PS5规格初步技术分析 GPU频率严重虚标

不知道lz對此有什麼看法 我倒是挺好奇未來的遊戲設計

What John is saying sounds pretty right to me! I don't want to down play GPU power, but I promise everybody that you will be absolutely blown away by visuals on both consoles. However, the SSDs are the big difference when coming into this gen. We're not talking about "load times" in the classic sense. That's an antiquated way of thinking about data coming from your hard drive. For the last 10+ years we've been streaming worlds on the fly. The problem is that our assets are absolutely huge now, as are our draw distances, and our hard drives can't keep up. It means that as you move through the world we're trying to detect and even predict what assets need loading. Tons of constraints get put into place due to this streaming speed.

An ultra fast drive like the one in PS5 means you could be load in the highest level LOD asset for your models way further than you could before and make worlds any way you want without worry of it streaming in fast enough. The PS5 drive is so fast I imagine you could load up entire neighborhoods in a city with all of their maps at super high resolution in a blink of an eye. It's exciting. People don't realize that this will also affect visuals in a big way. If we can stream in bigger worlds and stream in the highest detail texture maps available, it will just look so much better.

I think the Xbox drive is also good! The PS5 drive is just "dream level" architecture though.

I can't speak for anybody else, but this is the exact kind of architecture I was saying would truly satisfy me. If someone came to me and asked if I wanted to give up a bit of pixel-pushing for the fastest drive I would take it without hesitation.

In my opinion, ultra fast drive speeds like the PS5 one are the true generational game changing technology. Series X is pretty good as well. However, the PS5 one is like a dream come true and I can't wait to see how it translates to everything from game design to lightning fast OS features.

还独占 你觉得PS5首发的时候能出几个独占
过两年再给你跨个PC 还觉得你平台玩家不友善
索尼最近是 ...

xbox直接登陆pc是不是可以直接不用买了？等都不用等

总之非常失望的一次这代本来就应该用一体式水冷 性能推上去就好

其实可能是用类似std的方式 将内存数据整个保存在ssd 然后切换或者启动的时候 直接从ssd读取连续数据到内存 就不用这取一点那取一点 速度起不来

lod基本还是gpu问题 游戏开发者控制 和ssd关系不算太大

大法烂牌啊 要凉...当然如果价格优势的话还是可以

用一体式水冷故障率会高很多 特别是2-3年后 对于个人用户不能维护的大批量出货的工业产品这是不可以接受的

没什么好失望的，玩游戏又不是玩机器，玩机器树莓派是更好的选择。

关于SSD的大文件持续传输速度和4K性能的区别，别被PC上的SSD固定思维给限定了了。
无论PS5还是XSX都强调了压缩数据的等效传输率，这说明了一个问题：PS5和XSX的开发套件都支持把游戏同一场景的数据在游戏分发打包时打包成单个大容量文件，游戏加载时从SSD高速读取并通过专用处理器解压缩到系统运行存储器中(结合最近的新闻这个功能两个平台都是独立处理器完成而不需要CPU参与)。

现在主机是源自PC架构，但是很多设计思路都是不一样的，例如同一内存架构(PC游戏性能的瓶颈在主RAM到GRAM之间的数据拷贝)。

你这个也是说不通的 大多数pc AAA游戏数据也封装成大文件 但实际读取的时候 还是在封装里选择性的读取 而不是读取整个文件 我nvme ssd 读游戏 基本也就顶头300mb/s水平。

但我上面还有个猜想 可以看看上面几楼我的回复。

论首发兼容我觉得PS5简直躺赢了，一上来就能玩强化版神海，战神，血源，蜘蛛侠，最后生还者2这种，读盘还 ...

你错了，ps5兼容的很不好，被大家都骂死了，只兼容ps4部分游戏，通过模拟ps4实现，不会比ps4pro加强什么。
