A lot.

They are really two different suttas.

One is a collection of disconnected practises.

The other describes unfolding of experience when the mind is established in right mindfulness, one after eachother, in sequence, the flow of the stream.

Try to compare, for example, how the factors of enlightenment are described in each sutta.

In one sutta they are merely listed and in the other sutta they flow into each other, one being the foundation for the next.
