Comment Less power?? (Score 1) 96
Power is governed by change of states per second. It varies by the voltage, but by the square of the current. There's only so much saving from reducing voltage, too, as you run into thermal issues and electron tunnelling errors.
You are much, much better off by saying "bugger that for a lark", exploiting tunnelling to the limit, switching to a lower resistance interconnect, cooling the silicon below 0'C and ramping up clock speeds. And switching to 128-bit logic and implementing BLAS and FFT in silicon.
True, your tablet will now look like a cross between Chernobyl, a fridge-freezer, and the entire of engineering on the NCC-1701D Enterprise, but it will now actually have the power to play those 4K movies without lag, freeze or loss of resolution.
