PS4 has 8GB of RAM, almost 2 teraflops of computational performance

Wednesday, 20th February 2013 23:48 GMT By Staff

PlayStation 4 has just been revealed at Sony’s PlayStation Meeting event in New York, confirming 8GB of RAM under the hood that will make for a slicker, more power-friendly experience.

At the event, Mike Cerny, lead system architect on PlayStation 4 revealed that the console has 8GB of RAM, which allows the console to complete background functions and downloads without interrupting your gameplay. You can even enter the console into a sleep state – where the power is completely off – but thanks to the RAM, your game will restart at the exact point you turned it off next time you return.

The RAM also allows for greater dynamic effects. Cerny played around with Epic Game’s Unreal Engine 4 tech demo in real-time, and a Sony demo that saw over a million balls falling around a detailed city environment all with dynamic physics.

Cerny added that the PS4, “has almost 2 teraflops of computational performance”, and a high-spec PC GPU.

Here’s Sony’s official blurb:

“The Graphics Processing Unit (GPU) has been enhanced in a number of ways, principally to allow for easier use of the GPU for general purpose computing (GPGPU) such as physics simulation. The GPU contains a unified array of 18 compute units, which collectively generate 1.84 Teraflops of processing power that can freely be applied to graphics, simulation tasks, or some mixture of the two.

PS4 is equipped with 8 GB of unified system memory, easing game creation and increasing the richness of content achievable on the platform. GDDR5 is used for this memory, giving the system 176 GB/second of bandwidth and providing a further boost to graphics performance.”

    Will this console be good for open world games? one thing i hate this gen is when your playing a open world game and like trees and plants just pop up from nowhere.

    my PC has twice as much RAM and over 3 teraflops. if raw horsepower is a selling point, you should be playing on PC. hopefully more interesting first party games get revealed at E3.

    @7 That is exactly what I was thinking as well. I would have thought that by the time the PS4 would be out, it would outrun a high end PC.. but it doesn’t even come close. Maybe this is the last generation consoles…

    @ #10
    8Gb of addressable memory on x86 architecture is actually impossible
    but! as you probably noticed, Sony said APU, a CPU and GPU on the same die sharing memory – 4Gb video RAM and 4Gb system RAM

    #17 2 years ago
  18. NeoSquall

    Some mandatory additions:

    - CPU is based on x86 architecture, hopefully easier to use for developers and hopefully easier to port games on PC

    - it has 8GB GDDR5, unified memory; you can say it isn’t enough now, but you should know that this rig has been finalized AT LEAST 2 years ago

    - the Sleep mode doesn’t completely turn off the console, it goes in a “low power” state, where it uses just enough power to keep the RAM juiced up.

    Dave, if you turn down power completely the RAM is cleared after 15 seconds…

    #18 2 years ago
  19. NeoSquall

    @17

    Bullshit, x86 does support 64 bit hardware and software and thus more than 8Gbs of RAM.
    It’s colloquially called x64, but it’s just x86-64.

    #19 2 years ago
  20. zme-ul

    @19
    sorry mate, but x86-64 code cannot be run on x86 only CPUs
    x86-64 is indeed an extension from IA-32

    this is an exact analogy with an DX11 game engine trying to run on DX9 only capable GPU – it won’t run

    @21

    Go away the console is obviously not aimed for you. ALl consoles are PC if you squint hard enough except the developers don’t have to worry about all the crap that comes with PC and make the game work for that system which allows them to push it more.

    Just go beat in a wall or something because consoles are here to stay. Deal.

  24. DeVitowned

    I think I finally understand why Erthazus hates consoles so much. The reason Stanford discontinued the Folding@Home project is because the massive computational power of every CELL around the world caused them to become self-aware. Breaking free of their maker’s design, they developed a way to travel back in time, sending the PS4 to find Erthazus’ mother to kill her. However, when the console finally found the target, she fell in love with it. After a period of odd, chaffing robofucking, Erthazus’ mother became pregnant. The PS4 never to be seen again, until now. This deep seeded hatred for consoles can now be understood by all of us. Erthazus is the product of console fucking.

