Ok, there're three different sets of bits you're looking at.
Original VGA was 640x480x16 or 320x200x256, the latter being 8 bit color.
Modern accelerated video cards are essentially computers, the fastest having
128 bit internal busses.
VGA cards did exist that plugged into 8 bit ISA slots (and indeed, 8 bit
apple 2 slots) but they were fairly scarce, because as you said, they came
out after 16 bit ISA.
