Hmm, no, not at all.
With a VGA device in text mode, screen memory is one byte per
character, no pixels,
so writing 20x5 characters is writing 20x5 bytes into screen memory.
The hardware handles turning the character memory into streams of
pixels to the VGA connector,
each character's pixel matrix provided by e.g. the cape's hardware.
