Your link is no confirmation, it especially uses "rumor". Please be more reasonable, ethomaz. Don't exaggerate where it is not needed. Also ram-usage is always subject to change as we know from this generation. You should know this.

WTF? You watched the interview? lol lol lol

Confirmed by Whitten.

And reasonable? People are saying that RAM will change between the OS App and OS Games... so if I have dozem apps installeds I will have issues in the games because the OS App is using the RAM that was to be used for OS Games???

I'm the only reasonable here lol

No need to "WTF lol lol lol"....

The interview do not say the 5GB will be STATIC in any way. You are making that up and no, you are not reasonable... As always with Microsoft's rumors/speculations... And your exemple is plain stupid (the exemple, not you before to you report me for that), applications can easily swat memory context (like any mobile device today AND there will certainly be a limit to the amount of memory an app can use... 

Even if the maximum amount of memory for games is 5GB, nobody from Microsoft confirmed it would not be possible to dynamicaly allocated less (or more for the apps)... This is just speculations from you. And being based on Hyper-V; with this feature being build-in, I do not see why it seems "unreasonable" to believe it will dynamic...

The size is close to that... the guy confirmed... can be 6GB for games but that doesn't matter.

What I'm saying is that the memory for games can't be dynamic... the dev can use only 3GB? Yes, it can but the system will reserve xGB for games even if you less... if the OS App is not using RAM the OS Games will not get that RAM for it.

You can't says to devs... you have 5GB RAM reserved and at the end the system changed this amount to 4.5GB because the App OS are using more RAM... or if you said to devs that 5GB are reserved to Games and the OS Games take more 1GB for it dynamically that won't change nothing because the game was made using 5GB.

You guys can't be serious when says that the OS App and OS Games will reserve dynamically the RAM via hyper V... that's makes no sense.

I'm being reasonable here.

Xbone will have reserved to OS Games (and no other OS can touch that): 6x CPU cores, ~5GB RAM and 11 GPU CUs (~90%).

PS. Every site, every one... says that MS confirmed the 5GB RAM reserved to Games... they use that word "confirmed".



Uses too much RAM right now, they should of just kept it simple on the system's resources. So it could do more with games. Looks clean though albeit nearly looks the same as the current Xbox 360 dashboard. I wouldn't use the snap feature but i'm sure some people would enjoy it.



Xbox Series, PS5 and Switch (+ Many Retro Consoles)

Prediction: Switch 2 will outsell the PS5 by 2030

you must have a load of apps to eat up more than 3GB in apps on a console.... I'm not even sure if you open all the apps on the XB1 at the same time it could be achievable.....



Just like someone stated, I remember reading an article that said games could use up to 7GB of RAM if needed. I'll try to find the article.

yeah they locked 5gb for games it doesn't mean they won't free up more dynamically with hyper V just to give more leeway to games to maintain a more stable 60fps.... I don't see the point of locking 3GB for apps on the other hand... so yes they might have locked 5gb for games and all you said on that side.... it doesn't mean they locked it up on the other side for apps though.... I have an old win 8 pro tablet with 4Gb in ram and I have never had issues with win8 apps being open in the background and a lot of them so I doubt the 5 apps that people might have on rare occasion running at the same time on a Xb1 will use up that much RAM.... but I might be wrong....

@superman4 1gb of RAM is the min requirements and only supports 4gb of RAM. the 64 bit version requires a min of 2gb of RAM and supports 512 / 128 gb of ram depending on pro/stdrd version.

I'd like to say the main os would be closer to the 64bit version since win 8 is optimized for smaller devices in mind, and x1 would require higher graphical integrity, but will have (hopefully) less things running at once requiring less ram.

So I'd speculate the main os would require about 1.5gb of ram with potentially locking out the other 1.5 gb to do the snapping between operations and keep games running smoothly.

Microsoft has confimed that the Xbox One is 64 bit only.  The same thing annouced they were doing with the future Window 9.



 

Really not sure I see any point of Consol over PC's since Kinect, Wii and other alternative ways to play have been abandoned.

Tell me a funny joke!

MS itself confirmed.

"It has been rumored for months now that the OS for the new Xbox would use 3GB RAM and Whitten confirmed in this interview that it will require “around” 3GB. So it could be a bit more, could be a little bit less. This leaves about 5GB RAM for game developers."

http://gimmegimmegames.com/2013/05/microsoft-confirms-xbox-one-os-uses-3gb-ram-5gb-ram-for-games/

There are a link to the Game Informe video interview.

You can't make the resources for games dynimic... you want just kill a console gamers experience is you do that.


that article says "A lot of people have been questioning whether Marc Whitten not outright denying things like 5GB RAM is really “confirming” indirectly"  

lol ironically in microsoft world all rumors are true.  the sad part about that people can make stuff up and the internet will just run with it as fact these days

The article goes on to suggest it has been confirmed by developers.

Anyway, it wouldn't surprise me if it is true. Microsoft wanted a multimedia device so they've likely reserved a big chunk of RAM for OS, apps and multimedia. I expect that footprint to reduce and developers given more RAM to work with as the generation proceeds due to MS optimising the multimedia features.



well it still doesn't confirm anything though.... 5GB can be the minimum cap.... the bare minimum game devs will have to work with no matter what.... doesn't mean they can't tap into more if needed.... especially if since I doubt even with a couple apps open like Skype and NFL fantasy league you'll be eating up 3GB

but anyways 5GB to start with is a huge chunk of RAM to work with for VG on consoles..... and as said before even if this is the starting static cap you more than likely will see improvement along the lifespan of the console....



So they designed it like a virtual machine host.. that means, each OS running on it will have a static pool of resources to use.
With the info above the Apps-virtual machine will have 10% of the available compute power and the games VM will have the rest.
If it truly is a hyper visor a memory footprint of 1GB is quite absurd.
(if they aren't running like a core-install of MS hyper-V or something = server with no gui)

So.. hyper-visor 1GB of RAM, App VM 1GB, and the games VM uses 1 for the OS and then the games themselves can use the rest? plausible atleast.
kind of a 'weird' setup since nothing has direct access to the hardware, you create a-lot of overhead computing that will make it less fast than it could have been (if it was running directly on the hardware)
