Forums - Sony - PlayStation 4 gives up to 5.5GB of RAM to game developers

But seriously, I wonder what they are doing with such a large OS? I doesn't have a Kinect running and voice sampling going all the time. So what could they be doing?

The new Kinect has it own hardware, so theorically it should'nt use so much resources from OS or RAM.

Well I am going to take the word that Richard read Sony docs on the case. The document says developers have a guaranteed 4.5GB.  This was not disputed by Sony or anybody else.  Anything after that was part of the flexible memory.  How that flexible memory is to be used really isn't that big of a deal because it was not part of the direct memory.   Developers can depend on only having 4.5GB at any given point in time, thats what guaranteed means.  After that, they can use addtional memory but I am sure those are based on scenerios if the memory is available.  ALso within the EG article Richard never said this stuff was written in stone but and could be changed by Sony as things mature on the system.  There is nothing fundametally false about the article and based on his sources he clarified the parts that needed more understanding.  If the document is outdated then why would Sony have developers with outdated documents about their system.  You say you trust developers but there is nothing to say that the same sources DF is using is more rep than Gaf.

Last but not least, you are basing your opinion on unknown sources against another person unknown sources.  Difference is that the person doing the article is not unknown and I am sure he trust his sources.  So yeah, I would put more stock on a person willing to put their face and name on the line then someone jumping into a forum, who no one has a clue who that person is or their agenda saying something is false or that some game somewhere is doing this or that when they cannot even name it.

There's a big difference between claiming you are an insider on VGC and claiming it on GAF.  Here, you claim whatever you like and only forum posters will call you out.  On GAF, you have to prove to the mods that you actually are an insider, otherwise your ass gets banned.  Personally, I put more trust on the insiders on GAF, who's track records can be proven, than the truly faceless resources that Leadbetter says he has, who's track record we can NEVER know.  Of course, there also the fact that Leadbetter has posted 2 false articles about the PS4, which shows it in a less favorable light, and 1 false One article, which shows it in a favorable light, in the past few weeks.  Something tells me he and/or his sources have an agenda.



Yikes, GAF's reaction to this has been too fucking adorable. Expected, but still adorable.



So to sum up, we dont yet know if any of this is rumour or fact yet.

Should it prove to be true, the vast majority of PS4 developers will have access to less RAM than Xbox One developers, though this will be tempered to some extent, depending on game type, by the types of RAM in play.

Maybe the 6GB it true, but some of these insiders were banned a few times for being way off.

Seriously, in what world is it normal for an OS to use nearly 4GB? Is it the live video capture or...?

I already thought that this feature that lets you share streams even from some time ago of your gameplay must be a hard hit on memory, but I thought probably Sony reserved enough harddisk to save it there. Seems it is more used for memory. Maybe the sharing-feature is deactivated or restricted if the game uses the extra gig.

Well 77GB is reserved on the HDD (423GB available to users) but I'm not tech savy enough to know what it all means.Again, we should hopefully get answers at GDC.

It is not 77GB reserved...

The HDD manufacturers uses the 1000 notation to calc the size of HDD and not 1024 (the right)... so a 500GB HDD have 500,000,000,000 bytes and not 536,870,912,000 bytes.

If you convert to standard notation (1024) you have: 465.66 gigabytes

So 423GB available to users means 42GB reserved.



(Documentation for the feature Sony referenced in its clarification - http://www.freebsd.org/doc/en/books/arch-handbook/vm.html )

Lets be honest. Sony could make this whole discussion go away quickly by saying, the OS uses 2GBs and games have 6GBs, but they haven't. They told Eurogamer, your terms are wrong. Sony hasn't attempted to offer correct numbers. What they did was clarify that there wasn't 1GB in play, therefore a set amount for the OS and a set amount for games, but games also had virtualized memory in the form of a disk cache.

An anonymous, non-credible, unverifiable source on GAF is not Sony responding. Sony has back channels, that are credible and verifiable that could respond to this article. They haven't. Sony is silent, their back channel sources are quite.

I don't get what is so bad about this that Sony just can't offer a quick, concise clarification to make this conversation go away. Seems perfectly reasonable to me.
