Well, not necessarily. The key factors are heterogeneity and complexity rather than size. E.g., the difference between a stick of RAM (relatively homogeneous and simple) vs a CPU (highly diverse). In fact, when it comes to brains, larger cetaceans seem to have simpler structures when compared to human brains, even though they're larger in absolute terms.
