Core m3 and i5 are different models of Intel processors.In terms of performance, i5 is usually more powerful than m3.
First, i5 processors have higher clock speeds and more cores.This makes it perform better in multitasking and high load applications.In contrast, m3 processor is suitable for general daily use, such as browsing web pages, light office work, etc.
Secondly, in terms of graphics performance, i5 processors are usually equipped with independent graphics cards or integrated powerful graphics cards.This makes it have better performance in games, video editing and image processing.However, m3 processors only have integrated graphics cards and may be limited in these applications.
Finally, in terms of power consumption, m3 series usually has lower power consumption and cooling requirements.This means that they can provide a long battery life and are better than the i5 series in terms of heat dissipation.
If you plan to purchase the Xiaomi Air laptop and mainly use it for general daily use (such as Internet, office, entertainment, etc.), then the Core m3 processor may be enough to meet your needs.However, if you need to deal with more multitasking, graphics requirements or some professional applications, then the i5 processor version may be more appropriate.In the end, you can decide which model is the best choice according to your own use needs.
The i5 should be better, because the Core m series focuses on the endurance function, that is, the power consumption is slightly smaller, which should be similar to the i3, but there is still a gap with the i5, Passimark processor performance score: m-5y70：3080 m-5y10：2840 i3 4000m：3240 i5 4200m：4070
13 and 12 inches are all about personal needs. If you are playing at home or at school, and there is not much portability requirement, 13 inches is better. It is more comfortable to watch movies, otherwise it is 12 inches.In fact, the performance of M3 and I5 on this kind of office slim notebook can't be used very well, so I personally say that the difference is only one-fifth to one-quarter at most.I can't feel it in use.
