The question of how many hertz in the Xiaomi Mi 9T often arises among users who choose a smartphone for gaming or consumption of multimedia content.This device, released in 2019, has long been considered the benchmark of the mid-range, offering flagship specs at an affordable price.
Many people confuse the clock speed of the processor and the refresh rate of the screen, although these parameters dramatically affect different aspects of the device. In this article, we will discuss both indicators for the Xiaomi Mi 9T and Mi 9T Pro model, so that you understand the real performance of the gadget.
It’s worth noting that the standards of the mobile industry are changing rapidly, and what was the norm a few years ago can be considered a basic level today, and understanding these characteristics will help you make an informed decision about buying a used device or choosing accessories.
Display refresh rate: 60 Hz or more?
The main parameter most users are interested in is the refresh rate of the matrix. In the case of the Xiaomi Mi 9T and its Pro version, the manufacturer installed a classic panel at 60 Hz at the time. This means that the image on the screen is updated sixty times per second, which is the standard for most video and television broadcasts.
Despite the lack of High Refresh Rate (90Hz or 120Hz) technology, which has become popular in newer models, the picture on the Xiaomi Mi 9T remains juicy and sharp. It uses a high-quality AMOLED matrix from Samsung with a resolution of 2340×1080 pixels, providing deep black and high contrast.
⚠️ Note: Do not attempt to software unlock 90Hz on this device through an engineering menu or root right.The hardware of the display controller is physically limited to 60Hz, and such manipulations may result in unstable system operation or image artifacts.
For everyday tasks, watching YouTube and working with social networks, 60 hertz is more than enough. The human eye has difficulty noticing the difference between 60 and 90 Hz in static interfaces, although in dynamic scenes the smoothness is higher.
Processor performance: clock frequency of cores
If we talk about computing power, the situation is different. The basis of the smartphone is a chipset Qualcomm Snapdragon 730 in the normal version and Snapdragon 855 in the Pro version. The clock frequency of the cores is the number of operations that the processor can perform in one second, and it is measured in gigahertz (GHz).
The standard Xiaomi Mi 9T uses an 8-core configuration. Two powerful Kryo 470 Gold cores operate at frequencies up to 2.2 GHz, and six energy-efficient Kryo 470 Silver cores operate at 1.8 GHz. This big.LITTLE architecture allows you to balance between performance and autonomy.
The Mi 9T Pro version has a more powerful Snapdragon 855 processor. Its main Kryo 485 Gold core is overclocked to 2.84 GHz, three production cores run at 2.42 GHz, and five economical ones run at 1.8 GHz. This provides a significant increase in speed in heavy tasks.
How to find out the exact frequency of the processor?
It's worth remembering that the maximum frequency is achieved only under load. In downtime, the system automatically reduces the hertz to save battery power, which is normal for MIUI energy saving algorithms.
Mi 9T and Mi 9T Pro: What’s the Difference?
Often users can’t decide between the two modifications of the device, believing that the difference is only in the name, but the internal components are significantly different, which directly affects the performance and gaming capabilities.
The main difference is the graphics accelerator, which features the Adreno 640, which is significantly more powerful than the Adreno 618 in the conventional model, which is critical for today's games that require high frame rates.
Below is a table comparing the key technical characteristics of both models:
| Characteristics | Xiaomi Mi 9T | Xiaomi Mi 9T Pro |
|---|---|---|
| Processor | Snapdragon 730 | Snapdragon 855 |
| CPU frequency (max) | 2.2 GHz | 2.84 GHz |
| Graphics | Adreno 618 | Adreno 640 |
| Memory (RAM) | 6GB | 6/8 GB |
If you want to choose between these models, you need to be more specific to your needs, if you want a smartphone for messengers and navigation, the regular version will be enough, and if you want to play games, you should consider a Pro modification.
☑️ How to check the originality of the processor
The influence of frequency on gameplay
Gamers are often concerned about how many FPS (frames per second) will be able to give Xiaomi Mi 9T. The screen with a frequency of 60 Hz is physically not able to display more than 60 frames per second, so there is no point in chasing high values in the settings of games.
The Snapdragon 730 processor confidently pulls popular games like PUBG Mobile and Call of Duty on medium and high graphics settings, providing a stable 40-50 FPS. In the Pro version, the performance margin allows you to play with maximum settings.
However, you should consider heat generation. With prolonged load, the system can reduce the clock speed of the processor (trottling) to avoid overheating, which leads to a temporary drop in the number of frames per second.
⚠️ Note: Using external coolers or removing the case during long gaming sessions will help to maintain a high CPU frequency and avoid lags due to overheating.
For competitive games where reaction is important, 60Hz is an acceptable minimum, but not an ideal, and yet the developers have done very well to optimize games for this platform.
💡
The 60Hz screen limits the maximum number of visible frames per second, but the Snapdragon 855 processor in the Pro version is able to keep this figure stable in heavy games.
Display settings and calibration
In the MIUI shell installed on the Xiaomi Mi 9T, there are no native settings to change the refresh rate, since the screen is hardware fixed at 60 Hz. However, the user can adjust the color gamut and resolution.
To access the advanced screen settings, go to Settings → Screen → Color and saturation. Here you can choose from the preset profiles or manually adjust the colors for more accurate color reproduction.
Some enthusiasts try to change the pixel density (DPI) through a developer menu, and this is done by typing a command into ADB or through special applications, but it requires caution.
adb shell wm density 400Changing the DPI doesn't affect the hertz, but it does scale the interface, making elements larger or smaller. The standard value for this device is usually around 411 or 420 dpi.
