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.