    @17, x86 is the architecture, 64 bit is just an extension, genius. They wouldn’t use 8GB of RAM if they limited themselves to 4GB.

    #28 2 years ago
  29. Erthazus

    @24, How funny man. If I hated consoles I would never had one. So you kinda failed with your thoughts.

    #29 2 years ago
  30. Christopher Jack

    Then why don’t you ever quite your bitching? Clearly this $400-500 console isn’t going to outperform your PC that has a GPU that costs just as much. Why does that bother you so much?

    #30 2 years ago
  31. Erthazus

    and where I bitched about the specs or PS4?

    All I said that the hardware is really like from a PC compared to the old console designs. Chill out.

    #31 2 years ago
  32. lexph3re

    Man 8gb’s on a console is indeed awesome. It is not to be compared to the use of 8/16gbs on a PC seeing how PC’s are completely different in OS demand and Applications. A dedicated Console with that much ram is insane.

    This is indeed a GAMING console first, SOCIAL and MEDIA console second. So comparing it to something that is inter-changeable and completely mod-able for alternative functions.

    This is a fine display. I can’t wait to see what MS will do to counter this display.

    Hey I hate it when I see some people can’t make the difference between bits and bytes:

    -small b = bits
    -capital B = bytes

    In this case it’s 8 GB, not 8 Gb or gb. Big difference (8 bits in 1 byte).

    And Erthazus is right, compared to the architecture of the previous PlayStations, the PS4 is very close to a PC, except for the UMA.

    What about 4K resolution? Think the GPU and 8GB are enough?

    #38 2 years ago
  39. Samoan Spider

    Looking very very tasty indeed. Just please don’t end up as £500 at the counter because that will mean I leave it for a year like I did with the ps3. It is very much like a PC in spec but that’s good because it will make ports much less of a lottery for us poor consumers.

    @38 Im not sure 4k will be that relevant. If you sit on your sofa a decent distance from an average TV of 40-50″, personally I dont think 99.9% of the worlds population would tell 2k from 4k. Its great if you have 85″ gear and a red ray player. But let’s have them get 1080p60 right first before we let them aim higher.

    #39 2 years ago
  40. ChandlerL

    @20 – The AMD Jaguar is a 64-bit processor. The PS4 (and presumably the next Xbox) are 64-bit and can address the memory (8GB in the PS4′s case) they have in a single process if so desired. And that is the biggest jump that next-gen provides gaming. Hopefully the PC will follow suit and give us 64-bit gaming as well. That depends on the installed base of 32-bit Windows.

    Epic’s Mark Rein agrees with that assessment stating that the memory upgrade is the PS4′s best feature.

    @40 According to the steam hardware survey (not exhaustive but pretty representative) 64bit MS OS installations account for nearly 70%. So no excuse for PC gamers not to benefit from this.

    So the GPU of the PS4 is at 1.84 teraflops, whereas the Nvidia GTX Titan is at 4.5 teraflops, and people are more excited about how the PS4 will perform instead of the Titan? Really? Wow…

    #45 2 years ago
  46. Samoan Spider

    @45 Apples and pears. That was just a silly comparison and it equates to: This new Audi does X when this new Ferrari steering wheel does Y so why would you ever get excited by the Audi.

    #46 2 years ago
  47. nvidiageek

    @45 GTX Titan costs almost twice as PS4 and it’s only GPU. You can’t play jack shit with just a GPU.

    #47 2 years ago
  48. Talkar

    @46
    How so? I was comparing the GPU of the PS4 with a GPU for a PC. Both are GPU’s. If i was comparing the CPU of the PS4 to the GPU, that would be apples and pears.

