One of the problems (QUBO) used maps directly to quantum annealing, meaning that the calculation can be performed on D-Wave's custom chip. In that case, the hardware dominates, coming in about 3,600 times faster than the closest software competitor. Using the newer chip and a 503-bit problem, D-Wave's advantage went up to 10,000 times faster.
Up to 10k times faster if the problem paremeters suit D-Wave's hardware. I'm impressed.
Q.comps and graphene will rock our world. Probably.
