They're measuring asymptotic performance (scale), not wall clock time, and testing quantum algorithms with known better asymptotic performance than the equivalent classical ones. They could run the classical algorithms a factor of 1,000,000× slower and reach the same conclusion, that the D-Wave's quantum annealing process is asymptotically equivalent (scales equivalently) to classical algorithms.
