Note that modern apple ram is not just soldered but actually in the SoC package. Sucks for upgradability, but that’s how they get 400Gb/s UMA speeds.

- wtallis 4y agoIn-package RAM vs soldered on the motherboard next to the SoC package makes no difference to the bandwidth: GPUs take the latter approach to achieve equal or higher bandwidth. In either case, having a memory bus wider than 128 bits is a major factor in offering higher bandwidth than mainstream platforms. (Wide memory buses are easier to lay out on a PCB when routing to BGA memory packages than [SO]DIMM slots.)
