我搜了一下，以前应该是看的这个

The Xbox Series X allocates 10 GB of its memory for the GPU, 3.5GB for standard memory and 2.5GB is reserved for the operating system. The bandwidth for the 10 GB GDDR6 is 560 GB/s while for the remaining 6 GB it is 336 GB/s. The optimization for graphics memory is what makes the Xbox Series X fast.

到底啥样就只有微软知道了

【 在 Avocado (Persea) 的大作中提到: 】
: 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 a
: 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
