PS4 has 8 GB OF GDDR5 RAM

Mentioned by me volumetric effects (explosions, smoke) from Knack trailer.

Did they mention that all that 8gb ram is for games?

With that kind of social service running in the background and sharing thing how much will be left for gaming? 6gb?

This is one of the reasons why I'm not so excited about the 8GB of ram. A lot of it will be allocated to the social services and plus the OS that are running while you play. They need plenty of RAM for all this to run smoothly.

*edit: I'm seeing people say that they PS4 may have 7.5GB ram for games. That would be nice (and definitely a reason to be excited), but i'm pretty sure the OS is going to use a lot.
 
This is what the WiiU did and Iwata said that they are looking to reduce 1024MB OS footprint in half.

Source please? I had not heard them say this officially. Just that they were going to speed the OS up, not reduce its RAM footprint at the same time.
 
Assuming the rumour claiming the OS footprint is to be 512MB wasn't just hot air, I really don't see it blowing out by anything more than a further 512MB.
 
Personally, I'm really happy they've upped the RAM to 8Gb, so that MSFT couldn't say they have twice as much - the general public won't care about the bandwidth discussion as it's too esoteric and only understood (?) by enthusiasts. Too bad however that this move will most likely back fire in the price (or Sony's subsidy) of the console. Having said that, I feel it was a last minute decision (which some devs since confirmed) and was not backed-up by actual technical requirements, as general consensus was thus far that 4Gb of GDDR5 with much lower OS footprint and higher b/w will be enough. Hope that until launch they can somehow change that to stacked 8Gb of GDDR4, to retain the b/w and size, while reducing the cost (if that's possible).

Now, looking forward to see what they do about Durango's twice-as-powerfull CPU. A hint for Sony - go to 16 cores ;) :D
 
That looks good.

Speaking of Knack, the intro part that focused on the building didn't sit right with me. It looked like CG but a blurry kind of CG.

I downloaded original trailer from Gamersyde. IT is 1080p@30FPS. There are places in which AA brakes like Knack assemble part.

I think it looks so good (as CG) because actual characters are not crazy detailed same with rest of what you see thanks to their ART.
 
Just a week ago everyone was creaming over 4GB of RAM, but now that we have 8GB of RAM there is a lot of people coming from under the bridge to say it won't make it a difference, that it is a bad design decision?

As if you thought Shadow Fall looked great in its current form just imagine what upgrades its going to get just by optimizing the engine designed around 4GB and then modifying the engine to accommodate double the amount of vRAM!

This is going to be an interesting gen indeed.

"a lot of people" is a bit of a stretch, there's only been a couple in this thread.

I might be wrong, but the comments are not about size, but type of the RAM - it's great to have 8Gb, but it doesn't need to be GDDR5. Adding that is pointless when you're limited by the GPU. For example nVidia's Titan has 6Gb of GDDR5 and is like 6-8x more powerfull than PS4's GPU - if they felt it's better of with 8 or 10Gb they'd put it there, because at this price 100$ more is not an issue anymore :)

Durango has the same CPU as orbis ....

Someone, a lot more knowledgeable than the most of Gaf will have persuaded Sony the multi billion dollar investment will have been worth it.
 
What twice as powerful CPU?

Search the Durango vs. Orbis thread - it's been speculated that Durango's Jaguar cores are basically able to process two instructions in the same time when Orbis' CPU would do a single one, because of some bus/register expanded from 64bit to 128bit (take this last part with big grain of salt - I don't know what I'm talking about). The point of all this is however, that 2x faster CPU adds only 100 GFlops to the system, while Orbis' GPU is 600GFlos faster - but again, that's quite esoteric.

Okay. Thanks for the update.

And in terms of Orbis's GPU vs Durango. We don't know at this point if MS has improved on the leaked spec.

I would imagine there are folks in MS headquarters that shat their pants when they heard that PS4 would have 8Gb of GDDR5 memory and are currently scrambling to work out how to match that spec.
 
No, we really don't know about this. The PS4 OS was rumored to use 512MB of ram, and thus far no other rumor suggested otherwise.

Yes, that is the rumour so far. I am saying that increasing the overall RAM now gives them the opportunity to pad the OS with features (if necessary) to compete with XB3 when its OS features are revealed.

Zup bro. So what you're basically saying is they showcased the lowest possible "high end" tech demo on KZSF(if that makes any sense)? When they utilize more RAM they should be able to drastically improve on KZSF visuals right?

I'm really buzzed about the other titles they have under development for PS4 aswell, just imagine how the next Naugtydog games will look like or the next Santa Monica Studios games will look like. I mean Sucker Punch is an amazing studio and Second Son looked orgasmic and that was truly a nextgen game, but in my honest opinion both Naughtydog and Santa Monica Studios have outdone Sucker Punch interms of visuals in PS3 gen. So imagine how much better visually their games will be compared to the jawdroppingly gorgeous Infamous Second Son.

