Intel 7 is our latest HVM node, while TSMC is entering HVM on 2nm.
Intel Fabs are at least 1.5 generations behind.
Imagine if a customer comes to us and asks us to make a chip and we give a chip that is 3.5 times bigger in dimensions than what TSMC can make. Or > 12x larger in area.
Simply, Fabs aren't worth the real estate they are on.
