It's still one or more PCBs, a battery, the LCD, the microphones, the microcontroller and the small components on the board. The capacity of the chip is besides the point. Each one of those components has a very deep production chain and cost a lot of resources to produce. ICs are created through chemical processes that use a bunch of substances that are themselves not manufactured, for example. The bottom line is, those electronics are wasteful.
