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.
Wow, I didn't realize Intel was slacking on top of their node rename. Sure their "10nm" was ahead at the time, but if they'd left the numbers alone they'd be a much closer match to everyone else today instead of even further off.
