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

No PS4 for me :/

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…

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

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…

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
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

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.

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.

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?

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.

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?

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.

@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 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.

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

@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.

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

@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.
