Specifications of the Snapdragon 660 in the Redmi Note 7
Qualcomm Snapdragon 660 processor (codename) SDM660) It was announced in May 2017, but it still remains relevant for the budget segment. It is built on a 14-nm process technology (FinFET). LPP Samsung, which provides a balance between performance and power consumption.
The chipset architecture includes:
- 🖥️ 8 Kryo 260 cores (4 high-performance) Cortex-A73 @ 2.2 GHz + 4 energy efficient Cortex-A53 @ 1.8 GHz)
- 🎨 Adreno 512 Graphics Accelerator with Vulkan 1.0 and OpenGL Support ES 3.2
- 📶 modem X12 LTE (Cat. 12/13, speed 600 Mbit/s)
- 📷 Support for cameras up to 24 MP (or dual 16 MP) with Qualcomm Spectra 160 technology ISP
Important detail: in the Redmi Note 7 uses a modification of the Snapdragon 660 with an artificially low frequency GPU It's up to 700 MHz (instead of 850 MHz in the reference version), which is designed to reduce heat, but it cuts down on game performance a little bit.
| Parameter | Snapdragon 660 (Redmi Note 7) | Snapdragon 675 (Redmi Note 7 Pro) |
|---|---|---|
| Technique | 14nm | 11nm |
| CPU (max frequency) | 2.2 GHz (A73) | 2.0 GHz (A76) |
| GP (frequency) | 700 MHz (Adreno 512) | 845 MHz (Adreno 612) |
| AnTuTu (Grade Average) | ~140 000 | ~180 000 |
⚠️ Note: In some regions (for example, India) Redmi Note was sold 7S with a Snapdragon 660 processor, but with a 48MP camera. This does not affect performance, but can cause confusion when buying a used device.
2. Benchmarks and real performance
In synthetic tests, the Snapdragon 660 shows the following results (data from 2026 for the Redmi Note 7 with the following data). MIUI 14):
- 📈 AnTuTu 9: 135,000–145,000 points (depending on firmware)
- 🧠 Geekbench 5 (Single-Core): 310-330 points
- 🧠 Geekbench 5 (Multi-Core): 1,300–1,400 points
- 🎮 3DMark Sling Shot: ~2,200 points (volcano)
For comparison: the flagship Snapdragon 845 (2018) is gaining momentum ~280,000 in AnTuTu, and budget Helio G85 (2020) — ~200,000, I mean. SD660 It is in the middle, which makes it optimal for everyday tasks.
Real use cases:
- 📱 Social networks and instant messengers: No lags even when working at the same time 10+ background
- 📷 Photo and video: Processing RAW-snapshot ~3-5 seconds, rendering 4K-Video is possible, but with a slowdown
- 🎵 Multimedia: Playing video before 4K@30fps No problem, but HDR may be
💡
To get the maximum performance in benchmarks, restart your phone before the test and close all background apps through Settings. → Annexes → All applications.
3. Gaming Opportunities: What will pull the Snapdragon 660?
The Adreno 512 graphics accelerator paired with an understated frequency (700 MHz) imposes restrictions on modern games, but for most projects in 2020-2022, the Redmi Note 7 remains a playable device.
| Game. | Settings | FPS (medium) | Overheating |
|---|---|---|---|
| PUBG Mobile | HD + Ultra | 25–30 | Medium (up to 45)°C) |
| Call of Duty: Mobile | Average. | 40–45 | Low. |
| Genshin Impact | Low. + 30 FPS | 25-30 (drops to 20) | High (up to 50)°C) |
| Free Fire | Ultra | 40+ (stably) | Absent. |
Key observations:
- 🔥 Open world games (Genshin Impact, Honkai: Star Rail) work only at minimal settings and heat the processor to critical values.
- ⚡ Light shooters (Free Fire, Mobile Legends) go on maximum settings without friezes.
- 🔄 After 30-40 minutes of intense play, trottling (automatic frequency reduction) begins, which leads to a fall. FPS 10-15%.
⚠️ Warning: If artifacts (blurred textures, flickering) appear in the game, this may indicate problems with thermopaste or overheating. CPU Monitor.
