Why Apple packs something like 64 Gb on the CPU chip and NVIDIA cannot?

Apple uses LPDDR4 which comes in densities of up to 16Gb AFAICT. So they can have ~5X as much memory using the same bus width.

Apple uses LPDDR5X, not LPDDR4, iirc

Of course it's ddr5 not 4.

From PCB perspective, LPDDR5(X) interface is quite different from regular DDR5. Same with DDR4 and LPDDR4. Source: have designed few boards with different memory interfaces.

LPDDR dies can stack but GDDR cannot?
