PS4 Reserves 4.5GB RAM to Games, 1GB Flexible, Rest to OS – Report

ps4 featured 1

Sony has allocated 4.5GB of GDDR5 RAM to games, according to a new report on Eurogamer. It states that out of the 8GB GDDR5 RAM the system posseses, 4.5GB RAM is reserved for games, and 1GB is flexible memory which can be assigned to the games or the operating system.

So basically 3.5GB RAM is being assigned for things that are not games.

“PlayStation 4 reserves 3.5GB of its 8GB GDDR5 memory for the operating system, leaving 4.5GB of space for game code, according to current PlayStation 4 documentation shown to Digital Foundry by a well-placed development source,” the site wrote.

“However, further sources suggest that an additional 1GB of “flexible memory” may be reclaimed from the OS reservation, based on availability.”

This would mean the RAM allocation to the OS is the same as the one in the Xbox One, and that would nullify the advantage Sony has over Microsoft when it comes to RAM. The thing to note here is that the PS4 RAM is faster than the Xbox One RAM, but has a bit more latency.

Mark Cerny, lead architect of the PS4, had earlier revealed that the PS4 GDDR5 RAM latency wasn’t an issue.

    i’ve seen many people go nuts because of this RUMOR i find it crazy that they dont know the difference between GDDR5>DDR3 seeing as even 2GB of GDDR5 is greater then 5GB OF DDR3

    I doubt any of this is even true until sony confirms this which they haven’t because normally this type of stuff is speculation and if it is confirmed GDDR5 at any amount of GB is still larger then DDR3

      This is really stupid, you are not counting the eSRAM, it is fast ram (and DF said 190GB/s, faster than GDDR5) and can be used for graphics (as vram).
