PlayStation 4 – Expected 5 of the 8 GB

 

Sony’s PlayStation 4 is known to have 8 GB of unified memory. As is apparent from an internal document, probably 5 GB of them can be used by game developers. The remaining 3 GB is reserved for the operating system and other features and services.

The PlayStation 4 is known to have 8 GB of GDDR5 RAM Unified. Should also be clear that this may not be fully claimed by the respective games. Finally, things need as the operating system or other services and facilities, such as the automatic recording of the last 15 minutes of the game ( we reported ), random access memory.

But how much RAM is left for game developers, for now, they can really put on? By default, developers should probably calculate with 4.5 GB “memory direct”. Anyway, to this the “flexible memory” (presumably 1 GB of virtual address space, of the 512 MB of on-board chip RAM are used), which is managed by the operating system for the game and used about FreeBSD VM functions are can. Thus, the developer should ultimately 5GB RAM available with which they can work.

Conversely, of course, means that proud 3GB go to all the rest. In the past, once of 512 MB of RAM was the speech, but also only 4 GB of total memory at that time were provided. Moreover, at this point things should not have been already scheduled as the sharing function or the demo streaming.

The information here comes from an internal document of Sony, but were apparently previously interpreted something wrong. So were Richard Lead better of Digital Foundry first assume that developers default 4.5 GB RAM available, this still 1GB »flexible memory” is added, the diverted for given conditions of the operating system “could” – so all in all 4.5 “up to” 5.5 GB.

But a statement from Sony said now, however, that the amount of RAM is specified fix for games and not be dependent, among other things, an OS function. With a fixed predetermined limit to development work should be planned something better.
