Basically its the difference between calculating a full volume and just the surface of that volume. The old chunks had to store points or cached bitmaps (depending on if it was the isometric method or the perspective method). The new method stores nothing, and generates the scene instantly based on the camera's viewing volume. As mentioned above, its really simple stuff (at least, as simple as this stuff gets!), not new - it is based on distance field marching and grid marching.
