And how much can you realistically let 3 versions diverge. AAA PC games don't support 9 year old hardware, definitely aren't tied to having to run with 256mb video memory, 1GB system memory. It's always easy to say that we have plenty of memory now. 8GB seemed crazy 5 years ago, heck the ps4 almost launched with 4GB. Now the 5GB available is already cramped again. Not a good idea to stick with that until 2025 (NEO has the same memory, slightly faster speed) Nor the 8 core Jaguar at 2.1 Ghz.
Tech is slowing down is used a lot as an excuse. While that's true for processor speed, for parallel processing we're still in the early stages. GPU techology is still moving on, transitioning to finFET or 3D transistors which allows to go down to 14nm GPUs with more CUDA cores. 16 core CPUs are already here and AMD is also planning to use finFET for their 32 core Zen processor. Anchoring to only being able to use 6 Jaguar cores is going to look really stupid in 2025.
Imo enforced forwards compatiility will slow progress down. Yet if you just want the same games in a higher resolution, I guess the incremental model works for you. I hope Sony makes it clear what their plans are at E3 going beyond the NEO.
I think the problem with you and this thing is that you don't really understand or are allowing yourself understand how this works. You keep talking about support for older hardware as if everything else but the console lives in a vacuum. Pls take your time and try and look at this. And not just start reading it with nothing but a quick comeback in your head.
PS4. (2013) Designed to run games at 900p/1080p@30/60fps. 8GB/8CPU cores/18cu GPU is sufficient for this task.
PS4k (2016) Designed to run games at 1080p@30/60fps but hardware upscale them to support 4k rez. 8GB RAM/ 8 CPU cores/ 36cu GPU is sufficient for this task.
PS5. (2019) Designed to run games at 4k(native)@30/60fps. xxGB RAM/xxCPU/xxGPU is sufficient for this task.
PS5k. (2022) Designed to run games at 4k@30/60fps but hardware upscale to 8k......etc.
if in 2021 a game is released, and all you have is a 1080p TV, then you need not worry if you have a PS4/PS4k. Cause those consoles are all you need to run that game.at 1080p. If you happen to have a PS5 tho, then that game will run natively at 4k on your 4k TV.
That is how a system like this works. Unless you feel that game design requires leaps in hardware like what we saw betwen the PS2>PS3>PS4. Where memory goes from 32>512>5GB. so basically for your idea of next gen we should be having at least 50GB of RAM consoles. It just doesn't work that way anymore.
And that talk about 32 core processors..... you have been whining about how hard it would be for devs to support multiple skus of the same platform. yet you think it's easy writing code as complicated as game code to take advantage of a 32 core cpu?????? Ridiculous. Just look at how much of a nightmare it was programming for the PS3.
