I will split the posts cause its getting too long explaining a little more

Let asume, as most analysts and people guess, that PS5 would be released 2020 or 2021. With a 7nm fabrication process, and enough power for 4k 30fps gaming.

Will it though? I think people underestimate how much resources you truly need to achieve 4k30fps and have an accompanying generational leap in fidelity.
CrazyGPU said:
I said 4k 30 fps, I didn´t say that it will have an accompanying generational leap in fidelity. I would be glad if it really achieves native 4k 30-60 fps in all games. What you say would be a dream, but far from real for PS5. I can´t see them achieving a gen leap in fidelity in 3 years with today hardware on console power envelope at 400-500
And with 8 Tflops don´t expect nothing more than medium quality 4k native graphics.
Again Teraflops are not exact, if AMD changes radically its architecture or Sony goes for Nvidia , the number of Tf will change, but I need something to relatively compare.

Now, in this gen of console wars, hardware is about teraflops and graphic resolution (Im not talking about soft, exclusives, policies, etc, just hardware)
Permalite said:
No it's not about teraflops.
That's just advertising fluff so that one company's platform looks better than another and people who don't know any better take that number and run with it without any understanding of it's implications in relation to hardware capability.
This has happened many times in the past. - Like with bits or ghz.
And just like "bits". - Flops isn't an accurate denominator in determining the complete hardware capability of a console.
CrazyGPU said:
Yes, this gen is about teraflops and graphic res. Exactly as you said, people take that number and run with it. Its how Microsoft and Sony are fighting the marketing war. They don´t speak much about bandwith, geometry throughput, pixel filtering, texel filtering and the bottleneck of the involved CPU. That´s how they market the world how capable their console are, Tflops. It doesn´t mean its the only thing that matters, but its how they show their products. The first thing Ms said about One X was that it was a 6 Tf machine. They try to win user´s mind as Intel did with GHz 2 decades ago.

If we consider that PS4 is close to 2 teraflops for 2 megapixels per frame, then we would need a at least a 8 teraflop machine for 8 megapixels.

Correlation doesn't equate to causation. You are drawing a false equivalency which is a logical fallacy. Aka. Wrong.
CrazyGPU said:
Its math. If you want to output 2 millon pixels on screen you need 2 teraflops at a fixed quality(means without changing anything else, just resolution). Then if you need to output 8 millon you need 4 times that, at the same fixed quality. And that considering other stuff like say bandwith doesn´t become a bottleneck. If it does you need to balance that too. Of course if you want to implement better AA, shading, lighting, rays, etc, you would need even more power, which would mean even more flops for calculations.
Im not being extremely precise, PS4 is not 2 teraflops, its 1.84, and you get just a little more than 2 millon pixels on screen, but the idea is the same, as when someone says 1000 MB of ram is 1 GB and thats close to 1024, the right number.
