We quantify the robustness of logical qubits preserved by the honeycomb code using a correlated minimum-weight perfect-matching decoder. We find a threshold of 0.2%-0.3% for the honeycomb code versus 0.5%-0.7% for the surface code in a CNOT circuit model; with native two-body measurements the honeycomb threshold is 1.5%-2.0%, and at 10^-3 error rates the teraquop regime is reachable with ~600 qubits.
