I saw an interesting calculation, Google said that AlphaGo (configured with 1200 CPUs and 170 GPUs) consumes $3,000 per game of chess, and 10 cents per kWh is the energy consumption of 30,000 kWh per game of chess .
According to 4 hours per game of chess, the average human consumes 2,000 calories per day, and the human brain accounts for 20% of it, that is, 1.67 million joules of heat, 86,400 seconds a day, and the power consumption of the human brain is calculated to be 19 watts (brain per hour The average power consumption is very small regardless of sleep and wakefulness).
Computationally available, the power consumption of top AI is 370,000 times that of the human brain. And a typical 15-watt eight-core, 16-thread CPU can handle 99% of humans in any chess game.
The top artificial intelligence needs to use 370,000 times the energy consumption to get the human elite, while the ordinary people can be defeated by an ordinary CPU.
It can be seen that the efficiency of human utilization of energy is really remarkable. And how ingenious the machines that human beings have invented use energy too crudely.
Second, the huge gap in professional ability between human elites and ordinary people is terrifyingly scary.
