Yeah but AMD is not following after 2021. They will be following after 2020.Booking means to place orders. Fully booked implies all wafers are booked. I've used fully booked when phrasing Apple until today when that Digitimes article came out. Digitimes previously reported Apple would be using 3nm (or 2nm) in late '22 or mid '23, and I suspect for something due for a refresh then.
