| CrazyGPU said: 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: Now, in this gen of console wars, hardware is about teraflops and graphic resolution (Im not talking about soft, exclusives, policies, etc, just hardware) |
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: 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: PS5 needs to be 3840 x 2160. A 4k native console. So If we want it to handle the same games with the same shading and lighting as ps4, no improvement, just 4k native resolution for the same game. it needs 8,3 megapixels per frame. |
It doesn't need to be anything. Like every other preceding console generation, resolution will be completely up to the developer.
The Playstation 4 isn't even a true 1080P console, many games operate at 900P. Or 1600x900 rather than the full 1920x1080 resolution.
The Playstation 3 had games than ran at sub 720P resolutions.
In-fact the base Playstation 4 supports HDMI 1.4, so in theory it could do 4k30fps if sony/developer allowed it and the visuals were dialed back.
| CrazyGPU said: And we can have that by 2019-2020. Xbox one X is 6 Tf and just lauched. |
The time frame of when the Xbox One X launching is ultimately irrelevant.
If the technology doesn't exist in the PC's mainstream, then it's never coming to a console, it is simple as that.
As for flops, again. It is a useless denominator, you can have a graphics processor with less flops outperform a graphics processor with more flops. It's stupid and nonsensical because games actually need more than just flops to render a scene.
| CrazyGPU said: PS3 cell processor was fabricated on a 90 nm process. That means each transistor was 90 nm in size. |
Are you sure about that? 14nm finfet is actually based on the 20nm planar process.
Don't fall for the "nm" marketing angle that fabs push out, they fluff up the numbers to make themselves look good.
You should try checking out the individual BEOL and FEOL sizes sometime at each geometry size, you might walk away a little surprised.
And that is the reason why Intel has typically held the fabrication edge... Because even though Global Foundries has a "12nm" process, Intels 14nm+++ likely has the edge still.
| CrazyGPU said: PS4 Pro APU was fabricated on a 16 nm process and most likely PS5 will be fabricated with 7nm transistors. |
7nm is a given.
| CrazyGPU said: 1 nm is the size of 10 Hidrogen atoms. So we are talking sizes of 70 atoms for a transistor. They don´t have much room left for miniaturization. |
Citation needed.
| CrazyGPU said: Its getting more time and its harder to make smaller transistor fabrication processes. And because of Quantum Mecanic laws, the performance gains they are getting are also smaller. So it will take a really long time to get to let say 3 nm and really really expensive. If the way of making processors doesn´t change, there is going to be a wall soon. |
DRAM/NAND have taken note of this. So instead of going smaller, they went taller.
More exotic materials like Carbon nanotubes and using triple/quad-druple patterning will go a ways to get us to smaller geometry sizes.
| CrazyGPU said: Even Nintendo said that getting into HD was way more expensive than developing for SD. |
That's just simplified rhetoric. Building a game for SD or HD costs exactly the same, the PC you can take any old game and drive it's resolution from 480P all the way to 8k, it's just a resolution change often exposed by a configuration file if it's not listed in the games settings.
It's building the assets that look great at higher definition that costs.
| CrazyGPU said: 4K AAA are even more expensive. Developers are facing a problem with it. So they sell DLC , implement microtransactions, etc. How much would developement cost increase for 8k? |
The real issue is likely the publishers. They consistently post ever-increasing-profits numbering in the Billions, they are not doing it as hard as you think they are.
| CrazyGPU said: FOR A PS6 TO HAVE A REASON TO EXIST , it should be a 8k console. Even at 8k we´ll have diminishing returns in graphics. |
Why should 8k be a requirement for the Playstation 6?
| CrazyGPU said: Of course I can be wrong, but for that companies need to change the way they make CPUs and GPUs to get better performance faster or there has to be a VR fever so high that millons of people pay more for beast consoles and companies fight for 4k on each eye at 90 fps. Not there yet. |
There is a focus on efficiency right now, not brute force with graphics. Consoles are simply at the mercy of the PC's development cadence on this front.
| CrazyGPU said: There also can be a new console with the same resolution, but would it make sense? |
Sure it would make sense. More to graphics than resolution.
| CrazyGPU said: If the console is powerfull enough to have real global illumination, raytracing or something game changing like that in order to have a reason to exist, then it would be capable of hitting 8k with todays graphics anyway. If not, it wouldn´t make any sense. |
Game engines are already leveraging global illumination and ray tracing to an extent where it makes sense and where the hardware affords such an approach.
