Have faith and do the math.

1280 is only 5/4ths of a K, so each 8bpp eats 1.25 megs.

With 3-byte packed pixels they could get away with 4 megs.

6 megs probably means they are using 4-byte pixels (probably to provide
alpha or Z channel) which takes exactly 5 megs, leaving a whole meg of
offscreen memory to cache textures and other fun stuff.
