RedmiBook Air 13 Review: Ideal For Light Work

RedmiBook Air 13

With the upgrading of manufacturing process and technology, low-voltage CPUs for ultrabooks can finally achieve high performance. Now, they can maintain a portable body shape and run some heavy applications. Performance improvement is naturally a good thing, and more usage scenarios are also the result that everyone is happy to see. But the positioning of the final product still has to be determined according to the needs of users.

For people who often run around and use computers only for office, Internet and other light application scenarios, the size, weight, and battery life of the notebook are more important than performance. The recently released RedmiBook Air 13 is a thin and light notebook that focuses on the pain point of compactness and portability. On the basis of ensuring that the performance is sufficient for daily use, it has reduced its size to 297.5mm×212mm. This is almost equivalent to the area of ​​an A4 paper. The thickness of only 12.99mm and the weight are controlled at about 1.05kg.

In addition, the RedmiBook Air 13 comes standard with a good screen. A 13.3-inch narrow-edge full screen has a screen-to-body ratio of 89%, a color gamut of 100% sRGB, and a resolution of 2560×1600.

There are two versions of the RedmiBook Air 13. The main difference is the CPU model. This time, we received the i7-10510Y version with the highest configuration. But there is also an i5-10210Y variant. They are all part of the Ice Lake tenth generation Core manufactured by the 10nm process. They all have 4 cores and 8 threads, and the thermal design power consumption is only 7W, which is less than half of the traditional U-series low-voltage processor.

The front side of the RedmiBook Air 13 still uses the familiar all-metal + simple logo style.

There is only an air outlet on the left.

The charging adapter has a maximum output power of 65W, compatible with multiple PD protocols, and can charge smartphones.

There is a horizontal row of heat dissipation grilles on the back. After all, the Y-series ultra-low-voltage processors do not generate much heat. So they do not require high air intake.

It took 489.822 seconds for the i7-10510Y to run wPrime v2.1 1024M with multiple threads, while it took 36.761 seconds to run 32M with a single thread.

Overall, compared to the previous generation i7-8500Y, the i7-10510Y mainly lies in its multi-core performance. Thanks to the improvement of 4 cores and 8 threads, the multi-core performance has been significantly enhanced, while the single core has almost nothing compared to the previous generation. Variety.

Gaming

As an ultra-low voltage CPU, the performance of this core display of the i7-10510Y is actually more suitable for daily use in video decoding and system graphics interface rendering. But if you want to play heavy games, it is just impossible.

For the online game ‘League of Legends’ with lower configuration requirements, the RedmiBook Air 13 can run smoothly. However, due to the high native resolution of the screen, in order to increase the frame rate and adapt to the best display size of the 13-inch screen, it is better to choose a resolution of 1280×720 for the game. If you want to further increase the resolution, you can choose to reduce some of the image quality settings to achieve a smoother experience.
