Uh, there is a mistake. The fourth generation i5 5200U and the sixth generation i5 6200U are dual core and four thread processors. They are real dual cores, but can be simulated as four cores for use.
The production process of the sixth generation i5 6200U has been upgraded to 14nm, which is more power saving. Its main frequency is slightly higher than that of the fourth generation i5 5200U, and its architecture is more advanced.The overall performance is certainly improved compared with the fourth generation i5 5200U, but the performance is still not as good as the fourth generation standard pressure version i5 4210M/i5 4210H. The last two standard pressure versions i5 still suppress the low-voltage version i5 i7
In terms of performance, the i5-4210m is slightly better, which is suitable for playing games; The i5-6200u is a six generation low-voltage processor. While taking into account the performance, it also pays attention to reducing power consumption. The notebook will have a stronger endurance;So depending on your usage scenario, if there is no need to go out for use, you can choose the former. If there is a scenario of going out to work, and if you buy a laptop not only for games, but for office work, the latter will be more suitable;
