The most crtitical ressources for performance is memory writes bandwidth.
packing 5:6:5 or 8:8:8 is mostly same overhead with assembly.

I remember an intel performance hint for reducing memory writes. to set a boolan to true check the value before writing.

so:

if (boolVal == false) boolVal = true;

is faster than setting value directly:

boolVal = True;
