In a factory most likely tailored embedded systems are used, or special devices with PIC microcontrollers and something like this. A lot of code is still programmed in Assembler for perfect optimisation. Take a more educated realistically guess. 32 bit ports provide software such as Firefox, tools to program and compile etc., so the needed computational power using 32 bit CPUs, requires more power consumption, than using 64 bit CPUs.
