Memory performance is asymmetrical – it’s not something we could have done with the PC. 10 gigabytes of physical memory [runs at] 560GB/s. We call this GPU optimal memory. Six gigabytes [runs at] 336GB/s. We call this standard memory. GPU optimal and standard offer identical performance for CPU audio and file IO. The only hardware component that sees a difference in the GPU.

我的理解，不分开，只是GPU优先访问更快的那部分，超过了还得到慢速部分来

: xb s x/s 的内存不是 cpu 和 gpu 分开的么，带宽也不一样
