There are also process generations within the same process "size". Intel has 14mm, 14nm+, 14nm++, and now 10nm (the limited # of 10nm skus released so far is because of all the 10nm problems) and 10nm+. I thought I read somewhere that while 10nm+ was originally intended for Ice Lake and beyond, they're considering moving some 10nm products to 10nm+ early because the original 10nm process yields are so awful.
