They're both process nodes, with certain minor-ish differences here and there. TSMC calls theirs 7 nm, Intel calls theirs 10 nm.
Their performance characteristics might be around the same. In practice... who knows. We do know that Intel's current 10 nm CPUs are pretty much broken ~ best they could currently do was useless laptop-grade 2.5 GHz dual-core with no functional iGPU. Not sure about the HT, though.
