The Game Boy CPU is Sharp's 'LR35902', which has functions similar to those of the Intel 8080. The operating clock of the LR35902 is 4MHz, and it was 'technology 10 years ago' when the Game Boy appeared. Game Boy was designed with the idea of 'horizontal thinking of dead technology ', and by using a little old technology at that time, the price was kept down and the learning cost of the developer was also kept low.

The Tegra on the Nintendo Switch is a power-saving chip that runs at 10W, but it still needs a fan for cooling. In normal play, it is rare to be aware of the existence of fans, but if you check the CT scan image of Nintendo Switch, you can see that it is equipped with a heat pipe and a small fan to transfer heat to the fan.
