If you often look at Xiaomi mall, you will find that there are currently three generations of Redmi Note series products on sale at the same time, namely Redmi Note 9 series, Note 10 series and Note 11 series. Among them, the Note 9 series is a product released in 2020. It has been almost two years so far. Many people can’t understand why it is still on sale. They think that buying the Redmi Note 9 series in 2022 is an IQ tax. In fact, the Redmi Note 9 5G is more cost-effective than Redmi Note 11 5G. Let’s take a look.
First of all, in terms of processor, Redmi Note 9 5G is equipped with MediaTek Dimensity 800U processor, and Redmi Note 11 5G is equipped with MediaTek Dimensity 810 processor. From a numerical point of view, 810 is greater than 800. Is that really the case?
The CPU of MediaTek Dimensity 800U uses 2*A76 architecture + 6*A55 architecture. The main frequencies are 2.4GHz + 2.0GHz respectively. The GPU is Mail-G57MC3. The CPU of MediaTek Dimensity 810 also uses 2*A76 architecture + 6*. A55 architecture, main frequencies are 2.4GHz+2.0GHz respectively, but the GPU is Mail-G57MC2.
That is to say, the CPU performance of MediaTek Dimensity 800U and MediaTek Dimensity 810 is the same, but the GPU performance of MediaTek Dimensity 800U is better. This means that compared to Redmi Note 9 5G, Redmi Note 11 5G has gone backwards in terms of performance.
Secondly, in terms of imaging, Redmi Note 9 5G uses a 48MP main camera with a sensor size of 1/2 inch, a single pixel of 0.8um, and a four-in-one pixel of 1.6um. Redmi Note 11 5G uses a 50MP main camera, the sensor size is only 1/2.76 inches, the single pixel size is 0.64um, and the four-in-one is 1.28um. For the secondary camera, both are 8MP ultra-wide-angle, and the Redmi Note 9 5G also has an additional 2MP macro, so the Redmi Note 11 5G has also gone backwards in terms of imaging.
The third is the price. The 8+128GB version of Redmi Note 9 5G only costs 1,299 yuan, while the price of Redmi Note 11 5G is 1,399 yuan. This is not the point. Redmi Note 9 5G thoughtfully uses a three-card slot design, which can use dual SIM cards and SD cards at the same time. Redmi Note 11 5G can only use dual SIM cards or one SIM card and one SD card. From this point of view, Redmi Note 9 5G will be very practical for users who require large-capacity storage. After all, the price difference if you buy the 256GB version directly is more than 100 yuan.
The only advantage of Redmi Note 11 5G is that the screen supports 90Hz refresh rate and has faster 33W charging. But for thousand-yuan phones, the improvement in high refresh experience is not big. After all, the processor is the bottleneck that limits performance. At the same time, with the blessing of a 5000 mAh battery, basically one charge a day is enough, and the perception of fast charging is not strong. On the contrary, Redmi Note 9 5G has a stronger processor and a more favorable price, which is the biggest selling point. In this way, do you still think Redmi Note 9 5G is an IQ tax?
