PlayStation 4 OS uses 2 cores and a whopping 3.5 GB of RAM

PlayStation 4 RAM
We originally thought that the PlayStation 4 reserved 1 core and 1 GB of RAM for its operating system. Now Sony has revealed the truth, and it’s much scarier: The PlayStation 4 OS uses two out of the 8 cores, and a whopping 3.5 GB of RAM.

Sony’s PlayStation 4 design docs reveal that developers have “guaranteed” 4.5 GB of system RAM for their games, which can be boosted to 5.5 GB in certain cases, if the developer needs more memory (and Sony would have to approve of this).

This is a big revelation, as it shows a massive OS that runs on the PlayStation 4. The Xbox One uses almost as much, as it has reserved 3 GB for the OS. This is a tremendous jump in memory OS requirements compared to the current generation, where the PS3 and Xbox 360 use around 50 MB (MB!).

When the Wii U was revealed last year, Nintendo was ridiculed for using 1 GB of system RAM (50%) for the OS. Now that pales in comparison to the PlayStation 4 and the Xbox One.

We keep praising the PlayStation 4 for its 8 core CPU and 8 GB of RAM, but the truth is, games will only use 6 cores and 4.5 GB. Which doesn’t sound as impressive, to be honest.

    WTF sony!

  • HustyparmenCZ

    well…got PS4 for games, PC for the best graphics. I prefer Dualshock over mouse and Keyboard + there are not as many good games for PC.

    • RECKLESSgoat

      Dont forget thee 2 cores.

  • RECKLESSgoat

    Omg, sony you lied, looks like the xbox one will have more usable ram now. That was a bad move by sony. I think they should have told us the truth earlier!

    • HustyparmenCZ

      they didn t lie, and now xbox has 5GB of DDR3 for games VS PS4 4,5 – 5,5 GB of GGDR5 ram ..still a lot better and 50% faster GPU + Xbox uses 3 out of 8 cores – so xbox 5 core vs PS4 6 core for games

      • RECKLESSgoat

        The PS4 OS was only gonna take up 1GBof RAM, they multiplied that by 3.5 -.- from 7 usable GB’s to 4,5…

        • HustyparmenCZ

          I think they probably changed it in order to be able to compete with Xbox – all that multimedia crap etc. Which still sucks..

          • RECKLESSgoat

            I am not even intrested in that crap, sony shouldnt have done this -.-

      • Arthur Hughes

        With Xbox one using a hypervisor it could go past the 5gb with no problem at all.

        • http://www.facebook.com/people/Omar-Bachara/1201000990 Omar Bachara

          The PS4 OS is based on FreeBSD9.0, which should take less ram so this can’t be true

          • Arthur Hughes

            not sure what this has to do with hypervisor, and how a magical man name omar knows what the OS does and how much space it uses

            Edit: Just noticed that you were that retarded kid that said Timed Exclusive on DR3 like he knows something magical their too. Hopefully you will hold your breath till microsoft publishes it on the ps4

            pussy

          • Arthur Hughes

            boy you are a sad little puppy arent you.

      • Laud

        Yeah but… games don’t even utilize 4 cores yet lol.

        You won’t really see a difference in graphics between the two consoles until late in the game when the Xbox becomes more limited which to be honest I don’t think will happen any time soon.

    • bizzy gie

      This is a rumor you Xbox fanboy.

      • LEGENDKiller

        Wow you just can’t help yourself smh, guess it’s in your nature in attacking others who’ve a different opinion then you..Please explain how he’s a XBox Fanboy?despite him saying many times he’s getting a PS4. Reckless is trying his best not to be biased..

        • RECKLESSgoat

          Exacly, I even own a ps3 and game on it.(mainly) psn=RECKLESSgoat

        • bizzy gie

          Excuse me. I’ve seen several negative posts from him about PS4 on PS4 and xboxone daily.

      • RECKLESSgoat

        What are you talking about, I game on ps3 -.- I will also be buying the ps4, if you dont believe me then inbox RECKLESSgoat on psn and I will reply to you.

        • LEGENDKiller

          bizzy is obnoxious, like most of Sony fanboys only values your opinion long as you praise Sony 24/7 and 365 days a year, his loyalty is to no-one except for a big business company named,Sony.

