On February 9, it was reported that Lu Weibing, vice president of Xiaomi Group and general manager of Redmi, officially announced that the Redmi K40 would be released on February 25. In the afternoon, Xiaomi Notebook also announced that RedmiBook Pro would be released on February 25.

February 25 is the 14th day of the first month, and the release time of Redmi K40 is the same as the previous "wrong hand disclosure" of JD and Zhihu. As early as February 4, the new Xiaomi 10 mobile phones suspected of being Redmi K40, Redmi K40 Pro and Snapdragon 870 have passed 3C certification. The models of the three mobile phones are M2012K11AC, M2012K11C and M2102J2SC. The "old friend" 33W fast charge is used. The charging head model is MDY-11-EX, and the maximum output is 11V 3A, 33W.

Redmi officially announced some core configurations on January 11. The Redmi K40 will be a Samsung E4 straight screen from 888+2999 yuan for Snapdragon. The latter is "probably the most expensive straight screen", and there will be more than 4000mAh batteries, and the appearance pictures leaked before are false.

In addition, up to now, there are still computer users who dream that the K40 will have a 2K resolution central perforated straight screen, but it is almost certain that the K40 will be a 1080P+resolution straight screen. The 2999 yuan Snapdragon 888+E4 material screen also wants 2K resolution, which is too high for bicycles. K40 Pro or K40 Pro+has the opportunity to carry 2K screen, but it will not be K40 for 2999 yuan.

On the side of RedmiBook Pro, the official declaration is "redefinition", which will officially retire the ancestral mold, and add a front camera and a full-size keyboard with backlight.

As early as December, Xiaomi notebooks equipped with Intel's 11th generation Core TigerLake-H35 series processors have appeared on GeekBench. They are respectively equipped with i7-11370H and i5-11300H, both 4-core 8-thread, 35W TDP. I5-11300H is a three-level cache with a default frequency of 3.1GHz, a Remax of 4.4GHz and 8MB. The i7-11370H is a 3.3GHz, 4.8GHz, 12MB three-level cache.

In terms of the performance of the two CPUs, the difference between single core and multi-core is about 130 points and 100-200 points higher. I5-11300H single core 1430, multi core 4800 or so; I7-11370H single core 1570, multi core 5060 or so.