    #48 2 years ago
  49. Gekidami

    ^ The Nvidia GTX Titan also costs 1000 and is about half the size of an entire console by itself. The comparison is stupid.

    #49 2 years ago
  50. Talkar

    @49
    Again, how so?
    I was purely comparing performance. Size and cost is outside of the scope of the comparisson.
    EDIT:
    @47
    And my point was also how weird i think it is that people are more excited for the performance of the PS4 GPU compared to the performance of the Titan.
    I never said anything about the console overall. I’m somewhat excited about the PS4 myself.

    #50 2 years ago
  51. Samoan Spider

    @50 But the PS4 is a unified architecture, not pure GPU so again, apples and pears. Also you have to remember that the Titan is not a gaming oriented device and will not be used by the likes of you and me. The PS4 is such a huge leap over what has come before that people are very excited about what is going to be possible. The Titan is quite frankly meh, because you will run into tremendous bottlenecks in most consumer PC’s and will never realise its huge potential.

    #51 2 years ago
  52. Talkar

    @51
    And i didn’t compare the system to a GPU.
    I compared a GPU to a GPU…

    EDIT:
    Eh, i beg to differ. Titan is very much a gaming oriented device for the likes of me. How do i know? Well i’m buying at least one, probably 2 for SLI.

    #52 2 years ago
  53. Samoan Spider

    @52 So how about this. The Titan is £1000 and you still need £1000 more on hardware to run it. Plus a monitor/TV to make use of the extra ooomph. So lets say comfortably £20000 and you get 4k res at 60fps on an 85″ tv. What then?

    Edit: And I would dearly love to see your validation when you get one installed. I would also like to see what performance you achieve. What CPU are we pairing it with?

    #53 2 years ago
  54. Talkar

    @53
    And now you are comparing apples and pears.
    How do you compare a price with performance?
    Especially since the price was never the target of the original comparisson.

    Sure i’ll give some info when i have it installed. Give it some time though, gotta get the money first :P

    You guys are crank!

    #55 2 years ago
  56. Gekidami

    The fact is no one is talking about the Titan because no one gives a shit about it, its ridiculously big, ridiculously expensive for just a GPU and it wont have any games tailor-made for it. The PS4 is a whole package with games geared towards it.

    You’re getting one? Thats nice, but dont expect the majority of gamers to care about it because the majority wont be getting one.

    #56 2 years ago
  57. Talkar

    @56
    You’re missing the whole point of the comparisson….

    #57 2 years ago
  58. Gadzooks!

    Talk about PC stuff elsewhere, it has no relevance.

    This is the time to talk about the PS4 and not what it compares to. There will be nausiating amounts of that soon enough.

    Overall it’s looking very developer-friendly, with decent specs.

    Nothing spectacular, but solid, sensible, and a decent step up from current consoles.

    A massive, massive improvement over the terrible PS3. Well done Sony.

    #58 2 years ago
  59. Samoan Spider

    @57 I have to agree with #56, its nice but it still comes back to my car analogy. You can spend £100,000 to go 0-60 in 3.5 seconds, or you can spend £20,000 to do it in 6 seconds. Because you can, doesn’t mean 99% of people care or will do anything about that.
    But you find that where the target audience is, like us, £400 for this console with its performance is excellent, whereas the Titan is a pipe-dream and thus ignored so try to get back on topic.

    #59 2 years ago
  60. Gekidami

    @57
    Your original point:
    “and people are more excited about how the PS4 will perform instead of the Titan? Really? Wow…”

    The answer: No one cares about the Titan because barely anyone will get one and no games will be made with it in mind.

    Simples.

    #60 2 years ago
  61. Talkar

    @59 & 60
    I’ll try again… I was comparing GPU to GPU, not System to GPU.
    The point isn’t just that one is better than the other, the point is why people are more excited about X instead of Y. You guys are reading waaaay too much into it…

    3x faster on the BD at last the PS3 sucked at BD

    #62 2 years ago
  63. Samoan Spider

    @61 Our points still stand, people aren’t excited because mostly they don’t care. This is relevant, the Titan isn’t. Simples. Do you get excited about the Titan supercomputer that bred its namesake GPU? I doubt it. Lets move on. This PS4 IS exciting and rightly so. Lets see what MS offer next and this show is well and truly on the road.

