| Fei-Hung said: Agreed. I can see Sony adding a custom audio chip, dedicated RAM for the OS, chip to help boost VR performance and sticking to dedicated 12TF for gaming to keep the price down.
Dedicated 12TF will help get the native 4k performance across most games without compromising on a sloppy OS and losing performance in VR. |
A 12TF GPU will be more than adequate for 4k games at well above 30fps if all other aspects of the GPU sees similar tech advances. Not all TFs are the same. Basically, 6TF in whatever GPU architecture used in 2020 will be better than the 6TF found in the polaris architecture today. And this is something else a lot of posters here aren't taking into consideration.
And not all aspects of game design scale up with the resolution. Eg; if a game is using a 2TF GPU to render at 1080p@30fps, you dont need 8TF GPU to render it at 4 times its rez. There are also a lot of other things like bandwidth for instance that affects how a game performs.
Fact is, with a much better CPU, and as little as an 8TF GPU on a more advanced GPU architecture, memory bandwidth in the 500GB/s range and 16GB of dedicated games app ram, we will have games that look significantly better than what we have on the PS4 today and running in 4k@30fps with high quality textures across the board. Maybe some games will run at 1800p if targeting 60fps. with 10TF they now have room for next gen assets and features or improvements in tech that we simply aren't seeing today on top of that.
With 12TF they have more power than they would need for next gen 4k gaming in a console form factor.
Now having said all that, I don't even think we will end up with a 12TF GPU. I think it will be much more. At least 15TF if not 16TF on an APU design and as much as 20TF+ if going the discrete CPU/GPU route.
Its easy to get misguided when looking at the GPU TFs alone as an indication of what next gen would bring. But thats just one part of the equation. The reason the PS5 will be much better than the PS4 is because everything will be much better. CPU/GPU/Ram/Bandwidth/IO bus/Thermals....etc. Everything.
