Why the number of cores is important for the Xiaomi Mi 9C
Choosing a smartphone is a matter of attention to detail, and the processor is key. The Xiaomi Mi 9C, launched in 2020, is still a budget choice for those who value price-performance balance. But how do you know how powerful a chipset is? The first question users ask is: how many cores are in the Xiaomi Mi 9C and how do they affect the device?
In this article, we will not only answer the main question, but also analyze the unique architecture of the Snapdragon 720G processor, which is the basis of the model. You will learn how the number of cores correlates with multitasking, playing PUBG Mobile or Genshin Impact, and compare the Mi 9C with competitors like Redmi Note 9 Pro or Realme 6. Ready?
Technical characteristics of the Xiaomi Mi 9C processor: disassemble by bones
The heart of the Xiaomi Mi 9C is the Qualcomm Snapdragon 720G processor, one of the most popular chipsets in the mid-segment of 2020. This processor is built on 8-nm process technology and belongs to the 700 series, which guarantees a good balance between performance and energy efficiency. But how many cores are hidden under its body?
The answer is simple: Xiaomi Mi 9C is equipped with an 8-core processor (octacor). However, not all that is clear – the cores are not the same. The architecture of the Kryo 465 involves the division into:
- 🔥 2 high-performance cores Cortex-A76 clock speed up to 2.3 GHz (for heavy tasks);
- ⚡ 6 Energy Efficient Cores Cortex-A55 1.8 GHz frequency (for background processes).
This configuration is called big.LITTLE, and allows the smartphone to automatically distribute the load: for example, when you start a game, powerful cores are used, and when watching YouTube videos – economical. This not only speeds up work, but also prolongs battery life.
💡
If you see all 8 cores loading in the Android Task Manager, that's OK! The system dynamically switches between them depending on the load.
Comparison with competitors: who is stronger in their segment?
To see how well the Mi 9C performs, compare its processor to its peers in the same price range, and the table below shows the key characteristics of chipsets that were installed in rival smartphones in 2020-2021:
| Smartphone model | Processor | Number of kernels | This frequency (GHz) | Process technology (nm) |
|---|---|---|---|---|
| Xiaomi Mi 9C | Snapdragon 720G | 8 (2+6) | 2.3 / 1.8 | 8 |
| Redmi Note 9 Pro | Snapdragon 720G | 8 (2+6) | 2.3 / 1.8 | 8 |
| Realme 6 | Mediatek Helio G90T | 8 (2+6) | 2.05 / 2.0 | 12 |
| Samsung Galaxy A51 | Exynos 9611 | 8 (4+4) | 2.3 / 1.7 | 10 |
As you can see, Mi 9C The Redmi Note 9 Pro is not inferior to the Redmi Note 9 Pro (in fact, it is the same chipset), but it wins over the Realme 6 due to the more modern process technology (8 nm vs. 12 nm). A51 Exynos 9611 loses in energy efficiency, despite similar architecture.
Performance in games and everyday tasks
8 cores are good, but how do they work in practice? Let's see what the Xiaomi Mi 9C is capable of in different scenarios:
- 🎮 Thanks to the graphics accelerator Adreno 618, the smartphone pulls PUBG Mobile on settings HDR + Ultra with stable 30-40 FPS. In Call of Duty: Mobile, you can set the graphics to the maximum, but with small drawdowns in dynamic scenes.
- 📱 Multitasking: 6 GB of RAM paired with 8 cores allows you to keep up to 10-12 applications in the background without rebooting. For example, you can simultaneously listen to music in Spotify, chat in Telegram and edit photos in Lightroom Mobile.
- 📸 Camera and Processing: The processor handles recording video in 4K@30fps and the use of real-time effects (for example, background blur in portrait mode).
But there are nuances: In the Geekbench 5, for example, the Mi 9C scores about 550-600 in the single-core test and 1,700-1,800 in the multi-core test, which is a good result for a public-sector person, but it is far from flagships like the Snapdragon 865 (with its 3,000+ points).
What do you do if the games are stacked?
The influence of the number of nuclei on autonomy
Many people mistakenly think that the more cores, the faster the battery goes down. In fact, it depends on architecture and optimization. In the Snapdragon 720G, the energy-efficient Cortex-A55 cores consume minimal energy for simple tasks (calls, messengers), and the powerful Cortex-A76 only turn on when necessary.
In the tests Xiaomi Mi 9C shows the following results:
- 🔋 Video playback (YouTube, 1080p): up to 12-14 hours with full charge;
- 📞 Conversations (3G/4G): before 20–22 hours;
- 🎮 Games (PUBG Mobile, medium settings: 4-5 hours.
By comparison, the Redmi Note 9 Pro with the same chipset but a 5020mAh battery (versus 4,000mAh for the Mi 9C) lasts 15-20% longer, but the difference is not critical thanks to the optimization of MIUI.
💡
The 8 cores in the Snapdragon 720G don’t mean high battery consumption, it all depends on which cores are involved.
How to check the number of cores on your Xiaomi Mi 9C
If you want to make sure your smartphone is actually equipped with an 8-core processor, there are a few ways to do this:
- Through Android Settings: Go to Settings → About Phone → General information; Find the CPU Model line – Qualcomm SDM720G should be specified there; For more information, install the CPU-Z app from Google Play.
- Using the AIDA64 app: 1. Download AIDA64 from Google Play; 2. Open the "CPU" section; 3. The number will be specified in the "CPU Cores" bar (8 for the Mi 9C).
☑️ Checking the processor in Xiaomi Mi 9C
Note: If there are fewer than 8 cores in the app, this may mean:
- ⚠️ Firmware problems (for example, after a failed update);
- ⚠️ Activated power saving mode, which disables part of the cores;
- ⚠️ Fake device (rarely seen, but worth checking).
💡
If AIDA64 only displays 4 cores, try restarting your smartphone or resetting to factory settings via Settings → Additional → Recovery and Reset.