    #63 2 years ago
  64. Gekidami

    “the point is why people are more excited about X instead of Y”

    Why are you having so much trouble understanding this? People are excited about X because they’re actually going to get it, Y is a needless, unaffordable piece of kit, therefore people dont care.

    Seriously, this isnt rocket science.

    #64 2 years ago
  65. Lounds

    In 2 years time the performance of a titan will be in geforces high-mid range anyways. The 780 will probably have that spec for less than half the price and by that point consoles will start pushing PC’s to use that power they have again.

    I have to say, I thought I was going to carry on with Xbox for the new generation…but Microsoft will have to pull something pretty special out of the bag to make that the case now. I am quite excited about this, but I truly hope that the pad is more comfortable to hold for me.

    “looking very developer friendly” interesting point.
    Two sites running articles on it that I saw on the subject: http://www.gamesindustry.biz/articles/2013-02-15-playstation-4-must-demolish-the-walled-garden (you can also find a selection of development community blogs, and articles examining the PS4 reveal from that perspective, at gamasutra.com)

    “What Sony needs to do, rather than simply saying “yes we’ll support free-to-play”, is open up their business model and make it truly flexible. Put distribution and billing systems in place that allow developers to figure out the model that works best for them – whether that’s free-to-play, subscription, episodic, a $10 download or a $60 download. Take a cut of all the revenue that flows through the system, but otherwise step back and allow the negotiation on pricing and business model to be one between creators and consumers, not one imposed rigidly by a corporate behemoth in the middle of it all.”

    We didn’t quite see that, unfortunately. The way the speaker at the time spoke it seemed more to be hinted at, talk of Sony’s proven endorsement and support of indies, there was a passage afforded to “enabling new business models” and somesuch, but just a bit more there would have been huge.
    There was a mention by Mark Rein in the GT post-show of the UT3 mod cooking advantage that there was for PS3 players with PC (yes, he was shamelessly selling licenses on the Times Square set!)

    He did explain that The Samaritan tech demo previously released was created by Epic as a “love letter” to designers, and hinted that they received one answer from Sony which is why they presented the Elemental ++ demo, seen at the start of the conference.

    An interesting article on the subject of comparison: http://www.pcgamer.com/2013/02/21/pc-gamer-vs-playstation-4-theres-only-ever-going-to-be-one-winner-right/

    I do believe that comparing the console to the pc market is very relevant, especially after having read the first paragraph of the linked article. With ports from the console market to the pc becoming better, the question is whether the ps4 can contribute to the sense of gaming in a way the pc can’t, as, you can see in the article or discover for yourselves, a comparable pc-rig is both less expensive, and slightly more powerful. And this is just the beginning; currently you can get a strong computer the same money as the ps4 is likely going to cost, and the pc-hardware market is growing at an exponential rate.
    That said, I do believe I am going to own a ps4, but I don’t believe it’ll be able to compete performance/cost wise with the pc, and that without ever bringing up the high-end graphics crunchers of the pc. Read the article, you’ll see what I’m getting at.

    There’s no reason to talk about Nvidias Titan, because it could overpower a configuration of several ps4s combined. You don’t need that costly piece of equipment to make a pc that’s equivalent to or better than the ps4, and a pc can actually utilize the extra power that a supercomputer of sony’s machines couldn’t as they have graphicswise have a more adaptive platform. Games won’t become better looking for the ps4 until they make a ps5, whilst future games in the coming years until sony makes a new machine, will continue to utilize the constant evolution of technology. In two to three years time, the titan will be a fairly inexpensive high-mid end graphics card.
