你看看结构图就知道有多大差别了，ssd 读取的数据可以不经过操作系统和 cpu，直接到 GPU 里。而之前的架构里 CPU 用于数据读取和解压的开销很大，成为了瓶颈。
所以 PS5 的存储性能是革命性的，这就是我说的针对封闭生态里进行针对性的大幅优化。

Right now, CPU overhead from data decompression and management is pretty high. The more data that's moved, the more the CPU is taxed, and if it's pushed too far, frame rates drop astronomically. That's a big reason why Sony is optimizing data streaming on the system to ensure pipelines are flowing with enough speed and efficiency so that games look, feel, and run better than ever.

说起 unified memory，苹果真没必要说的有多么创新，2013 年上市的 ps4 就已经用上了

@felixcode
融合内存和显存

@clavichord93
unified ram 是融合内存和内存吧
我说的是显存能直接从 ssd 读取数据

部门交换机都使用不同的 ip 段后接入路由器，做静态路由
路由器端口多的话，同一交换机下再增加网段

没有砸场子，bsd 的确值得考虑，比起 Linux 来说碎片化的确没那么严重。

@yklaxds
谢谢！

@linux40
谢谢！

请教下，openbsd, freebsd, netbsd,dragonfly bsd 的主要特点是什么，有啥区别，怎么选？

@haiyang1992 多谢！

DirectStorage on PC: Gaming First
So far, Microsoft has only disclosed plans to bring its DirectStorage API to its Windows operating system as well as to provide it to game developers in 2021. This will essentially enable future PC games to take advantage of the same technologies as upcoming Xbox games will.

试过不同支付方式完全下不了单

果然够怂，2B

@clavichord93
睁大眼睛看看吧
The PlayStation 5 features 16GB of GDDR6 unified RAM with 448GB/sec memory bandwidth. This memory is synergized with the SSD on an architectural level and drastically boosts RAM efficiency. The memory is no longer "parking" data from an HDD; the SSD can deliver data right to the RAM almost instananeously.
你倒是用你的显卡从 SSD 上直接读取数据出来啊，或者你能耐在 PS5 上装个 Windows 出来啊
这不属于架构的变化？ M1 才能称的上架构是吗？

@Anhedonia
想骂人却不敢直截了当的指明是谁，这叫空气骂是吗？是不是很壮胆，哈哈哈

@icyalala
既然这么通用，你不用 XCode 能开发出来 MacOS app 和 iOS App 吗？用个别的 IDE 写代码再用开源的编译器编译就行了。
Office 在你看来很容易移植了，重新编译一下就行了啊。

@clavichord93
XBOX 不了解，PS5 的硬件已经和 PC 架构非常不一样了。
