A computer is a pretty bad analogy for a brain. But even so, 1 synapse is much much greater in complexity than 10 or 100 transistors. Each synapse is a complex system unto itself, which interacts with all kinds of cellular mechanisms which make up the highly dynamical system which dictates information processing within the neuron. So if we wanted to make a simulation with reasonable fidelity to the mechanisms of cellular information processing we know about, I would wager to guess it's more on the order of 1GPU == 1Synapse at a minimum. That's not to say that all of this complexity is required to reproduce consciousness in a meaningful way, but actual information processing in the brain is gob-smackingly complex.
