I did it a couple of weeks ago (AMS - BOS - RDU) and I'm in pretty good shape and walk really fast and it still took me about 10-15 minutes.
Try not to check any luggage, that will make this more difficult (though not impossible) and of course if you have GE that will expedite things.
Note: You don’t have to just walk. International is Terminal E, and DL is Terminal A. Many free bus shuttles circle all the terminals; you can ask a driver to confirm but most of the airport shuttle buses will get you without walking from E to A in the same time or less as walking.
