Models of Computation by John E. Savage
This book, written for graduates, covers general subjects on computational models, logic circuits, and memory machines, with advanced subjects being parallel computation, circuit complexity, and space-time trade-offs; therefore, it's a very thorough course on computational models and their complexities.
