The question of which Snapdragon is installed in the popular budget smartphone Xiaomi Redmi 9, worries many potential buyers who choose the device for everyday tasks. This device has become one of the bestsellers in its price segment due to the excellent balance between cost and functionality. Understanding the characteristics of the processor allows you to determine exactly whether the gadget will cope with the demanding applications that you plan to use.
Xiaomi has equipped this model with a Qualcomm Snapdragon 665 chipset that was released back in 2019. Although it is not the latest solution, it has proven to be a reliable workhorse for the middle class. The architecture of this processor provides stable interface, fast application loading and moderate power consumption, which is critical for autonomy.
In this review, we’ll take a closer look at the technical specifications of the Snapdragon 665, compare it to competitors, and see what the chip can do in 2026-2026, see the real performance benchmarks and see if you can expect lags in modern games, which will help you make an informed decision when buying or upgrading your mobile device.
Specifications of Qualcomm Snapdragon 665
At the heart of the Xiaomi Redmi 9 is the 11-nanometer Snapdragon 665, an 11-nanometer processor chipset that represents an evolution of the popular 660, but with improved energy efficiency and AI support, with eight cores divided into two clusters to efficiently distribute the load.
The first cluster, known as Gold, consists of four Cortex-A73 performance cores with clock speeds up to 2.0 GHz. These are the ones that get in the works when you run heavy apps or games that require maximum power. The second cluster, Silver, includes four energy-efficient 1.8 GHz Cortex-A53 cores that take on background tasks and standby, saving battery power.
⚠️ Note: Don’t confuse the global version of Redmi 9 with the Chinese version, as modifications with other processors may have been encountered in some regions, although the standard for international sales is the Snapdragon 665 bundle and the Snapdragon 665 bundle. GPU Adreno 610.
Graphics processing is taken over by the Adreno 610 accelerator, which supports modern API, including Vulkan and OpenGL ES This allows you to run most mobile games, albeit with certain schedule restrictions. X12 LTE, providing download speeds up to 600 Mbps, which is enough for comfortable surfing and streaming video.
An important feature is the built-in third-generation AI Engine unit, which speeds up camera performance and facial recognition. The processor supports up to 8 GB of LPDDR4X RAM, which provides fast multitasking. Below is a table with the main technical parameters for clarity:
| Parameter | Meaning |
|---|---|
| Technique | 11nm |
| CPUs (clusters) | 4x Cortex-A73 (2.0 GHz) + 4x Cortex-A53 (1.8 GHz) |
| GPU | Adreno 610 |
| Memory. | LPDDR4X to 8GB |

Performance in benchmarks and synthetic tests
To objectively assess what Snapdragon is worth in the Xiaomi Redmi 9, you need to look at the numbers. In the popular AnTuTu test (versions 8 and 9), the device scores in the region of 170,000 – 185,000 points. This is a typical result for the budget segment, which allows the smartphone to be above many ultra-budget competitors, but lag behind the gaming models of the middle class.
In the Geekbench test 5, which measures the performance of the processor, Redmi 9 roughly 290-310 scoring in single-threaded mode and about 1250-1300 These numbers indicate that there is more than enough power for everyday tasks. MIUI It works smoothly, swipes and transitions between menus do not cause delays.
But you have to consider heat generation over long periods of time, and if you're playing long-term games or recording high-resolution video, the processor can get hot, which leads to trotting, which is a forced frequency reduction to protect components, which is normal for an 11nm process, but it limits the duration of the gaming sessions at maximum settings.
💡
To reduce the heat during games, remove the protective case and reduce the brightness of the screen – this will help the processor to keep the maximum frequencies longer.
Storage speed also depends on the type of memory, but the memory controller in the Snapdragon 665 is fast enough for eMMC 5.1 and UFS 2.1. Apps are launched in an acceptable time, although heavy programs like Photoshop or video editors can open with a noticeable pause.
Redmi 9 Game Features: What to Play
The issue of gaming potential is often crucial when choosing a smartphone. Adreno 610 graphics accelerator in conjunction with the Snapdragon 665 allows you to run almost all popular projects from Google Play, but with reservations on the quality of graphics. Let's analyze the performance in specific hits of mobile indria.
In PUBG Mobile and Call of Duty: Mobile, the smartphone is able to deliver stable 30-40 frames per second on low and medium graphics settings. High settings are not recommended, since framerate will become unstable, and control will become jittery, which is critical in shooters. For a comfortable game, it is better to sacrifice texture detail in favor of smoothness.
- 🎮 Mobile Legends: Bang Bang – works great on high settings, stable 60 FPS.
- 🏎️ Asphalt 9: Legends – Playable on mid-settings, rare micro-freezes possible.
- 👑 Clash Royale / Brawl Stars – maximum graphics, no performance issues.
- ⚔️ Genshin Impact – playable only at minimum settings and resolution, strong heating.
⚠️ Warning: Genshin Impact is extremely demanding and can cause strong heating of the Redmi 9 body, which reduces battery life with prolonged use.
For retro console emulators (PSP, Nintendo DS, Sega), the power of the Snapdragon 665 is enough. You can comfortably navigate the projects of the PlayStation 1 era and even some games with PSP in full resolution. This makes the Xiaomi Redmi 9 a great portable retro console for fans of classics.
Why do games slow down after the update?
Energy efficiency and impact on autonomy
One of the main advantages of using the Snapdragon 665 processor in Xiaomi Redmi 9 is its energy efficiency. In combination with a huge battery capacity of 5020 mAh, the smartphone is able to withstand up to two days of active use. 11-nanometer process technology allows you to minimize energy loss when converting electricity into computing operations.
With 4G on and active messenger, the device loses less than 5-7% of its charge per day. When you use screen time (social media, YouTube, browser), you can reach 7-8 hours, which is an outstanding result for the budget class, due to the fact that the Cortex-A53 cores take over most of the background processes.
However, it is important to remember that when starting a heavy 3D-applications come into operation kernels Cortex-A73, The energy consumption increases dramatically, and in these scenarios, the charge can go away at a rate of speed. 15-20% Fast-charging technology. 18 Wh (although the package often comes with a block on the 10 Wh-wh 22.5 W, depending on the region and configuration, allows you to fully restore the capacity in about 2-2.5 hour.
