Why the processor is important for a smart TV
Choosing a Xiaomi Mi TV TV 4X And it's often accompanied by questions about the stuffing, especially the processor, and it's a component that not only determines the speed of the interface, but also the multimedia capabilities: smooth playback. 4K-contents HDR, Unlike smartphones, where processors are updated annually, in TVs, chips last for years, so their performance is critical for long-term use.
Xiaomi used several processor modifications in the Mi TV 4X lineup depending on the diagonal and year of release. For example, the 2018-2019 models were equipped with Amlogic chips, and later versions were equipped with MediaTek solutions. It is important to understand these nuances if you are planning to buy a used TV or want to assess the prospects for updating the firmware. Next, we will analyze in detail what processors were installed in the Xiaomi 4X, their architecture and how they affect the user experience.
What processors were installed in Xiaomi Mi TV 4X: the full list
The Mi TV 4X range includes models with diagonals from 43 to 65 inches, released between 2018 and 2021, and processors vary depending on the modification and market (for example, for China and global versions).
- 🔹 Amlogic T962 — base variant for 2018-2019 models (43, 50, 55) Cortex-A53 clockwise.
- 🔹 Amlogic T972 — improved version for 2019-2020 models (55, 65) Cortex-A55 Support for Dolby Vision and improved video dekoderom.
- 🔹 MediaTek MT9611 — flagship chip for versions 2020–2021 year-end (55", 65"). Four-core. Cortex-A73/A53 in the big.little configuration, frequency to 1.5 GHz.
- 🔹 MediaTek MT9602 — Budget option for 2021 models (43, 50) Cortex-A53, optimized for energy efficiency.
Note that global versions (e.g. Europe) often featured the Amlogic T972, while Chinese versions featured the MediaTek MT9611, due to differences in certification requirements and support for streaming services (e.g. Netflix 4K requires hardware features).
Technical characteristics of processors: comparative table
To make an objective assessment of each chip’s capabilities, we compare the core architecture, graphics accelerator, codec support, and power consumption, and we can see how much the TV can do today’s tasks, such as playing video in 4K@60fps or working with heavy-duty applications like Kodi.
| Processor model | CPU architecture | Graphic accelerator | Support for HDR | Max, permission. | Energy consumption (W) |
|---|---|---|---|---|---|
| Amlogic T962 | 4× Cortex-A53 @1.5 GHz | Mali-450 MP3 | HDR10, HLG | 4K@30fps | 8–12 |
| Amlogic T972 | 4× Cortex-A55 @1.5 GHz | Mali-G31 MP2 | HDR10+, Dolby Vision | 4K@60fps | 10–14 |
| MediaTek MT9611 | 2× Cortex-A73 + 2× Cortex-A53 | ARM Mali-G52 | HDR10+, Dolby Vision | 4K@60fps | 12–16 |
| MediaTek MT9602 | 4× Cortex-A53 @1.3 GHz | ARM Mali-470 MP3 | HDR10 | 4K@30fps | 6–10 |
The table shows that MediaTek MT9611 It's a great hybrid architecture, big.LITTLE, which allows for better multitasking. T972 More energy efficient when reproducing HDR-If you're interested in Dolby Vision support, look at models with these two chips, which are budget versions (like those with a Dolby Vision). MT9602) It might not be.

How the processor affects the performance of Xiaomi Mi TV 4X
The performance of an Android TV is not only hardware-based, but also firmware optimization, but the processor plays a key role in the following scenarios:
- 🎮 Games and emulators: chips with graphics accelerator Mali-G52 (for example, MT9611) Better handle games from Google Play or retro console emulators (for example, PPSSPP).
- 📺 streaming 4K: For smooth reproduction 4K@60fps YouTube or Netflix needs support VP9 Profile 2 and HEVC, which are only T972 and MT9611.
- 🔄 Multitasking: TVs with Cortex-A73 (like MT9611) switch between applications faster and less often “hang” when opening heavy widgets.
- 🔊 Sound processing: Processors with Dolby Atmos support (e.g., Dolby Atmos, MT9611) They work better with external sound systems.
In practice, the difference between chips is noticeable when you're in heavy use, like if you run Kodi with network storage and stream video in the same way. 4K, Amlogic T962 It can start to slow down, but MediaTek can start to slow down. MT9611 It's not a problem, but for basic viewing. TV-channels or movies in full HD the difference will be minimal.
What to do if the TV is slowing down?
Comparison with competitors: how Xiaomi 4X looks on the background of other Smart TVs
To assess how competitive the processors in the Mi TV 4X are, compare them to chips in TVs of the same price segment (2018-2021) from other brands:
- 📺 Samsung Crystal UHD (2020: Uses a Crystal processor 4K (exclusive development of Samsung with quad-core CPU and Mali-G52. In terms of performance comparable to MediaTek MT9611, It is better optimized for Tizen. OS.
- 📺 LG UK6200 (2019: Equipped with Alpha 7 Gen 2 chip with quad-core CPU graphical Mali-470. Xiaomi is losing. 4X supportive HDR, But it benefits from energy efficiency.
- 📺 TCL 55P8 (2021: Uses MediaTek MT9612 — improved MT9611 supportive AV1 higher-frequency GPU. Exceeding Xiaomi 4X Decoding video, but it is more expensive.
The main advantage of Xiaomi Mi TV 4X is the ratio of price to opportunity. TVs with MediaTek MT9611 performance is close to the flagships of Samsung and LG, but they are 20-30% cheaper. However, they also have weaknesses: for example, PatchWall firmware (in Indian versions) can slow down even on top chips due to poor optimization.
💡
If you need a TV for streaming 4K Games and games – choose models from MediaTek MT9611. Amlogic is also suitable for basic use. T972.
Frequent Processor Problems and How to Solve Them
Even the most reliable chips can face software or hardware problems, and here are the typical CPU-related symptoms in the Xiaomi Mi TV 4X and how to fix them:
⚠️ Warning: If the TV overheats and turns off after 10-15 minutes of operation, this may indicate a malfunction of the cooling system (for example, dried thermopaste.
- 🔄 Halts when starting applications: Most often caused by RAM overload. Close background processes through Settings → Annexes → Launched.
- 📉 Reproduction lags 4K: Check if your chip supports you. VP9 Profile 2 (see table above). If not, lower the resolution to 1080p.
- 🔌 TV not turning on: Power supply may malfunction, but sometimes it's the fault of the "hang" processor. Try to turn off power for 1 minute, then hold the power button for 10 seconds.
- 🔊 No sound in some applications: This may be due to codec incompatibility. Update the firmware or install an alternative player (e.g, VLC).
If the problems are systemic (for example, the TV is constantly restarting), try resetting to the factory settings.
- Go to Settings → Device → Reset settings.
- Choose to erase all data and confirm.
- After restarting, reset the TV.
☑️ Diagnostics of Processor Problems
How to check the processor in your Xiaomi Mi TV 4X
If you're not sure what chip is installed in your TV, you can identify it in a number of ways, and the simplest is through the settings menu.
- Open the settings (cog on the remote).
- Go to the section About TV or About the device.
- Find the Model and Processor lines (some firmware may display as a SoC or Chipset).
If the menu does not contain information about the processor, you can use third-party applications:
- 📱 Install. AIDA64 or CPU Google Play Identifier (requires a remote with Google Assistant or mouse).
- 💻 Connect the TV to the PC on ADB And then you run the command: adb shell cat. /proc/cpuinfo The output will indicate the processor model.
For models with MediaTek, you will see a string like MT9611 in the cpuinfo output, and for Amlogic, Meson T972. If you want more detailed information (such as core frequency), use the command:
adb shell cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
