One of the big reasons the ps5 usually beats out the Xbox hardware, despite worse hardware by the numbers, is because of this kind of thinking.
They built a custom ssd controller that the gpu has direct access to. This means when something needs to happen involving the ssd and gpu, the gpu can just directly access the memory it needs to without needing to wait on the cpu.
Just let the gpu do what it does best without having to wait on the cpu, and everything is going to go so much smoother.
Isn't this how DMA works?
Eh in a way, dma is like the cpu offloading to another chip. What sony did is make the gpu not need the cpu to use dma
