How to find out the processor architecture on Xiaomi: ARM7, ARM64 or x86?

Have you ever wondered why some apps on your Xiaomi run faster and others fail or fail? It could be because of the processor architecture: ARM (including ARM7/ARMv7 and ARM64/ARMv8) or x86. It depends on firmware, emulators and even game performance. But how do you know which chip is on your device?

In this article, we’ll break down all the working methods, from simple (via phone settings) to advanced (using ADB and specialized utilities), you’ll also learn why Xiaomi almost never uses x86 in smartphones, but sometimes occurs in tablets, and how this affects the choice of custom firmware. Don’t worry: no complicated manipulations, only clear instructions with examples for popular models such as the Redmi Note 12, POCO X5 or Mi Pad 5.

Why it’s important to know the processor architecture on Xiaomi

The processor architecture is the language that hardware and software communicate with.

• 🔧 Compatible with firmware. ROM (For example, LineageOS or Pixel Experience are built for specific architectures. ARM64 on ARMv7 lead to the brick».
• 🎮 Emulator work. BlueStacks or MuMu are optimized for x86, on ARM may or may not be stopped.
• 📦 Install applications. Some of them APK (For example, for Windows applications through WSA) demand x86.
• 🔄 Updates MIUI. Xiaomi sometimes shares architecture updates (for example, for the Mi Pad 4 with the new model). x86 and ARM).

By 2026, 99% of Xiaomi smartphones are used ARM-processors (mainly processors) ARM64), x86 It is only found on individual tablets (e.g. Mi Pad 4) and laptops (Mi Notebook), but even then it is important to confirm the architecture before installing the software.

Method 1: Checking through phone settings (without apps)

The fastest method is to view the information in the Settings menu. It works on all Xiaomi devices with MIUI (including Redmi, POCO, Black Shark):

1. Open the Settings. → The phone.
2. Tap the MIUI version several times until the message “You are a developer!” appears (unless the developer mode is activated).
3. Return to the main Settings menu and select Additional → For Developers.
4. Scroll down to the Hardware block and find the CPU Architecture or Instruction Set string.

Possible values:

• armv7l or armeabi-v7a → ARM32 (ARMv7).
• aarch64 or arm64-v8a → ARM64 (ARMv8).
• x86 or x86_64 → x86 (32-bit x86_64 (64-bit).

💡

If there is no "CPU Architecture" option, try another method or upgrade MIUI to the latest version.

Method 2: Applications (AIDA64, CPU-Z, DevCheck)

If the standard settings don't show the architecture, third-party utilities will come to the rescue, and we recommend three proven applications:

How to use (in the example of AIDA64):

1. Install the app from Google Play.
2. Open the CPU section (CPU).
3. Find the Instruction Set or Instruction Set.

Install AIDA64 Google Play|Open the section “CPC"|Find the line "Set of instructions"|Contrast the value with the table above-->

⚠️ Note: Some applications (e.g. AnTuTu Benchmark) can only show a CPU model (e.g. Snapdragon 8 Gen 2) but not its architecture. CPU-Z.

Method 3: ADB commands for power users

If you have access to ADB (for example, through a computer), you can learn the architecture with a single command, which is suitable for devices with an unlocked bootloader or USB debugging enabled.

Instructions:

1. Connect Xiaomi to your PC and activate USB Debugging in Settings → For Developers.
2. Open the command prompt (Windows) or terminal (Linux/macOS) and type:

adb shell getprop ro.product.cpu.abi

Possible answers:

• armeabi-v7a → ARMv7 (32-bit)
• arm64-v8a → ARM64 (64-bit)
• x86 or x86_64 → x86.

For more detailed information, use:

adb shell cat /proc/cpuinfo

In the output, find the Processor string, which will indicate the exact architecture (for example, ARMv8 Processor rev 4).

Method 4: Processor model analysis (via specifications)

If none of the above methods worked, you can define the architecture by the model of the chipset. all processors Qualcomm Snapdragon, MediaTek Helio/Dimensity and Xiaomi Surge are built on ARM.

• 📱 All Xiaomi models (including Redmi, POCO, Black Shark is being used ARM (usually ARM64).
• 🖥️ Tablets: Mi Pad 4 (model M1806D9E) squash x86 (Intel Core m3-8100Y).
• 💻 Laptops: Mi Notebook line uses x86_64 (Intel Core processors or AMD Ryzen).

To find out the chipset model:

1. Open Settings → About the phone → Full specs.
2. Find the processor or the SoC model.
3. Check the chipset specifications on the manufacturer’s website (e.g. [qualcomm.com](https://www.qualcomm.com) for Snapdragon).

Frequent Mistakes and How to Avoid Them

When defining architecture, users often encounter misunderstandings, and here are the most common ones:

⚠️ Attention: If the application shows aarch64, This does not mean that your device supports only 64-bit applications. ARM64-processors (e.g. Snapdragon 8 Gen 3) are backward compatible with 32-bit code (ARMv7).

• ❌ Confusion with rank: ARM64 ≠ 64-bit OS. Even on the ARM64-device MIUI Can be used in 32-bit mode for compatibility.
• ❌ Trust the antutum: AnTuTu Benchmark shows a model of the processor, but not its architecture. CPU-Z.
• ❌ Ignoring. x86 In tablets: Mi Pad 4 c x86 It is not compatible with most customized firmware for ARM.

If in doubt, check the official model specifications on Xiaomi’s website or forums (4PDA, XDA Developers, for example, for POCO F5 (Snapdragon chipset 7+ Gen 2) architecture ARM64, A for Mi Pad. 4 — x86_64.

💡

If your Xiaomi device is released after 2018, there is a 99% chance it has an ARM64 architecture. x86 is only found in tablets (Mi Pad 4) and laptops.
