tsmc n2 i think (2nm)
They skipped 5nm and 3nm, and that is indeed an accomplishment.
I hope the yeilds are high.
They have Intel 7, Intel 4, Intel 3 nodes. Anyways, Intel's names do not equal to the same number on TSMC. They're usually 1 or 1.5 generation behind with the same name.
So Intel 3 would be something like TSMC N6.
