Prime rib is just a saying. Rib eye and prime rib are the same thing. A Ribeye is when you cut it into steaks before cooking and prime rib is a ribeye that is sliced after cooking.
Go and age that thing! Will taste delicious after 4 weeks :becky:
A prime rib is a prime grade rib roast. If it's not prime grade, it's a rib roast. If cut into steaks they're rib eyes (grade not being a factor then).
