UPDATE #2: Sony has issued a statement:

We would like to clear up a misunderstanding regarding our "direct" and "flexible" memory systems. The article states that "flexible" memory is borrowed from the OS, and must be returned when requested - that's not actually the case.

The actual true distinction is that:

"Direct Memory" is memory allocated under the traditional video game model, so the game controls all aspects of its allocation
"Flexible Memory" is memory managed by the PS4 OS on the game's behalf, and allows games to use some very nice FreeBSD virtual memory functionality. However this memory is 100 per cent the game's memory, and is never used by the OS, and as it is the game's memory it should be easy for every developer to use it.

We have no comment to make on the amount of memory reserved by the system or what it is used for.

Based on this information, plus the new source coming forward to explain the properties of flexible memory, our take on this right now is that there is 4.5GB of conventional RAM available to developers, along with the OS-controlled flexible memory Sony describes, in addition to that.

We understand that this is a 1GB virtual address space, split into two areas - 512MB of on-chip RAM is used (the physical area) and another 512MB is "paged", perhaps like a Windows swap file. But to be clear, of the 8GB of GDDR5 on PS4, our contention is that 5GB of it is available to developers.

The good news is that the amount is static and not dictated by OS functions as we stated in our original post, making it a lot easier for developers to work with.


... and now XBone have more ram for games :  5GB+32MB > 5GB.

LOL XD

There you have it folks. Sony issued a statement and came with a no comment on how much ram is available for games. Rumor is true.


Yeah, like the 12Gb of RAM for the Xbox One.

I suppose X-box fans has spent so much time disliking the reality so in the end they turn rumor's lovers and believers.

Anyway... the whole show has been quite amusing.

I didn't pre-order a Ps4 yet, but if i may make some one happy, i can reserve one and cancel it few minutes later. (Just saying)

What are you talking about. All we heard was that the Xbox One is a media box, tv, tv, tv, etc. You can't deny all those comments. They are totally separate from the DRM fiasco and were only said by PS4 fans. Now I guess this makes the PS4 a media box right? If not then a lot of people on here should apologize, but of course they wont. This is seen as a good thing all of a sudden because it is Sony.


What are YOU talking about? "real" xbox fans were the only ones liking the whole tv, sports crap. All the hardcore gamers was bashing the Xbone from left to right. didn't matter if it was the Sony fans or not.

No it was Sony fans. Xbox fans actually listened when they said E3 was about the games and the reveal was about the media functions. Sony fans immediately ignored this statement and bashed Xbox One to no end with media box chants and TV, TV, TV. You can't deny it. Sony on the other hand did their usual hush hush and play the "we only care about gamers" card and tried to hide this ram issue under the rug. Unfortunately the truth has come out and the PS4 is just as much as a media box as the Xbox One.

Not really earth-shattering, I doubt devs would go and waste the entire RAM at this early part of the gen.

well, sony's spokesperson nr. 1 jonathan blow complained about the xbox one with "only" 8gb and 5gb free for games because his game already needs 5gb and like he said "it's only an indie game".

if this will be true i'm looking forward to see him tweeting the whole day how bad it is for ps4 now but i'm sure he won't.

Update:  Jonathan Blow deleted his Twitter account.  Seriously.

Huh? I don't remember any comments like that, before and after E3. Maybe you were on N4G, or some other website.

I dont think he deleted his account. He just sent out a tweet.

yup and thats the point of his game. i remember him saying that open world games nowdays are all about HUGE spaces, but he wants to make the experience of an open world game in the smallest open world. he wants to have the experience and content be as meaningfull as possible. i remember that was his goal with the witness


5 GB for that though? I can understand 5 GB for the next GTA but this? I wanna know what makes his game need 5 GB if it really runs on 5 GB.


Maybe the game is coded in Java.


LOL
