x16 does make sense, though.

+ PlayStation releases every 6-8 years ? which would be 2^3 or 2^4 ≈ 16

Holy crap, proof!

I don't think so. I don't see any of the next generation consoles having more than 32GB of RAM. It's not that they CAN'T put in more than that, it's more about diminishing returns.

That's why we don't have 8 gb this gen, right?

The reason for rapid increase in RAM of the earlier consoles was mainly because they are starving of RAM.

PS1 had 2 MB Main + 1 MB Graph + 0.5 Sound RAM

Moden PC had 16 MB Main + 2-4 MB Graph

PS2 had 32 MB RAM Main + 4 MB Graph

Modern PC had 128 MB + 32 MB Graph

and so on...

So the tech was advancing very rapidly. This is actually the first time in consoles history, the RAM in consoles is more than an average PC. The graph in the last generatin consoles with 256-512 MB RAM is comparable to PCs with 4 GB. Also the installed RAM has NOT been increasing fast for the last decade. In 2008, for example, an average PC had 2-4 GB RAM, while today it has 6-8 GB. Not a big improvement in 6 years. You can expect a similar increase for the next console, especially given that RAM is the last thing they are craving for now.

PS5 will have 2-4x CPU power, 4-8x GPU power and 2-3x RAM, and that's about it. Don't expect miracles.

yeah, i was going to say this exactly.  even on the PC side the ram growth has kind of stagnated.   16 is an absolute floor.  32 is the likely minimum.  i could see up to 64 if they think it will be useful to developers.   ..but i kind of don't think 64 is likely.   we can already see the movement towards "the cloud" so i doubt we'll see a massive user side increase in specs.

Ask for more than 100GB of RAM is ridiculous. 32GB is more likely, with 64 being the absolute max. There's no point in adding more RAM.

Ps5 131gb Ram

hmm... something is wrong...

Atari 6900 1337gb Ram

That's better!

I am willing to bet my left testicle that the next generation of consoles will not have more than 32GB or RAM at the very most. And even at that only 28GB will be availeable to devs and 4GB reserved for the OS.

Games just don't or won't ever need that much RAM. Having 64GB of RAM in a console will pretty much be the equivalent of having a 64GB cartridge in the console.  Just makes no sense when you consider that no loaded level or scene will ever likely be more than 3-4GB of unique data.

I think the areas where generational developments in hardware will be made are things areas that we aren't really talking about now.

And the kinda stuff that "the cloud" can help with as far as running games are concerned use up very little actual RAM to begin with. Unless the entire games are going to be run off the cloud. Which is not going to happen. The cloud will never become the default way of playing games until it has first become the default way of watching live TV.

Well, won't ever might be false, too, as we don't know how much tv's will evolve or how much new rendering techniques will be demanding but it's definitely not next gen.

Prinz said it earlier and is correct. RAM is not a bottleneck anymore for games with 8GB. The problem now is speed of the RAM.

This gen will probably last shorter than last gen too, so 32-64GB is what I would guess. But with RAM prices probably be so cheap in the future, it might not hurt doubling down. No HDD needed, just RAM!
