The Game stack presentation showed some intriguing information about XSX RAM usage.
The presenter explains that all 6 GB of slower ram (at 336 GB/s) is reserved for the OS. And only the 10 GB of the higher speed ram (560 GB/s) is reserved for games. Earlier, at the time of launch, it was marketed that only 2.5 GB of the slower 6 GB ram was reserved for OS.
This distinction is also visible in the presentation slide, where the slower ram at 336 GB/s is termed as Operating System Memory, while the faster 560 GB/s memory is called as Game Title Memory.
It kinda feels like Xbox like to shoot themselves in the foot when it comes to hardware sometimes. Also, what would this mean for XSS?
Edit: it turns out it was a mistake with the presentation.
I think you have misinterpreted what he means. Microsoft described the 10GB to DF as game optimal memory and that developers should use this for their more bandwidth intensive game code and the other 3.5GB for other things like audio etc.
So in summary, no the XSX doesnât have âonlyâ 10GB for games and it is still the case that the OS takes 2.5GB. If you need more convincing then consider the OS is exactly the same as the Xbox One and that doesnât take 6GB and for that matter what does the Series S have? Like 2GB for games or at most 3 lol.
A full version of windows doesnât even use 6GB on my Surface Pro 4 so goodness knows why you would need 6GB for a games console. I would also add that if Microsoft did want to use 6GB just for the OS they would have used much, much slower RAM like they did with the Series S, which is 2GB by the way and ties into the 2.5GB being reserved for the Series X.
Like I said, terms and meanings have likely been crossed here and nothing has been heard from developers about any RAM changes, the only thing we have heard is some rumblings about the Series Sâs RAM amount and that is it. I honestly would not worry about the slide.
To be fair, this did come from a Microsoft employee so it was not a rumour or anything. However, people make mistakes and yes, some digging would have told you that it was indeed a mistake.
Yes it was a shameful mistake for an employee to make but itâs not like they hadnât already divulged (several times already) that the OS takes 2.5GB of RAM. And when you consider that the Series S has a total of 10GB of RAM then it should have been obvious that something was not right.
