Yeah, but they only looked at neurons. Compute ability comes three things: switching speed, memory and communication speed. You need all three. If you restrict one there comes a time where you can't speed up no matter how much you increase the other two. I'm not sure what correspondence neuron count has to those, but two other things looks like they would have at least the impact of neuron count, and there are synapse and axon performance and arrangement. Synapses I guess correspond roughly to memory, and axon's are the wires. To give a feel for the importance of these, the final maturation of the human brain that happens at age 20..25, turns a teenage brain into a adult brain, is apparently re-wiring those axon's and synapses. They don't measure either, probably because no one knows how. But that means their comparison is pretty limited.
