The PlayStation 4 will ship with a massive 8 GB of GDDR5 memory, which is a huge upgrade compared to the current generation consoles. However, according to a PlayStation 4 developer PS4Daily spoke to, they have access to “only” 7 GB of RAM. The remaining 1 GB is reserved for the operating system and background tasks.

Sony showcased a lot of PlayStation 4 features during the unveiling in February. This includes deep social features running in the background, new sharing options where players can watch each other play, and background downloading of games. All this chews up quite a bit of memory. Still, having access to 7 GB of super-fast GDDR5 memory is a lot better than the 512 MB in the PS3.

Sony originally shipped dev kits to third party developers with only 4 GB RAM, and kept the true RAM amount secret from third party developers in order to keep it secret from Microsoft as well. Developers learned about the 8 GB of memory when the rest of the world did — during the February unveiling.

In addition to 8 GB of RAM, the PlayStation 4 sports an 8 core CPU and a GPU with 18 compute units, both part of the same APU package made by AMD. Sony worked close with developers to give them a console that’s tailored for games. Sony interviewed major game engine makers such as Epic (Unreal Engine 4), CryTek (CryEngine 3), and Id Software (Id Tech 5), asking them what they wanted out of next generation consoles. Overall, Sony worked closely with developers to create a console that made it easy to create games.

When it comes to large operating systems taking up a lot of RAM, Sony isn’t alone. Nintendo did something similar with the Wii U. The Wii U ships with 2 GB or RAM, but half of it — 1 GB — is allocated to the operating system itself. As console makers add more and more features, they need more and more memory to run those features. Microsoft is even rumored to include advanced DVR functionality in the upcoming Xbox 720, which will no doubt require copious amounts of RAM.

Sony is expected to reveal more PlayStation 4 details at E3 in June. We’re also hearing that this is when some of the NDAs will be lifted, where developers will be more free to talk about the specifics of the new console.


PS：以后PS4游戏移植到PC平台怎么搞？7GB-->2GB??另外之前说的Video Capture功能看来也不需要占用太多的显存？

更新：A9有液内爆尿说实际游戏可用是5GB，CPU8核心有6个是游戏专用

操作系统要3GB是不是太大了点

孤岛2显存利用最多2G多一点 足够用了
显存大最适合开放式游戏 GTA6绝对大到难以想象

肯定不会那么大 你的思考的范围太窄了
反正系统游戏专用 最少2.5GB的多任务空间 也许以后会和IOS游戏一样 多游戏后台运行

太良心了。ps4的潜力很大啊。

所以不升级到8g，只要1g给游戏，sony必须死啊

初期肯定很多游戏应用不到多核心和大内存，会有玩家抱怨浪费配置索尼无脑

看上去很牛叉的样子，实际撒样鬼知道，大部分跨平台的，加上成本因素，日呆拖后腿什么的。

就PS4系统而言，又不是桌面操作系统，需要运行那么多乱七八糟的进程，1G内存足矣。

估计也就一两个独占游戏发挥一下。

听起来牛逼，实际上一定sb死了。索尼从来没让我失望过

考虑到ps4的一大堆社交功能，2gb内存还真不算多

社交功能？核心不是游戏吗？
