Brains use chemical interactions within a scaffold built biologicaly with
cells.
Transistors, as used today, are built differently. If 7 transistors were
used
to store each bit, and the routing required nn-transistors, and each
transistor
consumed xx pico Watt then you could compute the power consumption
at a clock rate of 1GHz. (for a given size of die). Think of a brain
operating
at a frequency 100 million times faster and with as many interconnections
as you wished to build.
