Indeed; you can't build a quantum CPU with D-Wave's system.
It's conceptually more similar to a GPU which can solve a specific subset of (non-embarrassingly-parallel) problems in polynomial rather than exponential time, with the published number of qubits essentially being the amount of working memory available.
In practice these machines would probably be found optimizing certain steps in machine learning algorithms.
