How to know exactly which processor is installed on Xiaomi Redmi Note 4

Owners of the popular Xiaomi Redmi Note 4 smartphone often face the need to pinpoint the model of the installed processor, which is critical for enthusiasts planning to install custom firmware, unlock the bootloader or just want to understand the real capabilities of their device, the fact that this device was released in two completely different versions, which are significantly different in performance and energy efficiency.

The main confusion arises from the fact that the devices are visually identical, but under the hood they can have chips from different manufacturers. The global version is most often based on the Snapdragon 625 platform, while the Chinese variation (Global China) is often equipped with MediaTek Helio X20.

In this article, we will take a look at all the ways you can identify the heart of your smartphone, how to use embedded system tools, third-party diagnostic tools, and even special engineering codes, and why this information is important for the stable operation of your gadget in the long run.

Why it is important to know the exact processor model

The first thing Xiaomi users need to realize is the fundamental difference in the architecture of the processors. Snapdragon 625 is made on 14-nm process technology, which provides excellent power consumption and low heating. In turn, the Helio X20 uses 20 nm norms and has a more complex but less efficient circuit of ten cores. A definition error can lead to the installation of incompatible Recovery or firmware.

Locking the bootloader and obtaining superuser (Root) rights are also directly platform-dependent.The hacking techniques for Qualcomm chips often don't work on MediaTek devices, and vice versa.If you try to apply the Snapdragon tool on a Helio device, there's a high risk of turning the phone into a brick.

⚠️ Warning: Never flash images designed for another platform, even if the phone model name is the same, guaranteed to render the device inoperable without software recovery.

Also, knowing the processor helps you understand how your system behaves in games and heavy applications. If your phone suddenly brakes or discharges quickly, comparing your chip’s performance to benchmarks can help you identify hardware limitations or defects.

Checking through the About Phone menu in MIUI

The easiest and most accessible way to get the initial information is to look at the standard operating system settings. However, the MIUI shell interface sometimes hides the detail, showing only the general name of the series.

Next, look for the phone, which is usually at the top of the list. The "processor" or "CPU" line may show a label. For example, you may see the words Octa-core or a specific frequency. But often it just says MSM8953 (for Snapdragon) or MT6797 (for MediaTek) if the system doesn't hide that data.

In some versions of firmware, especially in the early stages of the update, information can be encrypted or replaced with a marketing name. If you only see a frequency, for example, "2.0 GHz", this is not enough, in which case you need to click several times on the line MIUI version or Android version to activate the hidden menu, although on Redmi Note 4 this trick does not always work.

💡

If the About Phone menu only lists the frequency, not the chip model, this is the first sign that you need to use third-party utilities for accurate diagnosis.

Use of third-party applications for diagnosis

The most reliable method, which gives 100% guarantee of correct results, is the installation of specialized software, these programs read data directly from the hardware registry, bypassing possible software masking of the MIUI shell.

One of the most popular utilities is AIDA64. After installing and running the application, go to the CPU section. Here you will see the full model name. For the global version, this will be Qualcomm Snapdragon 625, and for the Chinese version, it will be MediaTek Helio X20. The application will also show the current frequency of each core and the temperature in real time.

Another great option is CPU-Z. It provides similar information, but in a more compact form. The Device tab in the Model field often shows the platform codename. Also note the number of cores: Snapdragon has 8 identical cores, and Helio X20 has 10 cores divided into three clusters.

• 📱 Download. AIDA64 or CPU-Z From the official Google Play store.
• 🔍 Launch the application and wait for data collection (usually) 2-3 seconds).
• 📝 Write down the exact name of the SoC (System on Chip) to search for firmware.
• 🔄 Compare the data with the compatibility table below.

Differences between the Snapdragon 625 and the Helio X20

To make sure that the data is correct, you need to know the key features of two possible platforms: the Snapdragon 625 is famous for its stability. It's an eight-core chip where all the cores work at the same frequency, which ensures smooth load distribution.

The Helio X20 uses Tri-Cluster technology. It has two high-performance cores, four medium-sized cores and four energy-efficient ones. In theory, this should give you power gains, but in practice, the Redmi Note 4 with this processor often suffers from rapid discharge and heating under intense load.

Visually, you can't tell the version by the box or the body's appearance. However, if you look at the back cover (in some regions), the Chinese version might have the MI logo with the 10 Core badge or the Helio label. The global version usually has the Snapdragon marking or just the Xiaomi logo.

Engineering menus and hidden codes

For a deeper analysis, you can use the engineering menu built into the Android shell. This method does not require the installation of additional applications, but requires careful input commands. Open the Phone application.

Enter the code ##4636##. If the system supports this request, the Testing menu will open. Select Phone information. Here, the Device information section can provide more detailed information about the radio module and the processor, although often the data is presented as codes.

There is also code ##6484## that opens the full CIT (Customer Integration Test) engineering menu. Going to Version Information, you can find a Hardware or Board string. The code name of the board often includes a hint: msm8953 will point to Snapdragon and mt6797 will point to MediaTek.

⚠️ Note: In the engineering menu, do not change the parameters unless you know exactly what they are responsible for. resetting the calibration of sensors or radio module can disrupt communication or GPS.

Analysis through Computer Connection (ADB)

For advanced users who are preparing a device for flashing, the ideal option is to check through debugging over USB.This method eliminates any software distortion, since the data is read directly from the bootloader or kernel of the system.

To start, activate Developer Mode. Go to Settings → About Phone and quickly click on MIUI Version seven times. After the “You’ve Been a Developer” notification appears, go to Advanced Settings → For Developers and enable USB Debugging.

Connect your phone to a PC with ADB Driver installed. Open the command line on your computer and type in the command:

adb shell cat /proc/cpuinfo

You'll get a detailed list of CPU characteristics, look for the Hardware string or model name. For Snapdragon, it'll be Qualcomm Technologies, Inc. MSM8953, and for MediaTek, it'll be MT6797, which is the most reliable way to verify.

💡

The ADB cat /proc/cpuinfo command provides the most accurate and technically accurate information about the iron, ignoring any cosmetic changes to the MIUI interface.
