The question of the real performance of a smartphone is often decisive when buying, especially when it comes to time-tested models like the Xiaomi Redmi Note 9T. This device, which came to market as an affordable entry into the world of 5G, still arouses keen interest among users looking for a balance between price and functionality. Many potential owners wonder how many points the Redmi Note 9T scores in the popular benchmark Antutu, and whether this indicator meets modern requirements?
The answer to this question is not as clear as it may seem at first glance, since the final figure depends on many factors: the version of the operating system, the number of background processes and even the ambient temperature. On average, the device demonstrates results typical of the middle segment, but the range of values can be significant. Understanding these nuances will allow you to objectively assess the capabilities of the gadget before buying or diagnosing.
In this article, we will look at which metrics are normal and which are indicative of problems in the system, and we will analyze the impact of the MediaTek Dimensity 800U processor on overall speed and find out why the numbers in different tests may differ.
Performance architecture: processor and memory
At the heart of the smartphone is the MediaTek Dimensity 800U chipset, which is made using a 7nm process technology. This platform includes eight cores: two powerful Cortex-A76 cores with a frequency of up to 2.4 GHz and six energy-efficient Cortex-A55. This configuration determines how many points in Antutu can squeeze the Redmi Note 9T in various load scenarios. Mali-G57 MC3 graphics accelerator takes over the processing of graphics, which is critical for game tests inside the benchmark.
The second most important component that directly affects the final score is the type and speed of RAM. Depending on the region and modification, the device could be equipped with 4 or 6 GB of RAM standard LPDDR4X. The difference in memory bandwidth can give a noticeable increase in synthetic tests, especially in the subsection of CPU and UX (User Experience).
Technical details of the chipset
Also worth noting is the role of built-in storage: Using UFS 2.2 memory instead of the older UFS 2.1 standard provides faster write and read speeds for large files, which directly affects the performance in the UX section of the benchmark, making the interface more responsive.
Real Antutu metrics: versions and comparisons
When testing, it is important to consider the version of the benchmark itself, as the evaluation algorithms are constantly changing. For Xiaomi Redmi Note 9T, the data obtained in the Antutu V8 and V9 versions, which are most often found in open databases, are relevant. In newer versions (V10), the results may be higher due to changes in the weightings of the tests.
The typical score for a standard configuration (4/64GB or 4/128GB) ranges from 330,000 to 360,000 in the Antututu V9. This is a fair figure for the middle class, allowing you to comfortably work with social networks, navigation and light games. However, owners of versions with 6GB of RAM sometimes record higher values, reaching 370,000 to 380,000 points.
The variation in results is often due not only to hardware, but also to software environments. MIUI global firmware may behave differently than the Chinese versions of HyperOS or CN MIUI, due to differences in pre-installed software and background services. So, when comparing your numbers with other users' results, always check the version of the software.
Factors Affecting the Test Results
Why is your smartphone going to be lower than expected? There are a number of variables that can significantly understate the final figure in the benchmark. The first and most obvious factor is the temperature of the case and the processor. If the device is heated before the test is run, the trottling system will force the core frequencies to avoid overheating, which will lead to a drop in performance.
The second important aspect is the background activity of applications. Even if you close all windows, some processes may continue to consume CPU and RAM resources. Before starting Antutu, it is recommended to clear the memory and close all unnecessary applications through Task Manager.
💡
To get the most accurate result, turn on the Do Not Disturb mode and turn off the automatic brightness of the screen before starting the test.
Many Xiaomi smartphones automatically limit performance if the charge drops below 20-30% to extend battery life. For honest testing, charge the device to at least 50-60%.
⚠️ Warning: Don't run performance tests immediately after you upgrade or install heavy apps. Give your smartphone time (30-60 minutes) to optimize files and background processes, otherwise the result will be artificially underestimated.
Comparison with competitors and predecessors
To understand the Redmi Note 9T’s place in the performance hierarchy, it’s useful to compare it to direct competitors of the same period and predecessors: The main rival was the Samsung Galaxy A52 4G based on the Snapdragon 720G, which in the Antutu V9 scored approximately 280,000 – 300,000 points. Thus, the MediaTek Dimensity 800U demonstrates a noticeable advantage in clean computing power.
If we compare with its predecessor in the face of the Redmi Note 8 Pro (Helio G90T), the results are comparable, although the architecture of the cores. Note 9T benefits from a more modern process technology and energy efficiency, which allows you to keep a high pace of work longer without overheating.
Below is a table with comparative performance data in Antutu (V9 averages):
| Smartphone model | Processor | Average score (Antutu V9) | Performance class |
|---|---|---|---|
| Redmi Note 9T | MediaTek Dimensity 800U | ~350 000 | Mid-range (Mid-range) |
| Redmi Note 8 Pro | MediaTek Helio G90T | ~290 000 | Mid-range (Mid-range) |
| Samsung Galaxy A52 4G | Snapdragon 720G | ~285 000 | Mid-range (Mid-range) |
| Poco X3 NFC | Snapdragon 732G | ~340 000 | Mid-range (Mid-range) |
💡
The Redmi Note 9T is ahead of many of its competitors in the same price segment thanks to 5G support and the more powerful Dimensity 800U chipset.
Optimizing the system for maximum scores
If you want to get the most out of your Redmi Note 9T, you can use a number of software tweaks. First of all, make sure you have the latest available version of MIUI. Engineers are constantly releasing patches that improve memory and processor performance.
There is also a hidden developer mode that allows you to disable animations and limit background processes. To access it, you need to click on the build number several times in the About Phone section. Once you activate the developer menu, you can find the "Limit of background processes" item and set the value "No more than 2 processes".
☑️ Checklist before test
Another effective method is to clean the storage: if the free space on the internal drive is less than 10-15%, the write speed may fall, which will negatively affect the UX partition in the benchmark, delete unnecessary files or transfer the photo to the cloud server.
The effect of temperature and trottling
The long-term load that Antutu creates is a stress test for the cooling system. Redmi Note 9T is equipped with a passive cooling system, and during prolonged operation at maximum frequencies, heating is inevitable. Once the processor temperature reaches a critical point (usually about 45-50 degrees on the SoC sensor), the trottling mechanism is activated.
Trottling is the process of forcefully reducing the CPU clock speed to reduce heat output. In short tests, this may not be noticeable, but in long Antutu sessions, you can see FPS drop in graphic scenes. This is normal behavior to protect the device from damage.
⚠️ Warning: Do not attempt to artificially cool your smartphone by putting it in the refrigerator or under a stream of cold water during the test. A sharp temperature drop can cause condensation inside the case and the electronics to fail.
For stable results, it is better to conduct tests in a room temperature, away from direct sunlight and heating devices, and removing the protective cover during the test will also help improve heat sink.
