Modern AMD64 CPUs only have around 48 address lines, but we don't describe them as 48 bit. Registers and pointers are 32 bit, too.

  Likewise, the 6502 and Z80 had 16 address lines, but we never describe them as 16-bit.

    Right, it is generally about the ALU. It is hard to give registers too much weight, because both Moto designs used large registers.
