The Redmi Redmi K50 series has been officially released, and it is said that there are many rice noodles that intend to start these two new machines. However, at the K50 conference, Xiaomi also brought another upgrade of the Redmi K40, that is, the Redmi K40S, which is much cheaper than the Redmi K50, and is equipped with the Qualcomm Snapdragon 870 processor, which was popular last year. Therefore, many netizens have asked: What upgrades are there compared with the previous generation of K40, and which one is more worth buying than the K50?
As an upgraded version of Redmi K40, the improvement of K40S is still relatively obvious, its heat dissipation system has been upgraded from the previous copper tube to VC liquid cooling heat dissipation, the total heat dissipation area has also increased by 400%, and the VC area has reached 3112mm. It also adds a 120-frame mode for Honor of Kings, and can run at full frame rate. Of course, Qualcomm Snapdragon 870 is also no problem to play large-scale 3D mobile games such as "Original God".
The redmi K40S's battery capacity remains inconvenient at 4500mA, but the charging power is upgraded from 33W to 67W, charging faster, and it can be fully charged in 38 minutes. This feature is still useful for players who play games regularly.
In addition, the main camera of the Redmi K40S still maintains the 48-megapixel IMX 582, but with the addition of OIS optical image stabilization, photos and videos are more stable, and the night scene ability has also been greatly enhanced. This camera can still meet most needs in daily use.
In addition, the Redmi K40S still retains the functions and designs that were well received by the previous generation, such as the Samsung E4 AMOLED screen, the X-axis linear motor, the Dolby stereo dual speaker, the multi-function NFC, the infrared remote control and other functions are readily available.
In addition, the appearance of Redmi K40S has also changed greatly compared with the previous generation, its rear camera module is more similar to the K50, and the three cameras are arranged in an equilateral triangle. However, the middle frame of the K40S adopts a straight-edged appearance, and the middle frame of the K50 is still relatively rounded.
Compared with the Redmi K50 and K40S released at the same time, the main difference is that its screen is a 2K resolution Samsung flexible straight screen, which supports a refresh rate of 120Hz, and full DC dimming. Although the K50 has a higher pixel density on the screen, the display effect will certainly be better than that of the K40S.
In addition, the Redmi K50 is equipped with media fakage 8100 processor, which adopts TSMC's 5nm process and has four 2.85GHz A78 cores + four 2.0GHz A55 cores. The Qualcomm Snapdragon 870 is a 7nm process, although the main frequency of 1 super core reaches 3.19GHz, but the main frequency of the three large cores is only 2.42GHz, and the main frequency of the three A55 cores is 1.8GHz. So from the perspective of performance and power consumption, Tianji 8100 is definitely better than Qualcomm Snapdragon 870.
And Redmi K50 also has a built-in 5500mAh large battery, also supports 67W wired fast charging, and the endurance is much stronger than the Redmi K40S.
So in comparison, although the Redmi K50 is 600 yuan more expensive than the K40S, it has obvious advantages in the three aspects of screen, processor performance, and battery capacity. So if you are a user with higher requirements for the performance and battery life of the mobile phone, it is better to choose the Redmi K50. Of course, the overall configuration of the Redmi K40S can also meet most of the daily use and game needs, so if the budget is not high, the K40S is also quite good.
