The PlayStation 4 will ship with a massive 8 GB of GDDR5 memory, which is a huge upgrade compared to the current generation consoles. However, according to a PlayStation 4 developer PS4Daily spoke to, they have access to “only” 7 GB of RAM. The remaining 1 GB is reserved for the operating system and background tasks.

Sony showcased a lot of PlayStation 4 features during the unveiling in February. This includes deep social features running in the background, new sharing options where players can watch each other play, and background downloading of games. All this chews up quite a bit of memory. Still, having access to 7 GB of super-fast GDDR5 memory is a lot better than the 512 MB in the PS3.


Sony originally shipped dev kits to third party developers with only 4 GB RAM, and You must login or register to view this content. from third party developers in order to keep it secret from Microsoft as well. Developers learned about the 8 GB of memory when the rest of the world did — during the February unveiling.


In addition to 8 GB of RAM, the PlayStation 4 sports an 8 core CPU and a GPU with 18 compute units, both part of the same APU package You must login or register to view this content.. Sony worked close with developers to give them a console that’s tailored for games. Sony interviewed major game engine makers such as Epic (Unreal Engine 4), CryTek (CryEngine 3), and Id Software (Id Tech 5), asking them what they wanted out of next generation consoles.

When it comes to large operating systems taking up a lot of RAM, Sony isn’t alone. Nintendo did something similar with the Wii U. The Wii U ships with 2 GB or RAM, but half of it — 1 GB — is allocated to the operating system itself. As console makers add more and more features, they need more and more memory to run those features. Microsoft is even rumored to include advanced DVR functionality in the upcoming Xbox 720, which will no doubt require copious amounts of RAM.


Sony is expected to reveal more PlayStation 4 details at E3 in June. We’re also hearing that this is when some of the NDAs will be lifted, where developers will be more free to talk about the specifics of the new console.

I can't help but say "Duh!" The system is built on x86 architecture which only support a theoretical 4GB to be used so my general guess is as follows...

1GB = OS/System
2-3GB = Main GPU
1-2GB = APU's GPU
2-3GB = Processing calculations

These can vary between games and developers usage needed. Just my 2 cents! ^^

Last of us on ps3 already looks stunning, Im curious what sony has to offer at the end of the ps4 life cycle

im sure itll be great! look at the difference between games from release of ps3 to now. huge difference

thats so true, hopfully developers will bring the vita to live. I mean games like guacamelee are so great! they need to release a new god of war spin off and rockstar need to bring a new installment to the tabe

woooow that's crazy !!!!

Anybody with half a brain could have told you this. Just like the PS3 RAM is cut up into two pieces.
256Mb for the GPU
256Mb for the CPU

anyone would have thought your aiming that at me asif i wrote the article.

8gb of graphics memory i 100000% doubt this because a $1000 graphics card only has 6 at most and a os will run like shit on gddr5 ram

It's x86-x64 :p
