PS5 Will Release Early 2019 (Opinion)

 Because of diminishing returns. We've reached a situation where graphical improvements are so hard to see, that it takes a lot of power difference to make it noticeable.

Isn't that what people said about PS360 to PS4/One? That really isn't a compelling argument.

A PS5 with the capacity of a GTX 1080 would only be able to show PS4 graphics at real 4K, but beyond that, you would hardly notice the difference between both consoles at Full HD.

Alright, and how do you prove this? What constitutes to being 'noticeable'?

Well, let's look at PS4 and PS4Pro GPUs

PS4 features a 1152:72:32 part, so it has 1152 shaders and 72 texture units, and it's based on Pitcairn, maybe Tahiti architecture.

PS4Pro has a 2304:144:32 part, with 2304 shaders and 144 texture units based on the improved Polaris architecture with some Vega enhancements.

What we see is that PS4Pro's GPU has more than twice the power of a PS4, yet what is the best it can do? Increase the framerate (which is also CPU dependant), increase the resolution from sub 1080p to Full HD and add slightly better lightning and textures (enhancements that require Digital Foundry's close up analysis to notice, because we can barely see them during gameplay) or run the game at higher res and then make a 4K checkerboard interpolation. That's not much for more than twice the power, don't you think?

Now let's look at Vega 64, AMD's counterpart to the Nvidia GTX 1080, and we see that it's a 4096:256:64 part featuring 4096 shaders and 256 texture units. So, even accounting for its architecfural enhancements, Vega 64 is not twice as powerful as a PS4Pro or RX 480/580 GPU.

Sure, it will be able to run Vanilla PS4 games at native 4K which, given how much do both Sony and MSoft talk about it, seems to be the goal for next gen consoles as far as resolution goes, but can it do that while also displaying better, more detailed graphics to a degree where we can see them without resorting to DF or other kind of exhaustive comparison sites?

I find it doubtful.

 

Side note: I've taken the GPU info from both this wikipedia page with all ATI/AMD GPUs and also TechPowerUp's database, in case you want to check them out.
