It's bound by the slowest shared resource in the system (Amdahl's law). That could be disk I/O, memory bandwidth, or power budget.

That isn't what Amdahl's law says. Amdahl's law is an equation describing the theoretical paralellizability of a given task. It doesn't have anything to do with systems bottlenecking on one resource vs another.