          Saying, you don’t have prove yourself to him..

          • LEGENDKiller

            bizzy, Shut up you Playstation Fanboy

          • RECKLESSgoat

            I actually agree with you, before when people called him a fanboy I didnt really understand why they did that cause I thought he was just pissed at MS for what they did, nothing more. Now Sony lied, thats worse than what microsoft did… yet bizzy is still by there side, if it was microsoft who lied he wouldve filled the forums with his comments saying how bad MS is.

      • RECKLESSgoat

        oh and btw…

        not a rumor anymore(5.5GB of usable RAM)

  • odoutor

    this is a rumor

  • http://www.facebook.com/people/Omar-Bachara/1201000990 Omar Bachara

    I blame all you shit tards that kept complaining about the XMB saying it was too plain. I loved the simple and quick to use XMB now sony is like you want more OS u got it at a cost bummer.

    • HustyparmenCZ

      funny thing is PS4 OS looks almost the same..and PS3 OS takes only 96 MB… 3500 MB vs 96 MB..wtf

      • HelterSkelter

        It’s called “future-proofing”.

    • RECKLESSgoat

      The XMB was okay, it just needed some improvments, but a 3.5 GB OS is not what we want Sony….

  • TomDobo

    The truth is revealed i knew it was too good to be true for ps4 fans looks like xbox one was the right choice

    • Mikey Styles

      This “opinion” above is why people get into silly arguments. As the Xbox None uses 6cores & 5GB of RAM so .5GB of difference on slower bandwith memory pretty much makes this a push. This is a non issue to me as more intuitive UIs will tend to take up more memory.

      • TomDobo

        Gddr5 reads small amounts of data fast and ddr3 read larger amounts of data slower so there basically the same plus xbox has 32mb of esram and heavily dependant on the cloud for more computing power. so id say there pretty even at this very moment. This console war get more and more exciting with each passing day. This is the only bad news ps4 has had xbox one is full of bad new which they have nearly sorted it all out now.

        • Mikey Styles

          I understand all of that & agree for the most part but latency in ddr5 ram is much less which is a big plus. & the .5GB isn’t enough of an issue for me. Not to mention how resource hungry Windows 8 is so again not trying to argue just not as big of a black eye. We also know the permissions to work with an Xbox as a developer has turned into a nightmare.

          • TomDobo

            We are not arguing its a discussion i absolutely love the ps4. Its just i love halo gears of war and Forza otherwise i more than likely would get a ps4 all I’m trying to say is i don’t think there will be a big difference in terms of graphics or smoothness of how it plays these will be both brilliant consoles with their own pros and cons.

          • Arthur Hughes

            Care to prove your last statement. Seems they have done nothing but make it easier

          • Mikey Styles

            Ya they have, since getting hammered by almost every media outlet which would include pro-xbox media. Maybe I mis-typed but you get the basic idea & what else did Microsoft 180 on this week Lol

          • Arthur Hughes

            Great non answer, Good to know your just a troll kid that posts Crap.

          • Mikey Styles

            Wow Really dude!? You need to take your Adderall….How many websites or news posts have you seen all saying that Microsoft has made everything very difficult till basically flip-flopping a policy(s) or a requirement(s) for user & developers alike. This site posted an article back around E3 showing this which most of has been 180’d by Microsoft.

          • Arthur Hughes

            Ill give you one more chance to prove your statement. or fall to the ranks of a troll like bizzy gie

      • HustyparmenCZ

        xbox is 5 core / 5 GB for games ( 3 GB and 3 cores are reserved for OS , kinect etc. )

        • Mikey Styles

          My Bad was using my phone meant to put that. Thnx for the correction.

      • Mucksony

        This article is a rumor but it also says you can use 5.5 not 4.5 if needed

  • RetroReese88

    “Now Sony has revealed the truth, and it’s much scarier” When did they reveal this? As far as i know it’s a…”RUMOR” and nothing more.

    • Arthur Hughes

      Sony’s PlayStation 4 design docs reveal that developers have
      “guaranteed” 4.5 GB of system RAM for their games, which can be boosted
      to 5.5 GB in certain cases, if the developer needs more memory (and Sony
      would have to approve of this).

