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.”

@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
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 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
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

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.

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

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.

@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.

@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.

@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…

@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.

“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.

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.

My iPad has more RAM than 360 – see what I did here?

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.