Enable performance mode in Settings → Special opportunities → Game mode
Set a limit FPS 30 or 45 (in the game settings)

Energy efficiency and autonomy
With its 14nm process technology and optimized architecture, the Snapdragon 660 demonstrates good energy efficiency. 1080p 50% brightness of the device shows the following results:
- 📞 Talking about 4G: ~1% battery per hour
- 🌐 Surfing the Internet (Wi-Fi): ~5-7% per hour
- 🎮 Games (PUBG, mid-set): ~15-18% per hour
- 📷 Video recording 1080p: ~12-15% per hour
With a battery of 4000 mAh Redmi Note 7 on average holds:
- 🔋 Screen time: 6-8 hours (at mixed load)
- ⏳ Standby: 2-3 days (with switched off) 4G)
Why does the battery run out quickly in the cold?
Tips for extending autonomy:
- Turn off Constant Network Search in Settings → SIM-maps and mobile networks.
- Use dark themes of design (AMOLED-There are no screens in the Note 7, but dark pixels are on the screen. LCD They save a lot of charge, too).
- Limit the background activity of applications through Settings → Battery → Optimizing the battery.
5.Typical Processor Problems and Their Solutions
Despite the reliability of the Snapdragon 660, owners of the Redmi Note 7 sometimes face the following problems:
🔥 Overheating and trottling
Symptoms: Phone heats up above 50°C, performance drops sharply, games begin to slow down".
Causes and solutions:
- 🧹 Charging connector contamination: Blow the port with compressed air or clean gently with a toothpick.
- 🔧 Thermopaste wear: If the phone is older than 3 years, a replacement of the thermal interface (repair cost) may be required. ~1 500 ₽).
- 📱 Background Processes: Install Greenify to Forced Hibernation of Unneeded Apps.
⚡ Self-involved reboots
Symptoms: The phone suddenly turns off and on, especially when it is under high load.
Reasons:
- 🔋 Failure of the battery (blown, loss of capacity)
- 🛠️ Poor contact between the processor and the motherboard (required soldering)
- 🤖 Firmware failure (will help flashing through Fastboot)
⚠️ Note: If the reboots are accompanied by a blue screen with an error (e.g. hardware revision check fail), this indicates a hardware failure of the motherboard. ₽.
🐢 Slowing down over time
Decisions:
- Reset the cache through Settings → Memory. → Clearing the cache.
- Disable the system animation (enable Developer Mode and install Animation) = 0.5x).
- Install a custom core (e.g., FrancoKernel) to optimize the processor frequencies.
💡
If the phone is slowing down after the update MIUI, Try to roll back to the previous firmware version through Recovery. Often new builds contain bugs that slow down the processor.
6.Comparison to competitors: Should you buy the Redmi Note 7 in 2026?
As of 2026, the Snapdragon 660 is inferior to today’s low-end chipsets, but still competitive for everyday tasks.

When is the best time to consider alternatives:
- 🎮 You play modern games (Genshin Impact, Diablo Immortal).
- 🚀 You need it. 5G Or a faster modem for mobile internet.
- ⏳ You plan to use your phone for more than 2 years (SD660 obsolete).
7.How to speed up the processor without risking the phone
If your Redmi Note 7 is slower than before, you can try the following safe overclocking and optimization methods:
🛠️ Programmatic methods
- 📱 Shutdown MIUI-Optimizations: Go to Settings → About the phone, press 7 times on the version MIUI, Then in Developer Settings turn off Optimization MIUI and window animation.
- 🔧 Use of the GPU-Rendering: In the same developer settings, enable Forced Use GPU (Improves the smoothness of the interface).
- 🗑️ Cleaning Dalvik Cache: Through Recovery (Squeeze Power) + Volume up when turned on) select Wipe → Advanced Wipe → Dalvik Cache.
⚙️ Hardware methods (for experienced users)
- 🔥 Replace thermopaste: If the phone overheats, a new thermopaste (e.g. Arctic) MX-4) can reduce the temperature by 5-10°C.
- 🔋 Battery replacement: A worn-out battery makes the processor run in power saving mode, which reduces performance.
⚠️ Note: Do not use CPU overclocking applications (such as SetCPU or Kernel Adiutor) without root permissions. Incorrect settings can overheat and cause the chipset to fail. If you are not sure, it is better to limit yourself to software optimization.
