So much nonsense being written here and in other forums. The situation is like this:
On a PS4 developer unit, you have 8G of ram divided into (numbers heavily rounded):
1G os
1.5G debug software
1G debug scratchpad
4.5G game (or 5.5G if using the debug scratchpad)
On a PS4 end user unit, you have:
1G os
5.5G game
1.5G unclear space (now os scratchpad space?) as there very likely isn't any debug software loaded
So on a PS4 end user unit, the ram limit is >= 5.5G for the game


Usually I appreciate your posts but this one... Unless you can prove it, then devkits usually are equipped with more ram than the retail console. That's where the 1.5g debug seems to be wrong. But either way I think 5.5g is still enough for nowadays games.

drkohler said that because the DF article seems based in the Killzone documents that was running in a 8GB DevKit machine... DF didn't have access to the final devkit with 12GB and even most developer didn't received the final devkit.

The old OS used 1GB of the RAM... now the new OS (I think like Sony upgrade to 8GB they can use more RAM for the OS) is supposed by DF to use 2.5GB for OS.

But DF supposed that based in the Killzone running in the old devkit.

For now is just a wait...


no it wasn't "based" on it. read the gaf-thread, it there to further support the idea.

"Sony's internal docs say that 4.5GB is the baseline amount of guaranteed memory available for game-makers (note the memory usage of the Killzone: Shadow Fall demo)"

The DF article is based in the old devkit used in Killzone demo lol

I'm just commentint what I read in the article.

I'm calling bullshit. There is just no way the OS is using that much. Unless they haven't showed us something unexpected.

Nope, I think they're were just lying, AS USUAL. And typically tellying the fanboys what they what to hear - 7GB RAM for games lol,...what a load of BS. And I would bet that this is only the begining of such annouments to leak out about the PS4.

Sony lied, despite never saying a single word about how much RAM is available to games?

Those sly bastards.

bastards in deed,...just typical Sony behaviour, nothing new here.

I love My Wii U, and the potential it brings to gaming.

no it is based on internal docs and they wanted to support that further.

This new gen should be called "The RAM wars".

So the console parity continues the closer we get to launch. Nothing new.

I find it hard to believe that it's using more ram for the OS than the xbox one is, despite the fact that xbox one has 3 os's and is touted to be the "all in one console" and GDD5 is supposedly faster. I'm gonna put this rumor in the - Eurogamer is full of crap pile.

Some neogaf insiders already confirmed this

Not a big deal just yet, although it is a bit alarming. They need some extra RAM for the OS for possible future updates, and if they ever decide they don't need more, they'll just give the extra back to games. It's not like games in the first few years are going to require more than 4.5 GB of RAM. Later in the console's lifecycle, though, things could change, and Sony should really try to reduce the amount of RAM used by the OS.
