In this article we will discuss in detail which ARM-The chip is used in the Xiaomi Redmi Note 8 Pro, how its core system is designed and why this configuration has become the benchmark for the mid-range segment. We will touch on technical nuances, such as process technology and clock frequencies, which directly affect energy efficiency and heating of the case. The information will be useful both for enthusiasts planning to reflash, and ordinary users who want to know more about their device.

For starters, ARM’s architecture dominates the mobile computing world, balancing power with energy consumption. In the case of the model in question, engineers chose a solution that bypassed even some of the competitors’ flagship offerings at the time, made possible by using the then-advanced process technology and the proper distribution of tasks among the cores.

The CPU of the Xiaomi Redmi Note 8 Pro is the MediaTek Helio G90T. It's not just a set of transistors, but a complex system designed to meet the demands of mobile gamers. ARM architecture is implemented in the big.LITTLE scheme, which implies the presence of cores of different power to perform various types of tasks, this approach allows the device to remain responsive in the interface and save battery power in standby mode.

⚠️ Note: Don’t confuse the Redmi Note 8 Pro with the regular Redmi Note 8. The conventional version uses a Qualcomm Snapdragon 665 processor that has a completely different architecture and performance metrics.

Technical characteristics of the Helio G90T processor

When we look at what ARM chip is in a device, we inevitably come to the specifications of the Helio G90T. This chipset is made using TSMC's 12nm process technology, which was a very modern solution for 2019. It was the thin process technology that allowed you to fit 8 billion transistors on a chip, ensuring high density of computations. The architecture of ARM v8.2-A is at the heart of this processor, providing advanced instructions for working with artificial intelligence and improved data processing.

The graphics accelerator in this model also deserves a special mention. It uses the Mali-G76 MC4, which operates at up to 800 MHz. It is a powerful solution that, in conjunction with optimized drivers, allows you to run heavy games at high graphics settings. For comparison, many competitors at the time offered graphics at the level of Mali-G72 or Adreno 610, which were significantly inferior in performance.

An important aspect is RAM support. The processor is capable of working with LPDDR4X modules at up to 2300 MHz. This provides high channel bandwidth, which is critical for fast application loading and multitasking. In conjunction with a UFS 2.1 drive, the system demonstrates excellent reading and writing speeds.

• 🚀 Number of kernels: 8 kernels (octa-cor).
• ⚡ Clock speed: up to 2.05 GHz for powerful cores.
• 📐 Process: 12 nm FinFET.
• 🧠 Neuronucleus: built-in block AI Processing Unit.

It's worth noting that having a dedicated neural network processing unit (APU) allows the smartphone to work efficiently with machine learning algorithms, which is used in the camera for photo enhancement, in voice assistants and in augmented reality functions. The ARM architecture is constantly evolving, and the Helio G90T was one of the first mid-level chips to receive such advanced capabilities.

Configuration of the kernels: big.little in action

One of the biggest strengths of the ARM architecture in the Xiaomi Redmi Note 8 Pro is its heterogeneous computing structure, which is divided into two core clusters, each with its own characteristics and purpose, a scheme known as big.LITTLE that allows the system to dynamically switch between high performance and energy saving modes depending on the current load.

The first cluster consists of four powerful Cortex-A76 cores, which are overclocked to 2.05 GHz and are designed to perform heavy tasks. When you run a game, edit a video or work with heavy applications, the system activates this particular unit. The A76 cores are deeply pipelined and capable of executing a large number of instructions per clock, which ensures smooth interfaces.

The second cluster is represented by four energy-efficient Cortex-A55 cores operating at frequencies up to 2.0 GHz. Their task is background processes, listening to music, reading text or waiting for an incoming call. In these scenarios, using powerful cores would be impractical and would lead to rapid battery discharge. The A55 cores consume minimal amount of energy, prolonging the battery life of the device.

For maximum performance in games, enable Game Turbo mode in the Security app, which prioritizes the CPU resources for running a game.

Switching between clusters is almost instantaneous and unobtrusive to the user. If you abruptly fold the game and open the browser, the system quickly resets frequencies and switches to energy-efficient cores. Conversely, when you launch a heavy application, the Cortex-A76 cores are instantly connected, which is the main advantage of the ARM architecture in mobile devices.

Graphic subsystem and gaming capabilities

Speaking of the processor, you can't ignore the graphics accelerator, which is an integral part of the SoC (System on Chip). The Redmi Note 8 Pro has a Mali-G76 MC4 GPU. The Bifrost architecture behind it has brought significant performance gains over previous Mali generations. Four computing clusters (MC4) provide enough power for modern mobile gaming.

