PlayStation 4 (codename Orbis) technical hardware investigation (news and rumours)

[chris1515]

My guess is 2gb

You're right the John Blow comments don't make sense, so throw it out and all the other ones and go with what is very clearly spelled out by ERP; none of the current statements on PS4 OS ram usage are correct.

Actually I didn't say that, all I said was I have yet to see a credible source quoted.
Almost everyone is speculating based on a rumor that it was 0.5MB when the machine only had 4MB.

This is the tech sub-forum. You need to elaborate.

Thanks for clearing that up. Speculating is what we do best!

Do you have insider knowledge of the RAM reserves for either consoles because i notice you didnt correct the xbone amounts? Or you just heard credible source for the 3GB?

He's a dev, so yes he does know. But he's smart and tied down by NDA so he won't stick his neck out and say anything unconfirmed because it will be his job on the line.

 

[Shifty Geezer]

He may not know about XB1, although there's nothing to be gained from coming on the board and stating he knows but isn't going to tell. Except the sadistic joy of tormenting the curious...

Actually DF said that, I quote:
"What we do know is that 512MB was the target during the time that PS4 was slated to ship with just 4GB of system RAM,"
Richard Leadbetter heard that the OS is at 1GB now but it's not confirmed as you said.

We IMO had a good discussion some weeks ago about the OS reservation but I think now we lack the necessary info to carry it further.

P.S.
Yoshida said that developers know about the actual OS reservation so all we need to do is kidnap a dev and ask him

1 or 2Gio for the OS.
I expect 2 Gio being slowly reduced during the console lifetime, just like it happened on the PS3, but Sony might surprise and use less from the beginning.

Someone should just ask Blow on twitter.

 

[Aeoniss]

Someone should just ask Blow on twitter.

He won't give a specific number, NDA's and all that.

Just ask can the witness use 6.99 GB of ram lol

 

[Gradthrawn]

Clearly he is talking about putting his whole game into ram.

Yes, exactly! He is talking about putting the whole game in memory. The whole game is over 5GB. The whole game "won't quite fit on PS4". I have no idea how we're coming to different conclusions. That's why I gave up. How someone can read that and then come to some other conclusion.

 

[Arwin]

Whole game currently uses over 5GB. That's a safe way of saying something but not revealing much. Also, that's the current game/current state, unfinished (but also unoptimised). So we don't know what he expects it to grow to.

Ram usage = game size? You are talking about two different things...

The over 5GB was ram usage.

 

[Gradthrawn]

The over 5GB was ram usage.

Yes, and the over 5 GB of RAM needed to not stream assets "won't quite fit" in PS4.

The Witness wants to use over 5GB right now, and that is by a small team. Textures + lightmaps + audio = lots of bytes.

Sadly, we have to deal with streaming. We won't quite fit on PS4, and we definitely won't fit on iOS.

The "wants to use over 5 GB' is in context of memory usage.

EDIT

I've been banging my head against the wall trying to figure out how we can both be using the exact same quotes and coming to different conclusions. It looks like I'm talking about his quotes entirely in the context of memory usage (which seems to be the context of that entire string of tweets). You're talking about 5 GB of memory usage, and then taking that second tweet of his as context about memory needed to load "the entire game" with that having some other, higher, memory requirement. If that's the case, I have no idea how you're coming to that conclusion and it seems like a leap in logic to me.

 

[Kb-Smoker]

You understand those tweets are talking about 2 different topics.

The first one is ram usage. The second one talking about loading the entire game into ram.

They have nothing to do with each other.

Ah, my suspicion was correct (just edited that when I saw your post). We'll have to agree to disagree, as in my opinion, in the context of those tweets, they have everything to do with each other and are the same exact topic. That seems obvious to me based on the context of all of those tweets being about memory usage, the pain of streaming large assets, and that he'll have to implement streaming because it won't in PS4 or IOS. Those seem quite logically connected. But that's fine, at least now I understand where you're coming from.

 

[Kb-Smoker]

Pretty big assumption that they are not streaming data into ram now....

 

[Gradthrawn]

Not really. That entire string of Tweets (before and after the ones I quoted) paints a pretty clear picture. Quoting them from Twitter would be a pain due to the way it orders things, and I'm too lazy to do so for this argument. But you can click on those links and follow the Tweets in order. But since I can't be arsed to back up my interpretation of his Tweets with supporting Tweets, I'll stop arguing.

Well 6.5GB is over 5GB, so is 7GB..............he doesn't give the exact game size, nor the exact memory available. Game could also be 5GB in size but require 6.5GB of memory.
