You might be right about brains being better at certain kinds of tasks, but I don't think it's right to think of them as having only one processing mode.
Someone else mentioned "Thinking, Fast and Slow", and I find it fascinating how closely the two thinking modes in that book seem to map to CPU (mostly serial) and GPU (parallel) processing. It also claims that people have natural preferences for each mode of thinking, which is super interesting as it suggests that the tasks that brains are best at performing will vary from person to person (I guess this is obvious, but perhaps gets lost when we start comparing to computers).
I'd bet on brains getting a lot of their efficiency from tight integration of CPU-like, GPU-like, and ASIC-like, and full on analog components. We'd probably have to apply deep-learning like approaches to the hardware design itself to get close.
