On PCs some other hardware (notably the SSD) comes with its own memory. But here it's shared with the main DRAM too.

This is not necessarily a performance improvement, it can avoid copies but also means less is available to the CPU.

DRAM-less NVMe (utilizing HMB) is also common on PCs, but it's seen as a slower budget alternative rather than a good thing.
