Sony Responds To PS4 RAM Allocation Rumor

Sony Responds To PS4 RAM Allocation Rumor

Has has responded to the Eurogamer rumor about the amount of RAM PS4 allocates for gaming which caused a stir on Friday, revealing that the machine actually has about 5.5GB of RAM for gaming purposes, and corrected a few “untruths” in the Eurogamer article.

Here’s the Sony statement:

“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:

  • “Direct Memory” is memory allocated under the traditional video game model, so the game controls all aspects of its allocation
  • “Flexible Memory” is memory managed by the PS4 OS on the game’s behalf, and allows games to use some very nice FreeBSD virtual memory functionality. However this memory is 100 per cent the game’s memory, and is never used by the OS, and as it is the game’s memory it should be easy for every developer to use it.”

Based on this new info from Sony, it seems that 4.5 GB of conventional RAM is available to developers, while another 1GB is also fully accessible, however it’s split in two: 512MB of on-chip RAM is used (the physical area) and another 512MB is “paged”. So all-in-all, PS4 allocates 5.5 GB of RAM for game development out of the 8GB, with 2.5 GB saved for OS functions.

That, to me, is enough. All games this gen, even the outstanding The Last of Us from Naughty Dog, only utilized PS3′s 513MB of RAM, which is half of 1GB.

No need to worry there, friends.
