Apple M2 chip is an ARM-based chip with the second generation of 5 nm technology. CPU speed increased by 18%, graphics processor performance increased by 35%, and neural network engine speed increased by as much as 40%. The power consumption ratio of Mac computers using M2 chip is further broken, and the energy efficiency is higher than that of the previous generation M 1 chip. In addition, the memory bandwidth of M2 chip is 50% higher than that of M 1, and it is equipped with fast unified memory up to 24 GB.

However, compared with other chips, the system power consumption of M2 chip is less than half of 6800U, and the gap with Core i7- 1260P is even greater. The clock frequency of Arm chip is only as high as 3.5 GHz, while the clock frequency of AMD and Intel chip is 4.7 GHz, which has a great impact on efficiency, because most process nodes are optimized for the frequency of 3 GHz instead of 4.5 GHz.
