The "nm" hasn't meant anything physical for a long while. However, Intel's 14nm was generally comparable not to TSMC's 14nm but TSMC's 10nm, and Intel's 10nm to TSMC's 7nm. When Intel was running two nodes ahead, this naming disparity wasn't a marketing issue, because Intel 14nm (=TSMC 10nm) was still competing with TSMC 22nm. After Intel face-planted, it became a liability, so the nodes were renamed to match industry expectations. So Intel 4 is broadly comparable to TSMC N4.
