Unisoc SC9863A
Unisoc SC9863A: A Budget Processor for Basic Tasks in 2025
Overview of Architecture, Performance, and Use Cases
Introduction
In the world of mobile technology in 2025, dominated by 5G, AI accelerators, and processors on a 5nm process node, the Unisoc SC9863A remains a niche solution. Released back in 2018, this chip is still found in ultra-budget smartphones priced at $100–150. But who is it suitable for in an era of technological abundance? Let’s delve into the details.
1. Architecture and Process Technology: Conservative Approach
Cores and Frequencies
The SC9863A is built on a classic heterogeneous architecture featuring 8 cores:
- 4 Cortex-A55 cores clocked at 1.6 GHz for resource-intensive tasks.
- 4 Cortex-A55 cores clocked at 1.2 GHz for background processes.
Despite having the same cores, the cluster arrangement allows for optimized power consumption. However, the use of only Cortex-A55 (rather than the newer A75/A76) limits performance in single-threaded tasks.
GPU: PowerVR GE8322
The PowerVR GE8322 graphics processor, operating at up to 550 MHz, is the chip's weak point. It supports resolutions up to HD+ (1600×720) and handles simple animations, but is poorly suited for 3D games.
28nm Process Technology
The 28nm technology in 2025 seems outdated. In comparison, competitors (e.g., MediaTek Helio G37) utilize 12nm, offering better performance and energy efficiency ratios.
2. Performance: Realistic Expectations
Gaming
- Geekbench 6 Single-Core: 165 — lower than Snapdragon 439 (190).
- AnTuTu 10: 160,099 — two times less than the budget Snapdragon 680.
The SC9863A can only run light games like Candy Crush or Subway Surfers at low settings. PUBG Mobile or Genshin Impact are out of reach.
Multimedia
- Video support: 1080p at 30fps (encoding/decoding).
- Displays: Maximum of HD+ (due to GPU limitations).
The chip is suitable for YouTube, social media, and video calls but cannot handle 4K content.
AI Applications
The lack of an NPU (neural processor unit) makes it impossible to use complex AI filters in the camera or offline voice assistants.
Power Consumption and Heat Generation
- TDP 3W — a modest figure, but due to the 28nm process, the chip heats up under prolonged load.
- In smartphones with a 4000–5000 mAh battery, it provides 1–1.5 days of moderate use.
3. Integrated Modules: No Frills
- Modem: 4G LTE Cat.7 (up to 300 Mbps). 5G is not supported.
- Wi-Fi: Only 802.11n (2.4 GHz) — slower and less stable than Wi-Fi 5.
- Bluetooth: Version 4.2 without LE Audio support.
- Navigation: GPS, GLONASS, BeiDou — sufficient for basic tasks.
These modules are suitable for rural areas or as backup devices, but in urban environments with dense 5G and Wi-Fi 6 coverage, a smartphone with the SC9863A will lag behind.
4. Comparison with Competitors
Direct Competitors in 2025:
- MediaTek Helio A22 (12nm, 4×A53): Cheaper ($50–70) but weaker in multithreading.
- Qualcomm Snapdragon 429 (12nm, 4×A53): Better optimization for Android, but only 4 cores.
Previous Generations of Unisoc:
- Tiger T310 (12nm, 1×A75 + 3×A55): 30% more powerful in single-threaded tasks.
Conclusion: SC9863A is a compromise for devices priced below $100, where the number of cores matters more than their quality.
5. Use Cases
Gaming
Only for casual games. Even Mobile Legends at medium settings will lag.
Everyday Tasks
- Messengers, Social Media: Smooth operation.
- Multitasking: Opening 3–4 apps simultaneously will cause sluggishness.
Photo and Video
- Maximum camera resolution: 13 MP (interpolated to 21 MP).
- Video recording: 1080p at 30fps without stabilization.
Photos in good lighting are acceptable, but nighttime shots are noisy and blurred.
6. Pros and Cons
Pros:
- Low device cost ($80–150).
- LTE support for basic internet usage.
- Sufficient cores for light multitasking.
Cons:
- Outdated 28nm process technology.
- Weak GPU and lack of 5G.
- Limited support for modern communication standards.
7. Smartphone Selection Tips
- Price: Don’t overpay. If the device costs more than $120, look for alternatives (e.g., Realme C55 with Snapdragon 680).
- Battery: Choose models with at least 4000 mAh — the chip is inefficient during heavy use.
- Screen: HD+ with IPS matrix is optimal.
- Storage: Minimum of 64 GB — you won’t handle flagship games, but there’s enough space for photos and videos.
Typical 2025 Devices with SC9863A:
- Teclast P30HD: Tablet priced at $90 with a 10-inch screen.
- Blackview A20: Smartphone with a 5000 mAh battery priced at $80.
8. Final Verdict: Who is this processor for?
The Unisoc SC9863A is suitable for:
1. Budget users: Those who need a device for calls, WhatsApp, and YouTube.
2. Backup devices: As a second smartphone for travel or work.
3. Elderly people: Simple interface and lack of complex features.
Main Benefits:
- Minimal price.
- Sufficient performance for basic needs.
- Compatibility with the latest versions of Android Go.
Conclusion
The Unisoc SC9863A in 2025 is not a contender for “Processor of the Year,” but it plays an important role in the ultra-budget device market. If your needs are modest and your budget is limited, a smartphone powered by this chip will serve you reliably. However, for gaming, photography, or working with AI, look for more modern solutions.
