I don't know how much more the larger packages cost, but it was enough that Intel really really didn't want to move off 16-pin packages, which caused problems for the 4004 and 8008 processors. In addition, the larger packages took up more space on the circuit board which was a serious disadvantage, especially when you had a board full of memory chips.