      Reading comprehension fails you

      • RetroReese88

        RUMOR…please show me these docs that developers have. I read the article over and over and it clearly states it’s a RUMOR.

        Reading comprehension fails you.

        • TomDobo

          Explain why the artical states now sony has revealed the truth ?

          • RetroReese88

            Yes. How have they revealed anything when sony haven’t confirmed or denied anything. At the moment it’s just a rumor and people don’t seem to get that, just like X1 getting a ram boost…just a rumor until confirmed.

        • Arthur Hughes

          Hey derp, it does not say rumor once in this article, nor is this article posted under rumors.

          Actually access to 7gb is posted under rumors right here on this site http://ps4daily.com/2013/04/playstation-4-developers-7-gb-ram/

          • RetroReese88

            Dude im not about to argue with someone that takes rumors as facts, if you believe it so be it good for you. Like i said show me docs or sony saying it’s true until then it’s nothing more than a rumor.

          • Arthur Hughes

            its ok man, you will be able to learn how to read one day, Just keep working at it. I would recommend reading a book or 2 a week it will help you out.

          • Mucksony

            The Last of Us did not even need 1 GB of Ram lol

        • Arthur Hughes

          lmao i just went and read the entire eurogamer and not a single mention of the word rumor. wow you are a delusional little kid

          • RetroReese88

            “according to current PlayStation 4 documentation shown to Digital Foundry by a well-placed development source” That’s a rumor and just about every site lists it as a rumor lmao, i read it at ign which clearly stated it as a rumor. Dude if rumors=facts to you, cool move on lol.

          • Arthur Hughes

            I feel sorry for you. Keep on believing its a rumor

          • RetroReese88

            http://www.youtube.com/watch?v=yIGmzzi0TSM This man says it all. The funny thing is no one from sony confirmed this and you take it as fact lol. Feel sorry for what because a rumor don’t effect me,either way im getting my PS4.

          • Arthur Hughes

            listening to a retarded kid with an iphone with wind blowing over the mic is a great way to prove a point. sorry i only made it 10secs beofre i cut it off

      • Mucksony

        IGN and every other gaming site also reported it as a rumor atm no confirmation from Sony

        • Arthur Hughes

          This gaming site and Eurogamer, The source of it report it as fact.

          • Mucksony

            Yes because Eurogamer is in Japan at Sony headquarters right

          • Arthur Hughes

            Go read the actual original story bizzie maybe you can figure it out from their. I doubt it takes an iq over 45 to figure it out.

          • bizzy gie

            That’s not me bro.

  • Mark Thom

    :O LOL

  • Mikey Styles

    I still think people are going a bit overboard & should enhance their inner calm lol. I can almost guarantee its needed for all the multimedia like the Xbox. Funny thing is they don’t have all of what Xbox does at this moment & will prob add going fwd. I’m also gonna take this as a rumor for now till its officially confirmed. Which still isn’t a big deal to me.

  • Ace J

    …AAAANNNDDDDDDD iam still getting the ps4

    • Arthur Hughes

      Why would you not, Its about games not system hardware or speed. Like ive said forever the power difference will be negligible. It comes down to just a couple things. Exclusive games (the 3 or 4 each system has that people actualy will buy) and Kinect. If you want to be more involved in your games and like motion control.

      • Ace J

        iam just surprised by all the negativity this article is receiving. thats all

        • Arthur Hughes

          Its receiving it because of the Sony troll kids running around saying the PS4 was a super console compared to the Xbox one. You keep poking people over and over, theirs back lash when something like this comes up.

          • Ace J

            i hate to be that one kid, i really do but i do feel like the ps4 is a “super” console compared to the xbox one lol

          • Arthur Hughes

            I feel sorry for you.

          • Mucksony

            PS4 has a better CPU, GPU, RAM than the X1 so yeah also a lot more game so far.

          • Arthur Hughes

            ITS BIZZIE GIE

          • bizzy gie

            No it’s not. I’ve been OUT with my family all day.

          • Ace J

            iam joking by the way lol. but real talk i dont like the xbox one

  • Mucksony

    This is just a rumor. They act like Sony confirmed it lol

  • JeanPaul

    This wouldn’t be such a big deal IF EVERYONE DIDN’T CONCENTRATE ON THE FRIGGEN SPECS! GAMES PEOPLE! GAMES!! The only news I see on the PS4 is about it’s specs!

