I guess the PS4 is more of a gaming consoles than the WII U is LOL.

That my guesses now but the OS uses 2-cores of the x86_64 CPU and over 2.0GB of the GDDR5.

We don't have the numbers from sony to confirm. Afterall the PS3 used something like 40MB for it's OS.

The PS3 used even over 100 MB for it's OS after the launch. The OS footprint was reduced over the years: http://community.eu.playstation.com/t5/PlayStation-3-General-Discussion/PS3-OS-memory-footprint-slashed/td-p/9874872

I expect similar OS-optimizations for the PS4, XBO, WiiU, 3DS and Vita i the next years.

I actually don't expect optimization for the PS4 since processors aren't allowed with multiple memory controllers. It looks like the OS will use 256MB for it's whole life and I doubt games will use it since access times will probably be incredibly shit.

I'm talking about reserved GDDR5-RAM for the OS, the 256 MB DDR3-RAM have nothing to do with it.

Official number please ? (Sony hasn't even disclosed it yet. *rolls eyes*)

PS4 OS footprint now: x GB

PS4 OS footprint next year: <x GB

Happy?

Thats only if optimization can offset additional features that will be rolled out over the coming year(s).  and since we dont know what future ideas might blow us away and become huge in the gaming world, its hard to make a difinitive statement like that.  Sony wants to reserve space incase it needs to.   with any given update if they decrease the footprint, they would still most likely reserve that space incase its ever needed in the future.

So you're *rolling your eyes* at your own claim too? That "it looks like the PS4 will be stuck with only 256MB of RAM for its whole life"?

Who knows? But I think you were onto something when you mentioned how Sony hasn't officially disclosed everything yet.

Think of it like this. Sony has probably went back to the "console must strictly do gaming and fuck everything else" route. It's pretty safe to assume that sony probably won't be using that "it can only do everything" slogan anymore LOL. All in all it's pretty safe to assume that sony didn't go for a bloated OS so it might actually only use 256MB for all I know since the ARM processor is used for "background tasks" to which I implied it would handle the OS and other things too where the whole 8GB as well as the APU is dedicated to just being there for performance.

Ohhhhh guys there are a lot of contusion here....

The PS4's OS reserves memory from GDDR5 for it and apps... the 256MB DDR3 is for the background processor not related to PS4's main OS.
