The Xiaomi Redmi Note 7, released in January 2019, has become one of the most popular budget smartphones of its time. Even 5 years later, the device continues to be in demand in the secondary market - and largely thanks to its "heart": Qualcomm Snapdragon 660 processor. This chipset was a real breakthrough for the mid-range segment, offering flagship performance at a third of the price.
But why the Snapdragon 660? What is it and how it will perform in 2026? In this article, we will examine the architecture of the processor, its specifications, compare it with modern budget chips and answer the question: is it worth buying the Redmi Note 7 today because of this processor, and learn how to test the model of the chipset on your device and what pitfalls can be expected by owners when updating firmware or overclocking.
Specifications of the Snapdragon 660 in the Redmi Note 7
Qualcomm Snapdragon 660 processor (codename) SDM660) It was announced in May 2017, but it peaked in 2018-2019, the first mid-range chipset built on a 14nm process (as opposed to its predecessors’ 28nm), which significantly reduced power consumption and heat generation. Redmi Note 7 uses a modification MSM8976 Plus – optimized version for smartphones Xiaomi.
The main parameters of the chipset:
- 🔹 Central processing unit (CPU): 8 Kryo cores 260 (4 × 2.2 GHz + 4 × 1.8 GHz, architecture ARM Cortex-A73/A53
- 🎮 Graphics processor (GPU): Adreno 512 with frequency up to 850 MHz

- 📸 ISP (Image processing: Spectra 160 (up to 24 MP or dual 16 MP cameras)
An important nuance: in some regions (for example, India) sold Redmi Note 7 with a Snapdragon 636 processor - this is a different model! To avoid confusion, check the markings on the box or in the settings of the smartphone (for more details in the section "How to find out the model of the processor").
Architecture and Performance: Why the Snapdragon 660 was revolutionary
The main advantage of Snapdragon 660 competitors (e.g., Helio) P60 from MediaTek) is the use of Kryo cores 260, Qualcomm developed on the basis of architecture ARM Cortex-A73/A53. Unlike standard cores, Kryo is optimized for specific tasks:
- 🔥 4 "big" cores (Cortex-A73) 2.2 GHz is responsible for heavy tasks: games, video rendering, multitasking.
- ⚡ 4 "small" cores (Cortex-A53) 1.8 GHz saves battery power for simple operations (social networks, calls).
This configuration is called big.LITTLE and allows you to balance between performance and energy efficiency. For comparison, the Snapdragon 636 (which was also installed in the Redmi Note 7) uses Kryo 260 cores, but at a lower frequency (1.8 GHz for large cores), which affects the speed of operation.
The Adreno 512 graphics accelerator is 30% more powerful than its predecessor (Adreno 509 in the Snapdragon 630) and supports:
- 🎮 Vulkan 1.0 and OpenGL ES 3.2 - Modern graphics API play-off.
- 🖼️ HDR-rendering and processing images in resolution before 4K.
- 🕹️ Quick Charge 4.0 – Fast charging (although the Redmi Note 7 uses Quick Charge 3.0).
💡
If your Redmi Note 7 is slowing down in games, try turning off the smoothing in the graphics settings (for example, in the video game). PUBG Mobile Select Balanced Mode Instead HDR). This will reduce the load on the Adreno 512 and increase the load on the Adreno. FPS.