  • alberty29

    Gamestop call me! The preorder for The ps4 open tomorrow!
    I was in a list of waiting

    The PS4 OS is based on FreeBSD9.0, which should take less ram so this can’t be true

  • Chris Brinkley

    Hope this just means on dev kits, where ram and cores might be taken up by dev tools. Am I right in thinking that to add a few more cores and more ram on top of the 8gb would be a technical difficulty due to it overworking other parts of the system, leading to the bottlenecking that Cerny spoke of trying to avoid? This might explain the 4gb of ram that devs have spoken of and why dev kits are so much cheaper than last gen, they might not yet have figured a cost effective way of adding the higher than retail specs in the devkits, say 10-12gb total, so doing it on the cheap temporarily while they can get away with it due to it being enough for the first wave of games. Obviously I don’t know what I’m on about so please see this as a question rather than a statement. Please don’t hit me, internet.

  • bizzy gie

    PS4 is still on top. Luckily, the RAM and CPU are faster than XB1’s so not too much loss.

    That’s if this isn’t a rumor.

    • RECKLESSgoat

      BUT… why didnt sony tell us this from the start? They said the OS was 1GB, THEY LIED(if this is not a rumor) if you have an “educated” explanation bizzy then go ahead.

      • HustyparmenCZ

        And u remember how Mark Cerny said 20th February – ,, Im proud to announce that we are equipin the system with 8GB of high speed unified memory! :)

        …he should add :- to make our 500mb OS systém grow into 3500mb !!! …wow right.

        • RECKLESSgoat

          The PS3 OS was about 100mb’s of RAM I believe, and now 3.5GB, they shouldve been honest about it atleast.

          • HustyparmenCZ

            I meant original PS4 with 4 GB was planned to have 512MB OS, so they add another 4 GB only to make that OS 3500MB, not to make games better.

          • RECKLESSgoat

            oh, lololo sony wtf :]

      • bizzy gie

        I do have an educated explanation.

        RU.MOR n. – a story or statement in general circulation without confirmation or certainty as to facts

        • RECKLESSgoat

          Then why didnt sony confirm that this is false just ONE simple tweet could end this…

  • dxcvs

    Who cares its ddr5

  • Jon

    Last I checked, Hardware… means jack all. It’s the games. I am not pre-ordering either system but I will wait to see what all comes with it before I decided on which one to get with my Wii U.

  • The Unknown Legacy

    There’s been an update on eurogamer’s site. Check it out guys: http://www.eurogamer.net/articles/digitalfoundry-ps3-system-software-memory

  • http://gradly.net/ Gradly

    Actually, Sony have commented on the post, check update #2, anyway, Games will have 100% access to apparently 5.5GB of RAM leaving 2.5GB reserved for the OS

    • RECKLESSgoat

      Saw that, 5.5GB is better than 4.5GB atleast but specs are not the problem. The problem is that sony tried to sell us the system with us having in our minds that only 1GB of ram was for the OS?

      • http://gradly.net/ Gradly

        Its true Sony kept itself tight-lipped on that but Its impossible with all (the sharing, always recording full HD 1080p, instant swapping, suspend games in RAM) to justify only 1GB cuz its not enough obviously, the most intrigued part was the OS using 3.5GB but now its 2.5GB which to me makes sense

        • RECKLESSgoat

          Yeah I guess we will have to see some really advanced OS from sony to make up for this, it takes as much as windows 7 does.(maybe even more)

  • Mitch Hall

    People can talk about specs all they want, but it doesn’t change the fact that we’ve already seen what PS4 games can look like – and they look great, in my opinion.

  • Jose Pacheco

    Well I’m not that surprised. Knowing that the ps4 had to pass FCC regulations. Did you actually thunk the US would let a Japanese company get away with what it was trying to pull on Microsoft??

  • DoUbLeZz (Lydon)

    Compared to the decent games we have now with consoles that only have 512 mb of ram, its really not that bad at all! =/ but ill admitt i am kinda hoping for a last minute announcement about, compressing the space that the games would originally take up or 1 extra gig of ram being added! =P
