The question of which video accelerator is installed in the popular budget smartphone Xiaomi Redmi 9, often arises for users who want to squeeze the most out of their device or understand the reasons for performance in games. Graphics chip is a critical component responsible not only for rendering the interface, but also for processing three-dimensional graphics in applications. Understanding the architecture of your GPU allows you to better approach the configuration of the system and the selection of game projects.
In this model, the Chinese manufacturer solution from the company Imagination Technologies, which is a somewhat unexpected step for a segment dominated by Adreno from Qualcomm or Mali from ARM. The power of the video core directly affects how smoothly the animations in the MIUI shell will work and what level of detail is available in modern mobile games.
Many users confuse the number of CPU cores with the power of graphics, but these are different entities. Redmi 9 uses the PowerVR GE8320 GPU, which operates at up to 800 MHz, which is the standard display for the budget class of 2020 release. Let's go through in detail the technical features, the impact on gameplay and the software optimization of this component.
Technical characteristics of the graphic core
The centerpiece of the graphics subsystem in Xiaomi Redmi 9 is the PowerVR GE8320 chip, which is based on the Rogue architecture, which is known for its energy efficiency but is inferior to the flagship solutions for high-poly rendering tasks. The smartphone processor, MediaTek Helio G80, integrates this graphics accelerator, providing basic performance for everyday tasks.
The frequency performance is up to 800 MHz, which allows you to process the standard Android interface without visible delays. However, when you move to heavy three-dimensional scenes, the performance margin is quickly exhausted. The GPU architecture supports modern APIs such as OpenGL ES 3.2, OpenCL 2.0 and Vulkan 1.1, which theoretically opens up access to a wide range of applications.
⚠️ Note: Don’t expect to get a PowerVR GE8320 The performance of the flagship Snapdragon 865-level solutions is a budget core optimized for battery saving, not benchmark records.
It's worth noting that video decoding is supported: the video accelerator is capable of streaming video at 1080p at 60 frames per second, which fully covers the capabilities of the built-in display. There are plenty of resources to watch content from YouTube or Netflix, but encoding video in-house will be slow.
💡
For maximum gaming performance, always close your background apps before you start, as the 3GB or 4GB of RAM in Redmi 9 quickly fills up with the system cache.
Performance in Games and Benchmarks
The real performance of the PowerVR GE8320 is best seen in game scenarios. In synthetic tests like AnTuTu or 3DMark, the smartphone scores high in the lower market segment, meaning that complex shader effects and high-resolution textures will be given to the device hard.
Let’s look at the behavior of the device in popular projects:
- 🎮 PUBG Mobile: The game runs on the minimum graphics settings ("Smooth") with a frame rate of about 25-30 FPS. Set the regimen on"HD" Not recommended due to severe downsizing.
- 🏎️ Asphalt 9: Legends: Requires lower rendering resolution. Micro-freezes are possible in medium settings for intense collisions.
- ⚔️ Genshin Impact: Launch is only possible on minimum settings (30) FPS, Long-term play results in noticeable heating of the body and trolling.
- 🏃 Call of Duty: Mobile: Shows the most stable result among shooters, allowing you to play comfortably at low graphics settings.
It's important to understand that heat is a limiting factor, and when you're under a lot of stress, the system lowers the frequencies of the CPU and the graphics core to avoid overheating, and this phenomenon, known as trottling, causes you to fall. FPS through 15-20 play-off.
Comparison with competitors and predecessors
To understand the Xiaomi Redmi 9’s place in the device hierarchy, it’s useful to compare its GPU to rivals from the same period. The main rivals were Snapdragon 665-based devices with Adreno 610 graphics. Despite the similar class, Adreno drivers often show better optimization in games.
Below is a comparative table of performance of graphics subsystems in the budget segment:
| Smartphone model | Graphics Processor (GPU) | Frequency (MHz) | 3DMark Wild Life Assessment |
|---|---|---|---|
| Xiaomi Redmi 9 | PowerVR GE8320 | 800 | ~350 points |
| Realme 6 | Mali-G52 MC2 | 950 | ~420 points |
| Samsung Galaxy A11 | Adreno 506 | 650 | ~280 points |
| Xiaomi Redmi Note 8 | Adreno 610 | 600 | ~400 points |
As the data shows, the PowerVR GE8320 is roughly in the middle, ahead of the older Adreno solutions but slightly behind the newer Mali cores. However, in real life, the difference of 10-15% on benchmarks may not be as noticeable as the quality of driver optimization by a developer.
The predecessor of Redmi 8 used Adreno 506, which was much weaker, so the switch to Redmi 9 gave a noticeable increase in graphics power, especially in support of modern versions of the API, which allowed to run games that in the previous generation could not open.
Features of drivers and updates
One of the key problems with budget devices powered by MediaTek is the rare update of graphics drivers. Unlike the Qualcomm ecosystem, where GPU drivers can be updated through the Google Play Store, owners of Redmi 9 depend on firmware updates from Xiaomi.
Xiaomi releases security updates and bug fixes that can affect the stability of the GPU. However, a dramatic increase in performance is not expected. Optimizing MIUI sometimes leads to the opposite effect: new versions of the shell can consume more resources, loading an already modest video accelerator.
⚠️ Note: Installation of third-party graphics drivers or modified firmware (Custom) ROM) This can lead to system instability and loss of warranty.
Users who have installed custom firmware (like LineageOS or Pixel Experience) often report different performance, which is because different assemblers adjust the frequencies and power limits for PowerVRs differently. Stock firmware prioritizes autonomy, while customs can be more aggressive in overclocking.
Can I update the GPU driver separately?
Methods of software optimization
Despite hardware limitations, there are a number of software methods to improve interface responsiveness and FPS stability. The first step is to use built-in MIUI tools. The Security app contains the Game Turbo section, which redistributes CPU resources in favor of running a game.
Developer mode is available for more advanced users, and you can activate it by quickly clicking 7 times on the MIUI version in the About Phone menu. In the Extended Settings -> For developers, you can find useful options:
- 📉 The scale of animation: Reducing the value to 0.5x visually accelerate the operation of the interface, reducing the load on the rendering of transitions.
- 🚫 Background Processes: Limiting the number of background processes will free up RAM for game textures.
- 🎨 4x MSAA: Including smoothing in some games can improve the picture, but on Redmi 9 it will reduce the performance, so experiment carefully.
Also worth mentioning is the MEMC (Motion Estimation, Motion Compensation) feature, which is used in some Xiaomi TVs and smartphones to interpolate frames. In Redmi 9, software algorithms to improve video streaming may not work correctly with some players, causing artifacts. If you notice strange video behavior, try turning off image enhancements in the video player settings.
☑️ Optimizing Redmi 9 for gaming
The Effects of Temperature on GPU Operation
Heat mode is the Achilles heel of budget smartphones. The Redmi 9 is made of plastic, which is worse at removing heat than metal or glass. When heated above a certain temperature (usually 40-42 ° C on the surface), the protective mechanism comes into effect.
Trottling happens in a step-by-step fashion, first the brightness of the screen drops, then the frequency of the processor decreases, and last of all the graphics core, which causes smooth play to suddenly turn into a slideshow. Using an external cooler for a smartphone can significantly extend the time of comfortable play at high settings.
Long-term use at high temperatures has a negative impact not only on performance, but also on battery status. Lithium-ion battery degrades faster if the phone regularly heats up while charging or playing.
💡
External cooling is the only way to get the Redmi 9 to keep a stable FPS in long game sessions, as there is not enough passive radiator inside.
