A report was released today that details Playstation 4’s RAM usage when it comes to the OS, and how much is allocated for game development on the PS4.  This video highlights the latest claims coming out about the PS4.

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

Sony’s internal docs say that 4.5GB is the baseline amount of guaranteed memory available for game-makers  and most likely what the lion’s share of launch titles will be using. ~ Digital Foundry

 

For some context, the Xbox One devotes a comparable 3GB of its 8GB of RAM to the system software, according to reports, and the Wii U uses a full half of its 2GB of RAM for the OS. On PCs, Windows 8 needs 1GB of RAM ~ Arstechnica
