I think that comparison is just to illustrate the computational improvements. In other words, the new system is 10x faster. As Elon said on the call, that means they can now process all the cameras at full resolution and full framerate, which can improve accuracy and therefore ability and safety... which sounds like the real world benefits you're looking for.
