Cream cheese is cheese. It's a fresh cheese (not aged) similar to the French Neufchatel. In fact, it was "invented" in the USA by someone trying to create French Neufchatel.
Cream cheese has a higher fat content than Neufchatel. If you check out a package of Philadelphia brand 1/3 less fat cream cheese, you'll see that it's labeled as Neufchatel.
