Think about it like this... In 1-bit dithered scheme, 1 machine word represents 64 entire pixels worth of values. You can access 64 pixels at a time and use bit-wise operations to manipulate the individual values. Compare to a typical 24-bit RGB array, you just reduced your full-scan array access requirements from 3 per pixel to 1/64 per pixel. For 720p (1280x720), you'd only be talking about 14,400 loop iterations to walk the entire frame buffer. You could almost get away without even compressing the frames in some applications. At 30fps, totally uncompressed, 720p 1-bit dither would come in right at 30 mbps.
