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

You do.

Just for comparision's sake RX Vega has less than 500GB/s even in the liquid version which clocks in at 13.7 TFlops which by 7nm will be about the maximum a console can reach before getting too expensive even by 2020-2021.

What you failed to see possibly is that in the last couple years several techniques had been developed to limit the bandwidth consumption of GPUs, with low-level programming further toning it down (less drawcalls and unnecessary transfers). Without those the Switch would be choked by it's bandwidth, as would Smart devices and APUs. And GPUs also, because then we would already need more than 1TB/s in Bandwidth in high-end GPU

Switch is choked by it's bandwidth and so are high end gfx cards ... 

"Draw calls" is just hype, that mostly helps at the CPU side but not so for the GPU side and low level programming mostly improves shader throughput but if you're hard limited by bandwidth there's very little a GPU could offer in terms of hardware feature set that you could use to alleviate it ... (aside from maybe some sort of compression formats or doing data packing tricks)

But not nearly as much as you think. Especially not in consoles where limits are put into frame counts. If you Vsync a GTX 1080 at 60FPS bandwidth becomes basically irrelevant as it doesn't come close to being choked by it anymore.

Besides, at 4K, the bandwidth is negligible as the raw power of the GPU is the limiting factor by then. Even a 10% bandwidth increase often only results in 1-2% performance increase in 4K, if any at all.
