This is what mobile SoCs use. https://en.m.wikipedia.org/wiki/Package_on_a_package https://en.m.wikipedia.org/wiki/Package_on_a_package If trace length was a big factor surely PoP would offer even greater improvement. Anyway the point is, this is not a meaningful performance benefit as it's still just off the shelf LPDDR5. In fact the M SoCs tend to underperform in memory latency tests.
