This is due to the optimization of power consumption and heat generation. You can specify the exact modification of the chipset through the service menu of the TV (about this in one of the following sections).
MediaTek MT9611 vs Amlogic T962: Comparison of processors
The two main chipsets used in the Xiaomi Mi TV 4S – MediaTek MT9611 and Amlogic T962 – are budget, but have key differences.
- 🔹 Architecture of nuclei: MT9611 built on more modern cores Cortex-A55 (2018, while T962 use outmoded Cortex-A53 (2014: This affects energy efficiency and support for new codecs.
- 🎮 Graphic accelerator: Mali-G52 MP2 into MT9611 nearly 2 times more powerful Mali-450 MP3 into T962, What is critical for smooth interface and games (if supported).
- 📶 Support for formats: MT9611 Supports hardware decoding AV1, VP9 Profile 2 and HDR10+, then T962 limited H.265 basic HDR10.
- 🔥 Heat generation: Amlogic T962 heats up more because of less optimized 28-nm process technology (vs. 12-nm y) MT9611).
Critical: TVs with the Amlogic T962 (32′′ version) do not support official Android TV updates above version 9.0, while models on the MT9611 receive updates to Android 11.This means that over time the 32-inch model may lose compatibility with new apps (for example, YouTube or Netflix).
⚠️ Note: If you plan to use a TV for streaming in high resolution (4K HDR), Avoid models on Amlogic T962. They are physically unable to decode some modern formats without artifacts.
How to find out the exact model of the processor in your Xiaomi TV 4S
If you're not sure which chipset is installed on your TV, it can be identified in a number of ways, the most reliable is through a service menu or third-party apps.
- Open the settings → About TV → The version of the software.
- Click 5 times in a row on the line with the build number (for example, MIUI TV 1.9.65).
- In the developer menu that appears, select System Information.
- Scroll down to the Hardware section, where the processor model will be listed.
An alternative method is to use the AIDA64 app (available on Google Play for Android TV):
Install. AIDA64 Google Play|Open the app and wait for the scan.|Go to the "CP" section"|Check the line "CPU model"|Compare the data with the table above-->
If none of these methods worked, you can use the physical marking on the board.
- Turn off the TV.
- Remove the back cover (a cross screwdriver will be required).
- Find a large chip labeled MT9611 or T962 next to the radiator.
⚠️ Warning: Disassembling the TV will void the warranty. If the device is warranty, use only software verification methods.

The Impact of the Processor on Performance: Tests and benchmarks
To assess the real performance of Xiaomi Mi TV 4S chipsets, we analyzed benchmarks (including Antutu TV and Geekbench) and user tests.
- 📊 Antutu TV: MT9611 (43"/55"/65"): ~35 000–40 000 score T962 (32"): ~18 000–22 000 score
- 🎯 Real Tests: Netflix's Launch in the World 4K HDR: MT9611 lagless, T962 — It's slowing down at a high bitrate. T962 You can see the slowdown when you scroll through the lists. Games (for example, Asphalt 9): MT9611 mid-size, T962 — only at the minimum.
Interesting fact: in tests of upscale (scale Full HD to 4K), MediaTek MT9611 performed better than some of the chipsets of competitors (for example, Realtek RTD2893 on TCL TVs). However, when viewing content with low bitrate (for example, YouTube 1080p60), the difference between MT9611 and T962 is minimal.
💡
If your TV on the Amlogic T962 is slowing down when watching 4K, try manually limiting the output resolution in the source settings (for example, consoles or PC) to 1920×1080.
Can I replace the processor in Xiaomi Mi TV 4S?
Technically, it is possible to replace the processor in the TV, but in practice it is:
- ⚠️ Unprofitable: the cost of work and a new chipset will exceed the price of the TV.
- 🔧 Difficult: rations required BGA-chips (special equipment and skills).
- ⚡ Risky: High chance of damage to the board when overheating.
- 📉 It makes no sense: even after the replacement, there will be restrictions on RAM and firmware.
The only legitimate case for interference is flashing (if the processor is working properly but is not working properly due to software errors). For example, some users successfully "reanimate" the Mi TV 4S 32" on the Amlogic T962 by installing custom firmware based on CoreELEC (lightweight OS for media centers).
- Speed up the interface.
- Add support for new codecs (e.g. AV1).
- Use alternative launchers (e.g. ATV Launcher).
⚠️ Warning: Flashing on unofficial software deprives the TV of warranty and can lead to "bricking" (complete inoperability).Be sure to create a backup of the original firmware through the system before the procedure. USB Burning Tool.
💡
Replacing the processor in the Xiaomi Mi TV 4S is not economically feasible; it is better to consider buying a new model (for example, Xiaomi TV A2 or Redmi Smart TV X) with a more modern chipset.
Comparison with competitors: who is better?
To see how good the processor is in the Xiaomi Mi TV 4S, compare it to chipsets of TVs of the same price segment (2020-2023):
