There are cloudy differences mentioned here, but I feel there are more differences.

What are the differences between High Volume Customer Portal license and Authenticated Website license? I am aware that these licenses are very similar and have very few differences between them.
Is there any table explaining the differences between these two licenses?
Edit: Please note that High Volume Customer Portal license is different from Customer Portal Manager license, hence my question is not a duplicate of this question: Customer Portal Manager vs Authenticated Website.
