The lights are on
Following a story last week about the PlayStation 4's RAM profile, Sony has taken the opportunity to provide clarification. As you might recall, last week we shared a report that the PlayStation 4 held 3.5 GB of RAM for operating system functions, 1 GB of which would be available on a flexible basis for gaming. Sony has provided a correction.
In a statement issued to Eurogamer's Digital Foundry, Sony addresses a key technical matter from the original story.
We would like to clear up a misunderstanding regarding our "direct" and "flexible" memory systems. The article states that "flexible" memory is borrowed from the OS, and must be returned when requested - that's not actually the case.The actual true distinction is that:
We have no comment to make on the amount of memory reserved by the system or what it is used for.
This changes the outlook for development, possibly opening up significantly more available memory. The implication from Sony's comment is that the processes in place for handling virtual memory will be largely seamless and easy enough to use. The intent seems to be that regardless of the direct allocation, the flexible memory will be available for gaming.

Our TakeWe still don't know how much memory will be reserved for the system, and Sony's statement doesn't shed light on that yet. However, the process detailed in the statement made to Digital Foundry provides confidence that more than the 4.5 GB of direct memory and 1 GB of flexible memory will be accessible for game purposes.

It seemed odd that the report stated using he additional memory would be difficult for engineers when all that has been said about the PS4 by devs is it is easy to work with and develop for. I am glad sony decided to clarify the use of the additional memory and although it does look like the games will only be allowed to use 5.5 GB total (based on the statement choosing not to comment. I could be wrong) it is far and away more power than the PS3, not too mention e huge GPU that can handle a good chunk of lifting on its own and the better CPU will make the games look and run amazingly. Both consoles will look great so I am not worried about the power under the hood.
That's nice to know. Regardless about the 4.5 GB of RAM, that's still a lot of RAM for a console game, and like the article and Sony said, the flexible memory implies it will be more than that. Either way, no matter what system you get, games are going to look and play better than they ever have on consoles next-gen.
Well considering that at launch the ps3 took up 150mb of ram at launch and now only takes up about 50mb or so ram with optimization. I think given time Sony will optimize the OS to free up more ram for game use.
Very interesting how they didn't comment on how much RAM is used for the OS. Very interesting...