Support for the OpenGL ES 3.2 and Vulkan 1.1 APIs allows game developers to squeeze the most out of iron. Vulkan in particular provides lower-level hardware access, which reduces driver overhead and boosts FPS in games. For mobile gaming enthusiasts, this means a steady 60 frames per second on hits like PUBG Mobile or Call of Duty Mobile, at high graphics settings.

However, powerful graphics require good cooling. Xiaomi Redmi Note 8 Pro became the world’s first mid-range liquid-cooled smartphone. Engineers have implemented a system of copper tubes and graphite layers that effectively remove heat from the Helio G90T. Without such a cooling system, trottling (reduced frequency due to overheating) would have come much faster, negating the benefits of the ARM architecture.

⚠️ Attention: During long gaming sessions in heavy games, the smartphone body can significantly heat up at the top.This is normal for the heat sink system, but it is recommended to remove the case for better cooling.

Also worth mentioning is MediaTek's HyperEngine technology, which is a set of optimizations that manages network, display and processor resources during play, for example, if an incoming call comes in during play, the system will redistribute resources so that the connection doesn't break and the game doesn't crash, which makes the experience more stable.

Comparison with competitors and analogues

To understand the place of Xiaomi Redmi Note 8 Pro in the history of mobile technology, you need to compare it. ARM-The main rival was the Qualcomm Snapdragon 730, which was installed in many mid-range smartphones, both of which used 8-core circuits, but they had different configurations and process.

The Snapdragon 730 was built on an 8nm process, which theoretically made it more energy efficient. However, the Cortex-A76 cores in the Helio G90T were more powerful than the Kryo 470 cores (which are a modification of the Cortex-A75/A76) in the Snapdragon. In synthetic tests such as AnTuTu, the Redmi Note 8 Pro scored about 280,000 points, while competitors on the Snapdragon 730 barely reached 220,000.

• 📊 AnTuTu v8: ~280,000 points (Redmi Note 8 Pro).
• 🆚 Competitor: ~220,000 points (Snapdragon 730).
• 🔥 Heating: Higher at Helio G90T 12nm process technology.
• 🎮 GPU: Mali-G76 Adreno 618 is more powerful in certain scenarios.

In terms of pure CPU performance, MediaTek’s ARM architecture has leapt ahead. However, Snapdragon has often been praised for more stable modem performance and better camera optimization. Users have had to choose between raw power and competitive balance. Both are considered obsolete for heavy-duty products but still manage daily tasks.

The impact of architecture on autonomy and heating

The energy consumption issue is always a hot topic when discussing the ARM architecture. As mentioned earlier, the Helio G90T 12nm process is not the most advanced. The thinner norms (7 nm, 5 nm) allow more transistors to be placed in a smaller area, reducing drag and heating. Therefore, the Redmi Note 8 Pro is known for its warm temper under load.

However, the availability of energy-efficient Cortex-A55 cores saves the day-to-day use. When watching videos, reading news or using instant messengers, a smartphone can run all day without recharging. The 4,500mAh battery is perfectly combined with optimized energy consumption in the background.

System cooling is critical here. If Xiaomi's engineers hadn't implemented liquid cooling, the processor would be constantly hitting the temperature ceiling, resetting frequencies. As a result, the user would be watching friezes and lags. Thanks to competent engineering, the device is able to maintain high frequencies longer than many analogues without active cooling.

Update prospects and programme support

The architecture of the processor directly affects what versions of the operating system the device can get. Xiaomi Redmi Note 8 Pro originally came out on Android 9 Pie with a shell MIUI 10. Thanks to 4 GB (or more) of RAM and a powerful 8-core CPU, the smartphone received updates to Android 11 and MIUI 12.5. This confirms the margin of safety embedded in (iron).

However, further upgrades to Android 12 and higher have become problematic not so much because of the power of the cores as because of MediaTek's driver support policies.Chip manufacturers must provide updated binary blocks to MIUI developers, and often this process is delayed or stopped earlier than Qualcomm.So, despite the fact that the Cortex-A76 still pulls on modern interfaces, software support may be limited.

For custom firmware enthusiasts, the ARM Helio G90T architecture is of interest. The developer community is actively creating modified versions of Android that allow the device to live longer. The availability of an unlockable bootloader (in global versions) allows you to install lighter builds that work faster than stock.

⚠️ Warning: Unlocking the bootloader and installing custom firmware resets the warranty and can lead to data loss.
