The first 256-bit graphics architecture is for Matrox G400 but it not real 256 bit architecture but casuse they use daul bus 128x2 =256
I don't know this much.Onemore thing I can say about this is whatever you use resolution and colors you will got same speed in Desktop.
But the first real 256-bit graphics architecture is GeForce256 (I don't know about MX maybe they use 128 bit).I think 256-bit graphics architecture is wider pipe and can send data faster than 128 bit.That is all I know
