There are non power of two sized DRAM dies in production these days; it's not purely a matter of stacking (and stacking doesn't make it any easier to have something in between one die per channel and two dies per channel). You can get 24GB single-rank and 48GB dual-rank DDR5 UDIMMs compared to a year ago when the options were 16GB and 32GB; no stacking at all, just going from 16Gbit to 24Gbit per die. But LPDDR has been doing this for longer due to demand in the smartphone market.
