So, now we know that LPDDR5 will be coming with at least 16GB per die stack. A doubling from LPDDR4. One package = 128 bit, a double of regular DIMM I/O width.
I see, it's not too much behind even HBM2, of which we may never see a mobile variant.
I was long pointing to people making laptops that LPDDR4 is much cheaper than DIMMs in overall, despite nominal per-GB cost being higher.
The elimination of manual assembly, termination, extra through hole parts, along with LPDDR actually taking less PCB area, less layers, and being less demanding of the PCB material easily compensates for higher chip cost.
