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 sufficient performance for daily use, it has reduced its size to 297.5mm×212mm, which is almost equivalent to the area of a piece of A4 paper. The thickness is only 12.99mm, and the weight is controlled at about 1.05kg.
In addition, the RedmiBook Air 13 also comes standard with a good screen, a 13.3-inch narrow-edge full screen, with a screen-to-body ratio of 89%, a color gamut of 100% sRGB, and a resolution of 2560×1600, ensuring daily life Processing text, viewing web pages, watching videos, etc. can have the most delicate picture.
There are two versions of RedmiBook Air 13 this time, the main difference is the CPU model. This time, we received the i7-10510Y version with the highest configuration and the optional i5-10210Y. They are all part of the Ice Lake tenth generation core manufactured by the 10nm process. They are all 4 cores and 8 threads, and the thermal design power consumption is only A mere 7W, which is less than half of the traditional U-series low-voltage and light-weight processors. Next, let us pass a detailed evaluation to see what kind of experience RedmiBook Air 13 has.
RedmiBook Air 13 Design & Appearance
The A-side of RedmiBook Air 13 is still the familiar all-metal + simple LOGO style. The screen size of RedmiBook Air 13 is 13.3 inches, the resolution is 2560×1600, and it has a 100% sRGB color gamut. The design of the three-sided narrow frame, the screen ratio is 89%, and there is no front camera, the advantage is that the top frame is controlled more narrowly.
The screen-to-body ratio is as high as 89%, and the left and right borders are only 3.35mm. The power button is integrated with the keyboard keys and is placed in the upper right corner. The keys feel very crisp and the key travel is short. The microphone of the RedmiBook Air 13 is hidden and arranged at the bottom of the B side, next to the LOGO on the bottom border of the screen. The interface is mainly concentrated on the right side, with two full-function Type-C ports and one 3.5mm interface. There is only an air outlet on the left. The matching charging adapter has a maximum output power of 65W, compatible with multiple PD protocols, and can charge mobile phones.
There is a horizontal row of heat dissipation grilles on the D side. After all, the Y-series ultra-low-voltage processors do not generate much heat, and they do not require high air intake. Disassemble the bottom cover, you can see the internal structure of RedmiBook Air 13. The battery has a capacity of 41Wh, a single heat pipe and a single fan for heat dissipation, two air outlets, and the memory is welded and cannot be replaced.
The wireless network card is Intel AX200D2WL, supports Wi-Fi 6, 2T2R, supports 160MHz bandwidth, and has a maximum wireless rate of 2.4Gbps. The solid-state drive is Samsung PM881, M.2 interface plus SATA protocol, and the capacity is 512GB.
The machine tested in this review is the highest configuration among the three specifications of RedmiBook Air 13. It is equipped with an i7-10510Y processor, 4 cores and 8 threads, a base frequency of 1.2GHz, a maximum core frequency of 4.5GHz, a TDP of 7W, and a configurable maximum TDP of 9W, the nuclear display has not changed compared with the previous generation, it is UHD Graphics 617, the frequency is 300MHz-1050MHz.
RedmiBook Air 13 scored 473.8 in single thread and 1950 in multithread in CPU-Z.
Chess running points
RedmiBook Air 13 has a performance multiplier of 20.56 in the chess benchmark test, with a score of 9868 thousand moves.
In CineBench R15, the i7-10510Y of RedmiBook Air 13 scored 129cb in single thread and 517cb in multithread.
In CineBench R20, the i7-10510Y of RedmiBook Air 13 scored 310cb in single thread and 839cb in multithread.
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.
As an ultra-low-voltage CPU, the performance of the i7-10510Y’s core display is actually more suitable for daily use in video decoding and system graphics interface rendering. But if there is a real need, the game is not impossible.
For the online game “League of Legends” with lower configuration requirements, 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 more appropriate 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.

5. Temperature endurance test: the temperature is stable at 54℃, and the endurance can reach 7 and a half hours
An endurance test
Use PCMark 8 Work accelerated to test the battery life performance of RedmiBook Air 13. Under the premise of 50% battery power, Bluetooth, Wi-Fi turned off, and battery management biased toward battery life, the battery life is 7 hours and 39 minutes. The battery life test is smaller, so the battery life in daily use should be better.
Bake machine test
Although the TDP is limited to 7W, the i7-10510Y still has about 20 seconds of turbo frequency time. During this period, the CPU power is maintained at about 24W, the full core frequency is 2.99GHz, and the temperature will reach 76°C.
After 20 seconds, the CPU power will be reduced to about 14W, and gradually reduced to about 7W within 5 minutes. After baking for 30 minutes, RedmiBook Air 13 can maintain 7W power, the temperature is only 54°C, and the full core frequency is 1.3GHz.
RedmiBook Air 13 Verdict
