Xiaomi 9T (also known as the Redmi K20 In some regions, it is one of the most popular mid-range smartphones of 2019, and its success was not only due to its stylish design and its high-end mobile phone. AMOLED-The screen, but also a powerful “stuffing” that can compete with flagships. the Central question that worries many users before buying or after purchasing: what processor is in Xiaomi 9T and what he's capable of?
In this article, we will take a closer look at the chipset’s specifications, architecture, and competition (including the Snapdragon 730 and Kirin 810), and answer questions about gaming performance, multitasking and energy efficiency. If you’re planning to buy a Xiaomi 9T bpd or just want to make the most of your device, this information will be useful.
What processor is installed in Xiaomi 9T: official data
Xiaomi 9T uses Qualcomm Snapdragon 730 processor (codename sm7150). This is an 8-core mid-level chipset, released in April 2019 on the 8-nanometer process technology Samsung LPP. It became a logical continuation of the Snapdragon 700 line and was positioned as an alternative to flagship solutions for devices with a price of up to 40,000 rubles.
Key features of the Snapdragon 730:
- 🔹 Architecture: 2 high-performance Kryo 470 Gold cores (based on the Cortex-A76) 2.2 GHz + 6 energy efficient Kryo 470 Silver cores (based on the Cortex-A55) frequency up to 1.8 GHz.
- 🎮 Graphics: Adreno 618 video accelerator with support for Vulkan 1.1, OpenGL ES 3.2 and hardware acceleration for gaming.
- 📱 Display support: resolution up to 3360×1440 (QHD+) and frequency of update to 90 Hz (although in Xiaomi) 9T used 60 Hz).
- 📡 Modem: Snapdragon X15 LTE Support for speeds up to 800 Mbps (Cat. 15) and Dual 4G VoLTE.
Fun fact: The Snapdragon 730 was the first in the 700-series chipset to feature a neural processor (NPU) to speed up artificial intelligence tasks, improving photo processing, voice recognition and Google Assistant.
Snapdragon 730 Comparison with Competitors: Who is Stronger?
In 2019-2020, the Snapdragon 730 competed with several popular chipsets. Let’s compare it with the main rivals in the table:
| Characteristics | Snapdragon 730 | Snapdragon 730G | Kirin 810 | Mediatek Helio G90T |
|---|---|---|---|---|
| Technique | 8 nm (Samsung LPP) | 8 nm (Samsung LPP) | 7 nm (TSMC) | 12 nm (TSMC) |
| CPU (max frequency) | 2×2.2 GHz + 6×1.8 GHz | 2×2.2 GHz + 6×1.8 GHz | 2×2.27 GHz + 6×1.88 GHz | 2×2.05 GHz + 6×2.0 GHz |
| GPU | Adreno 618 | Adreno 618 (accelerated by 15%) | Mali-G52 MP6 | Mali-G76 MP4 |
| AnTuTu (Grade Average) | ~250 000 | ~270 000 | ~280 000 | ~220 000 |
| Support for 5G support | ❌ No. | ❌ No. | ❌ No. | ❌ No. |
And you can see from the table that the Snapdragon 730 is inferior to the Kirin 810 in synthetic tests, but it's superior in energy efficiency because of its more advanced process technology. G90T, Despite the marketing focus on gaming opportunities, it loses both in performance and energy consumption.
⚠️ Note: If you choose between Xiaomi 9T (Snapdragon 730 and Huawei Nova 5T (Kirin 810), note that Kirin warms up more strongly under prolonged loads. Tests show that the Snapdragon 730 holds frequencies more stable under load.
Game Performance: Will Genshin Impact and PUBG pull?
One of the key questions owners Xiaomi 9T is gaming performance. Let's understand what settings can be expected in popular games:
- 🎮 PUBG Mobile: stable 40 FPS setting HDR + Ultra (without antialiasing) When turned on 90 FPS (If available, the graphics quality will have to be reduced to Smooth.
- 🏰 Genshin Impact: 30 FPS Medium with rare drawdowns up to 25 FPS In the open world, the Low ones are stable 60. FPS.
- 🏎️ Asphalt 9: maximum settings (Ultra) with rare slowdowns in loaded scenes.
- 💥 Call of Duty: Mobile: 60 FPS Very high settings without any problems.
To improve the gaming experience, it is recommended:
- Disable background apps (especially Facebook and Instagram).
- Activate Performance Mode in Settings → Battery → Performance Modes.
- Use Game Turbo (built-in software from Xiaomi for game optimization).

Importantly, Adreno 618 supports the Vulkan API, which allows some games (such as Minecraft) to run faster, but in heavy projects like Genshin Impact, the chipset starts to warm up, and after 20-30 minutes, the frequencies can decrease (trottling).

Benchmark: real tests of the Snapdragon 730 in Xiaomi 9T
To objectively assess performance, we turn to the results of popular benchmarks. Below are the average values for Xiaomi 9T (6/128 GB) on MIUI 12.5:
- 📊 AnTuTu 9: ~250,000 points (for comparison, the Snapdragon 845 scores) ~300 000).
- 🔧 Geekbench 5 (Single-Core): ~530 points.
- 🔧 Geekbench 5 (Multi-Core): ~1,700 points.
- 🎨 3DMark (Sling Shot Extreme): ~3,200 points (OpenGL) ES 3.1).
For clarity, compare with other devices:
| Device (chipset) | AnTuTu | Geekbench (Multi) | 3DMark |
|---|---|---|---|
| Xiaomi 9T (SD 730) | 250 000 | 1 700 | 3 200 |
| Realme X2 (SD 730G) | 270 000 | 1 800 | 3 500 |

💡
The Snapdragon 730 in the Xiaomi 9T shows better energy efficiency than the Kirin 810, which has a positive effect on battery life.
Energy Efficiency and Heat: Snapdragon 730 Weaknesses?
Despite its advantages, the Snapdragon 730 has two controversial issues: heating and power consumption at peak loads.
Heating:
- 🔥 In games (such as Genshin Impact), the processor temperature can reach 70-80.°C, which leads to trottling.
- ☀️ In everyday tasks (social networks, video) the heating rarely exceeds 45-50.°C.
- ❄️ Solution: Use heat sink cases or play at ambient temperatures below 25°C.
Autonomy: Xiaomi 9T is equipped with a battery of 4000 mAh. in tests at mixed load (60 Hz screen, 50% brightness, 4G) the device shows:
- 📱 Screen: 6-7 hours of active use.
- 🎮 Games: 3.5-4 hours (PUBG Mobile on Medium Settings).
- 📺 Video: Up to 12 hours of playback (YouTube, 1080p).
⚠️ Attention: If your Xiaomi 9T discharge faster than above, check the settings → Battery → Battery use. Often the culprits are apps like Facebook or TikTok, which run in the background and consume up to 20 percent of the charge.
To improve autonomy:
- Turn off Permanent Network Search in Wi-Fi settings.
- Use dark themes (AMOLED-screen saves charge).
- Limit the background activity of applications through Settings → Apps → Permissions → Auto Run.
💡
If your smartphone is hot in games, try lowering the screen resolution to 720p in the developer settings (Settings → About Phone → MIUI version – tap 7 times).