I am not sure about dramatic improvements (which will come gradually over the years) but it is very likely that KZSF was designed around older spec. Given the tremendous improvement we saw between KZ2 pre-alpha and final product, there is a lot of improvements to come (increase in RAM notwithstanding). And the RAM increase ought to improve certain things even further (frame rate not being one of them).

You can read this bit here (and click on the article for more info):



As the generation goes on a roll, the devs will start to utilize the hardware better and better which is agnostic of hardware design (hence the reason why first generation Xbox or Xbox 360 titles look so very out dated compared to their mid-twilight year releases).

At the hands of talented developers, I am sure it will shine. The good thing is that struggling to learn the system has been seemingly removed from the equation. Now it's
 
Some more volumetric smoke from Knack:

ibvU6EeXzYe1ZP.gif

Yeah, same as above - I'll believe it's truly volumetric when Knack walks through it and smoke ebbs & flows naturally through elements of his body (which, BTW are the most impressive thing in this whole demo, as they seem to be 'physically' connected to each other and moving accordingly to Knack's actions)
 
Nice, but where you see "volumetric" here? The smoke/fire/particles do not interact with geometry, so those might as well be 2D sprites...

Look at left down corner and look how explosion behave. Mind you it is trailer we don't know if it is prerecorded but volumetric fog isn't newest hot thing. It was in Stalker kind of 2009. It is noticeable jump because PS3 or X360 simply didn't have bandwidth and size to do them.

EDIT:

Volumetric doesn't mean that it needs to react to physical contact.

On other hand i remember some games that did volumatric effects on consoles.

Pro drift which had volumetric smoke from tires (for burnouts) which was affected by physics
Uncharted 2 grenade explosions which were static
 
"a lot of people" is a bit of a stretch, there's only been a couple in this thread.

A lot of people isn't specific enough to make that kind of inference =p

It's been going on in every thread I've been frequenting. For every three posts of enthusiastic posters there is always one that is like "meh" when my point of view is hey a week ago we all accepted 4GB of GDDR5 but we know have double that, let's rejoice!

8GB of vRAM is fantastic no matter which way you look at it and the developers are happy about the design choice as well. That makes me happy knowing they are ecstatic to start pushing the boundaries yet again. Shadow Fall hasn't even begun to push the boundaries either, I believe. Remember the leaps they made from alpha to final production? Same thing is going to happen here, albeit with perhaps a frame rate boost because of the RAM increase?

I'm excited.
 
Even if it's only 7Gb. It's still massive.

Even at 5.5-6GB that statement still stands. Plus, we have yet to learn whether would be some form of partial OS offloading to the rumoured 16GB flash chip (designed to store updates even during low powered states) or that in time, like the PS3, the footprint would be eventually reduced.

It's a long road ahead.

Knack is really flying under the radar. I thought it looked great.

I think it has to do with the artstyle.
 
Here's a question. Let's say MS announces 8gb of 3 RAM. Sony has 8gb of 5 RAM.

What exactly does this mean for games? If Call of Duty 20 was made for each system in 2014, what kind of graphical differences would there be?
 
Wait didn't they show footage of Knack running on Vita or was that a different game? I was extremely impressed by the trailer when I thought it was real time but the gameplay looked completely different.

A smoke being "volumetric" or not has nothing to do with bandwidth - you need bandwidth for overdraw, i.e. how much transparent things you can put on screen at one time (and this is where PS2 & X360 where much better than PS3). Volumetric means that the smoke (or fire, water, etc.) are not just sprites, but are "conscious" about the geometry & conditions of the scene (e.g. wind) and - being split in mutitude of particles - interact with it, i.e. smoke is moved by wind, by passing objects, flows through scenery (e.g. gaps in stairs). This requires strong CPU or - even better - a GPGPU, because it can be highly parallelised. And this is why PS4's extra 6 Compute Units (18 vs. 12 in Durango) is - might be, it's still uncertain - such a big advantage.

We just don't know a whole lot about it. The fact that Cerny has been working on it says that it will probably end up being a bigger deal than we've made it out to be so far though.

it has a lot of fun gameplay potential, Knack can changes to multiple forms, each can come with it's own unique ability, shrinking to small form can allow him access through vent or small hole, he can also change material like in the trailer he become glass material to bypass laser sensor.

it's definitely on my radar as games to watch, and I've just watch Mark Cerny 1 hour Q&A from Nov 2012 and he sounds like he really understand game design and what make a game great.

Frankly i don't think we are people who are be playing this game. I think it is created mainly with kids in mind same as was Crash or Spyro. It is directed by dude which was responsible for crash spyro and a lot of sonics past 1st one.

When you look at Knack and artstyle it is imo created with kids in mind. For example this character could be in any pixar film (from design not GFX side):

Yeah, you're wrong. It needs to be GDDR5. Lesser GPUs than the one in the PS4 still use GDDR5 - in fact, if you're buying any graphics card at all you shouldn't buy one without it, because that means the manufacturer doesn't give a fuck about the performance. Now if you're making a console and doing some custom shit like Microsoft you have options, but if you're just going to stick some chips on there and call it a day it should be fast RAM.
