GDDR has higher latency and much lower capacity. HBM requires an interposer and also has lower capacity. It's not an easy choice. The M7 family will probably double memory bandwidth using LPDDR6.

So the MacBooks might get roughly the M5 Ultra's bandwidth in a couple years. Not bad -- my M4 Max is currently stuck in 2016
