanical disks, but my trepidation on the use of NAND was for naught.

Could still be interesting how Microsoft and Sony handle expanded storage though.

DDR5 isn't going to happen. JEDEC has only just finished demonstrating the DRAM and hasn't even finished ratifying the standard... And is thus probably still a few years away from a market release.
It does promise to double the bandwidth and density of DDR4, which means it's not going to be enough for next gen anyway unless you implement a stupidly wide bus.

It will be GDDR6, it will be what will offer the greatest benefits, higher capacities and good enough bandwidth/latency.
GDDR6 is currently ramping up production right now, so costs will be leveled out by the time 2020 hits.
 

Turns out I was right.

It will use AMD's next gen GPU architecture and not Vega which is a GPU architecture that released in 2017.

And I highly doubt they will even choose Navi, but it really depends how long AMD flogs that horse.

Well. It certainly didn't use Vega like many claimed. - But it did turn out it is using Navi, albeit a deviation of Navi as it's a custom design implementing aspects from AMD's next-gen GPU uArch like hardware Ray Tracing.
