Ps3 OS minnebruk

[UrgeLoL]

Med så mye rykter om hva ps3 sitt os bruker av minne kan det være greit å opplyse folk om hva som faktisk er riktig.

 

PS3 Memory Footprint

 

The release of the 1.60 firmware six weeks ago was recently followed by the release to developers of the corresponding 1.60 SDK. The SDKs always come out a few days after the firmware so that Sony can iron out any bugs, issues and complete the documentation for the new and changed features.

 

Ozymandias recently did an comparison between the 360 and the PS3, and their memory footprints. Some of the numbers used for the PS3 are slightly out of date, and thanks to this release, we have obtained access to the latest memory footprint of the various key system utilities.

 

First, the base memory footprint of the PS3 OS in main memory has been reduced from 56 MB to 52 MB. These values will lead to some confusion, as we’ve previously reported that the memory footprint was 64 MB. 8MB of memory was given back to developers sometime before Christmas, and now a further 4 MB has been returned. Currently, as of SDK 1.60, the PS3 operating system takes up 52 MB of main memory and 32 MB of graphics memory (84 MB total). As a comparison, the Xbox 360 still only uses 32 MB of shared memory for all its system utilities.

 

We have also learned that processing-wise, games are expected to maintain at least 30 frames per second, regardless of how much CPU time is used by the OS. Specifically, there is a Sony technical requirement that states that titles cannot rely on the CPU processing speed. There is no explicit ceiling set on how much processing time the OS can use through its higher priority threads. Of course, Sony will make sure whatever is performed in the background will have very minimal impact on processing time, but the lack of an explicit cap concerns us.

Syns det er litt rart at de må bruke så mye. :/ Burde nesten hatt en egen brikke på 64 mb i tillegg til OS.

Jeg syns det er pussig i at en maskin til 6000 så har de vært gjerrige med RAM.
