What processor is installed in the Xiaomi Redmi Note 8T: a detailed analysis of the Snapdragon 665

Many users are still wondering what processor is installed in the Xiaomi Redmi Note 8T, and it is no coincidence that this model, released in late 2019, became one of the most popular in the budget segment due to the successful combination of price and quality.

Unlike its Redmi Note 8 sibling, the T version received this processor, not the Helio G85, which often causes confusion among customers. Understanding the chip architecture allows you to better assess the real capabilities of the smartphone in gaming, camera work and multitasking. In this article, we will examine in detail the technical features of the platform, its impact on autonomy and compare with modern analogues.

It's important to know that the Redmi Note 8T is based on an 11nm process, which provides a balance between power consumption and heating, and it's a key factor that has allowed the device to remain relevant in the market for more than two years after its launch. Let's go into the specs and see what this system is capable of in 2026.

Architecture and technical characteristics of the chipset

The core of the smartphone’s performance is the Snapdragon 665, built on the ARMv8 architecture. This chipset is an eight-core system where the cores are divided into two clusters to optimize energy consumption. The four Cortex-A73 performance cores run at frequencies up to 2.0 GHz, providing performance in heavy applications. The remaining four Cortex-A53 cores operate at 1.8 GHz and are responsible for background processes and simple tasks.

The graphics processing is handled by the Adreno 610 integrated accelerator.This GPU supports modern graphics APIs, including Vulkan and OpenGL ES 3.2, which is important for running current mobile games. While it is not a flagship solution, the bundle of cores and graphics allows the MIUI interface to run smoothly in most use cases.

The 11nm process was a significant step forward compared to the Snapdragon 600 series predecessors, which were produced at 14nm standards. The reduction in the standards allowed to reduce heat generation while maintaining a high clock frequency, this is especially noticeable with prolonged use of navigation or watching high-resolution video.

Performance in benchmarks and real-world tasks

When evaluating which processor Xiaomi Redmi Note 8T, you can not ignore the dry numbers of tests. In the popular benchmark AnTuTu (version 8), the smartphone consistently scores about 170,000 – 180,000 points, an average result for the budget segment of the period, which allows you to comfortably use social networks, messengers and streaming services.

In the Geekbench test, the situation is as follows: in single-threaded mode, the device dials approximately 300-320 and in the multi-threaded, about 1300-1400 These are indicators that tell us that for heavy computation, such as video rendering or processing. RAW-But for everyday use, the power reserve is enough.

It supports RAM type LPDDR4X with a frequency of up to 1866 MHz. In conjunction with the eMMC 5.1 drive (less often UFS 2.1 depending on the region and version), the download speed of applications remains acceptable. Heavy games can load longer than on flagships, but the stability of the system does not suffer.

Gaming capabilities and graphics processor

The Adreno 610 graphics chip is one of the most common in the budget segment, and it is capable of running popular online shooters such as PUBG Mobile and Call of Duty: Mobile. However, users need to understand the limitations: maximum graphics settings are not available here, and the game will go on low or medium settings at a frequency of about 30-40 frames per second.

For less demanding projects like Clash of Clans, Brawl Stars or casual puzzles, the CPU power is abundant. Here you get stable 60 FPS and smooth animation without jerks. The heat generation in such games is minimal, the smartphone body heats up slightly, allowing you to play for hours without trottling.

If you plan to use a device to emulate console games (e.g., via PPSSPP or PSP emulators), the Snapdragon 665 will do well. Many projects work in full screen size with improved texture. However, emulating more modern platforms like the PlayStation 1 or Nintendo 64 may require lower resolution to achieve playable frame rates.

• 🎮 PUBG Mobile: Works on low settings, around 30 FPS, Possible drawdowns in heavy scenes.
• 🏎️ Asphalt 9: Launches on medium settings, requires a stable Internet connection to download resources.
• ⚔️ Genshin Impact: Launches at minimum settings, but playability is low (20-25 FPS), heat-up.
• 🃏 Hearthstone / Chess: Perfect for maximum settings without heating.

⚠️ Attention: For long gaming sessions at high loads, the system can artificially reduce the brightness of the screen for cooling.

The impact of the processor on the work of the camera and multimedia

One of the strengths of the Snapdragon 665 is the built-in ISP (Image Signal Processor), which is responsible for processing the signal from the camera matrix. The Redmi Note 8T has a 48 MP core module, and the processor successfully copes with pixel combining (Pixel Binning technology), creating final images of 12 MP in high detail and low noise.

Video shooting is also completely dependent on the capabilities of the chipset. The processor allows you to write video in 4K resolution at 30 frames per second or 1080p at 60 frames per second. Image stabilization in the Redmi Note 8T is electronic (EIS) and implemented by the software methods of the processor, which sometimes leads to a slight crop of the frame when shaking actively.

Multimedia capabilities are being expanded with codec support. The chipset hardware decodes H.264, H.265 (HEVC), VP9 video formats. This means that when you watch movies in high resolution through streaming services, the load on the system is minimal and the battery is spent economically. The sound processor also supports Dolby Audio technologies, improving the quality of playback through headphones.

For maximum low-light photo quality, use manual or night mode, as the processor algorithms require 2-3 seconds to process multiple frames.

Energy efficiency and heat generation

Power consumption is a big issue for any mobile device. With 11nm process technology, the Snapdragon 665 demonstrates excellent performance. In standby or text reading, the smartphone can last up to two days without recharging. Active use (web surfing, video) allows you to expect 6-7 hours of screen time.

The heat sink in the Redmi Note 8T is designed with graphite gaskets and a copper tube (in some revisions), because the processor is not heavy-duty, it rarely reaches critical temperatures under normal conditions, and only overheats when charging and running heavy games simultaneously, which is typical for most smartphones in this class.

Comparative analysis shows that this chipset is colder than some of MediaTek’s competitors of the same period, which often suffer from extreme temperature spikes under load.

Comparison with competitors and relevance in 2026

At the time of release, MediaTek’s main competitor was the Helio G85, which was installed in the regular Redmi Note 8. Although the Helio G85 has newer Cortex-A75 cores, in real-world scenarios, the Snapdragon 665 was often more stable and better optimized for cameras. The difference in performance is about 10-15% in favor of MediaTek, but the difference in energy efficiency may be in favor of Qualcomm.

By 2026, this processor is already considered obsolete for demanding users; modern applications are getting heavier, and 4-6 GB of RAM in conjunction with this CPU can run slower than you would like, but for the secondary market, a phone for a child, an elderly person or as a second device for work, this is still a great option.

If you choose between the Redmi Note 8T and the new budget for the same price, it is worth considering that new models (for example, on the Snapdragon 680 or Helio G88) will offer only a slight increase in power, but will get a more recent version of Android out of the box and support for security updates.

⚠️ Note: When buying a used device, pay attention to the state of the battery. Snapdragon 665 processor is efficient, but the worn-out battery will negate all its benefits.
