At the energy dissipation rate of 10^-27 joules per logic operation, times 10^27 operations per second, gets you a total power consumption of 1 joule-per-second, or 1 watt. 1 watt! That's 1/20th of what our meat brains run on to achieve a paltry 10^18 operations per second.
10^27 divided by 10^18=1,000,000,000. So a cubic centimeter of helical logic-based computronium is 1 x 10^9 times faster, while simultaneously being 20 times more energy efficient, than an average human brain, which has a volume of 1000+ cm^3.
That's not counting the refrigeration requirement, of course, but with vacuum flask insulation and futuristic refrigeration technology, I'd conservatively guess a few tens of watts could take care of that in baseline-shirtsleeve-environments. Of course in deep space at 30 Kelvin, or so, little more than passive radiator panels would be required.
