Two interesting XOR circuits inside the Intel 386 processor

I've looked at a few higher-power chips, such as the venerable 7805 voltage regulator, but I don't know if that's high-power enough for you :-) There's no high-power secret inside that chip except it uses large transistors.

Parent might be thinking of those Gallium-Nitride FETs that enable manufacturers to build suspiciously small power bricks.

I thought that was due to the higher switching frequency of the power transistors, perhaps unrelated to higher current draw in the transistor?
