Qualcomm Snapdragon 636: A Budget Processor Still Relevant in 2025?
(Analysis for users seeking a balance between price and performance)
Introduction
In 2025, mobile processors continue to evolve, but even outdated chips find their niche. The Qualcomm Snapdragon 636, released in 2017, is still used in budget smartphones. Why? This article will analyze its strengths and weaknesses, relevance in 2025, and help you understand who it is suitable for.
Architecture and Manufacturing Process: Why is 14 nm Still Viable?
Cores and Frequencies:
The Snapdragon 636 features an 8-core Kryo 260 architecture (described as "semi-custom"), divided into two clusters:
- 4 high-performance cores Cortex-A73 with a frequency of up to 1.8 GHz;
- 4 energy-efficient cores Cortex-A53 with a frequency of up to 1.6 GHz.
This approach (big.LITTLE) optimizes energy consumption: heavy tasks are handled by the powerful cores, while background processes are managed by the economical ones.
Graphics:
The Adreno 509 GPU supports Vulkan 1.0 and OpenGL ES 3.2 APIs. While this is insufficient for modern games in 2025, it suffices for basic graphics and Full HD displays.
Manufacturing Process:
14 nm is an outdated standard (compared to the 4-5 nm used in flagship devices of 2025). This means higher heat generation and less efficient energy consumption. However, for less demanding tasks, the technology remains functional, especially in conjunction with a TDP of 5 watts.
Real-World Performance: What Can It Do in 2025?
Gaming:
- Casual Gaming: Games like Candy Crush, Among Us, and Clash Royale run smoothly.
- Moderate Load: PUBG Mobile or Genshin Impact can run on low settings with FPS around 25-30, but drops may occur.
- Heat Management: Due to the 14 nm process, the processor heats up under prolonged load, but the 5W TDP helps alleviate the problem.
Multimedia:
- Video: Streaming Full HD (Netflix, YouTube) is smooth. 4K videos may stutter.
- Audio: Support for aptX and AAC codecs improves sound quality in wireless headphones.
AI Applications:
The Snapdragon 636 lacks a dedicated Neural Processing Unit (NPU). Basic AI functions (like background blur in Zoom) operate through the CPU/GPU, but are slower than on modern chips.
Energy Consumption:
A 4000 mAh battery provides 6-8 hours of screen time in mixed usage. An 18W charger (QC 3.0) can fully charge the battery in 1.5-2 hours.
Built-in Modules: LTE, Wi-Fi, and Satellites
- Modem: The Snapdragon X12 LTE (up to 600 Mbps download) is outdated for 2025, but sufficient for basic tasks. 5G is absent.
- Wi-Fi: Only Wi-Fi 5 (802.11ac) with no support for Wi-Fi 6/6E. Maximum speed is 433 Mbps.
- Bluetooth: Version 5.0 with LE support—compatible with most devices.
- Navigation: GPS, GLONASS, BeiDou with accuracy up to 3 meters.
Comparison with Competitors: Who is Stronger?
Generation vs. Generation:
- Snapdragon 660: About 20% faster in CPU performance, with Adreno 512 being 30% more powerful.
- MediaTek Helio P60: Comparable performance but worse game optimization.
- Snapdragon 480 (2021): 8nm, 5G, higher performance in Geekbench 6 (SC: 530, MC: 1600).
In 2025:
- Unisoc Tiger T610: Cheaper but with weaker graphics.
- Snapdragon 4 Gen 2: A better choice for $200: 6nm, 5G, AnTuTu score of 350K.
Conclusion: The Snapdragon 636 falls short against modern budget chips but is cheaper to produce.
Use Cases: Who Is It For?
1. Daily Tasks:
- Social networks, messengers, and browsing—ideal performance.
- Multitasking works, but with limitations (e.g., 3-4 apps in the background).
2. Gaming:
- Only for casual games. Lower resolution will be necessary for PUBG or CoD Mobile.
3. Photo and Video:
- Camera support for up to 24 MP (single) or 16 MP (dual).
- Video recording: 4K@30fps with potential overheating issues.
- Night photography: basic algorithms without AI enhancements.
Pros and Cons: Is It Worth Buying in 2025?
Pros:
- Price: Smartphones with the SD636 cost around $150-200.
- Energy Efficiency: Good battery life.
- Sufficient power for basic tasks.
Cons:
- Outdated manufacturing process: Heating issues and low performance.
- No 5G or Wi-Fi 6.
- Weaker GPU: Not suitable for gamers.
Practical Tips: How to Choose a Smartphone with SD636?
1. RAM: A minimum of 4 GB (preferably 6 GB for multitasking).
2. Storage: Choose models with UFS 2.1 (not eMMC) for faster app loading.
3. Cooling: Look for smartphones with copper pipes or graphite coatings.
4. Battery: At least 4000 mAh for comfortable use.
5. Updates: Android 13/14 is the limit. Check whether the manufacturer promises security patches.
Examples of 2025 Devices:
- Xiaomi Redmi Note 12 Lite: $169, 6 GB/128 GB, AMOLED display.
- Realme C55 Pro: $199, 90 Hz display, 5000 mAh.
Final Conclusion: Who is the Snapdragon 636 Suitable For?
This processor is a choice for:
- Budget users: Those who prioritize price over performance.
- Backup devices: Such as for travel or as a "work" phone.
- Older adults: Simple tasks with long battery life.
Main Benefits:
- Affordability.
- Proven reliability.
- Sufficient functionality for basic needs.
Conclusion:
The Qualcomm Snapdragon 636 in 2025 is not the most powerful but one of the most affordable options. If you are not a gamer and do not plan to use your smartphone for demanding tasks, it remains a reasonable compromise. However, for $200-250, you can find devices with 5G and modern chips—consider the future!
