这个@就是指访问某个范围时候速度嘛,肯定不能并发啊,以560GB/s速度访问10GB的时候剩下的6GB甚至不能访 ...
关键如果Eurogamer/DF转述XSX架构师有关XSX RAM分配信息无误的话,10GB/6GB不是一个整体……

In terms of how the memory is allocated, games get a total of 13.5GB in total, which encompasses all 10GB of GPU optimal memory and 3.5GB of standard memory. This leaves 2.5GB of GDDR6 memory from the slower pool for the operating system and the front-end shell. From Microsoft's perspective, it is still a unified memory system, even if performance can vary. "In conversations with developers, it's typically easy for games to more than fill up their standard memory quota with CPU, audio data, stack data, and executable data, script data, and developers like such a trade-off when it gives them more potential bandwidth," says Goossen. |
