The problem is that intelligence isn’t a quantitative measure. I can’t measure “smarter”.
If I just want to know about the number of computations, then we can estimate that the human brain performs 10^14 operations/second then a machine operating at the Landauer limit would require about 0.3 microwatts to perform the same number of operations at room temperature.
The human brain uses something like 20 watts of energy (0.2*2000 calories/24 hours).
If that energy were used to perform computations at the Landaur limit then computational performance would increase by a factor of 6.5*10^7, to approximately 10^21 computations. But this only provides information about compute power. It doesn’t tell us anything about intelligence.
Intelligence can be defined as the ability to use knowledge and experience together to create new solutions for problems and situations. Intelligence is about using resources regardless of computational power. Intelligence is as simple as my browser remember a password (which I don’t let it do). It is able to recognize a website and pull the applicable data to auto fill and login. That is a kind of primitive intelligence.
