Samsung Exynos 7884B: Budget Processor for Everyday Tasks in 2025
April 2025
Introduction
In the world of mobile technology, where flagship processors continually amaze with innovations, budget chips remain indispensable for millions of users. The Samsung Exynos 7884B is one such workhorse that continues to power low-cost smartphones even in 2025. Let’s explore who this SoC is suitable for, what it is capable of, and how it compares to competitors.
1. Architecture and Process Technology: Modest Ambitions
Cores and Frequencies
The Exynos 7884B is built on an octa-core architecture with two clusters:
- 4 Cortex-A73 cores with a frequency of up to 1.56 GHz for resource-intensive tasks.
- 4 Cortex-A53 cores with a frequency of up to 1.35 GHz for background processes.
This configuration (big.LITTLE) provides a balance between performance and energy efficiency. However, its clock speeds are lower than contemporary counterparts, and the 14 nm process technology (compared to 6–8 nm in competitors of 2025) increases energy consumption and heat generation.
Graphics Mali-G71 MP2
The Mali-G71 MP2 GPU is an outdated solution even at the time of the chip's release. The two compute units handle only simple graphics:
- Support for resolutions up to Full HD+ (1080 × 2520 pixels).
- Lack of technologies like Vulkan 1.1 — only OpenGL ES 3.2 is available.
Energy Consumption
The chip has a TDP of 5 W, which is acceptable for 14 nm technology, but overheating may occur under load. In everyday scenarios (social media, video), the chip remains cool.
2. Performance in Real Tasks: Modest but Stable
Gaming
The Exynos 7884B is suitable for less demanding games:
- Mobile Legends, Among Us, Subway Surfers — stable 60 FPS on medium settings.
- Genshin Impact, Call of Duty: Mobile — only low settings and 25–30 FPS with drops.
Multimedia
The chip decodes video in 1080p 60 FPS (H.264, H.265), but 4K content results in stuttering. Streaming video playback (YouTube, Netflix) in Full HD is problem-free.
AI Applications
The absence of an NPU or DSP for AI operations limits capabilities:
- Filters in Instagram and FaceApp work slower than on modern chips.
- Face recognition on the camera is basic, without complex scenarios.
Energy Consumption
A 4000 mAh battery will provide 6–8 hours of screen time in mixed usage. With active use (gaming, navigation), the smartphone will require charging after 3–4 hours.
3. Built-in Modules: Only the Basics
Modem
- 4G LTE Cat. 12 with a maximum speed of up to 600 Mbps (download) and 150 Mbps (upload).
- 5G is missing — this is a significant drawback in 2025 for markets with advanced infrastructure.
Wi-Fi and Bluetooth
- Wi-Fi 5 (802.11ac) supporting dual-band connectivity (2.4/5 GHz).
- Bluetooth 5.0 — compatible with most devices but lacks advanced features like LE Audio.
Navigation
Support for GPS, GLONASS, Galileo — adequate precision for maps and taxis. Satellite emergency communication systems (like in the iPhone 14+) are not included.
4. Comparison with Competitors: Market Position
Exynos 7884B vs. Qualcomm Snapdragon 680
- The Snapdragon 680 (6 nm) excels in energy efficiency, supporting cameras up to 108 MP and 90 Hz displays.
- In AnTuTu 10 tests, the Snapdragon scores around 220,000 points compared to 190,404 for the Exynos.
Exynos 7884B vs. MediaTek Helio G85
- The Helio G85 (12 nm) offers a more powerful Mali-G52 MC2 GPU, providing +20% FPS in games.
Conclusion: In 2025, the Exynos 7884B is the choice for ultra-budget devices (up to $150), while competitors dominate the $150–250 segment.
5. Use Cases: Comfortable Limits
Gaming
Only suitable for casual games. PUBG Mobile or Fortnite will require lowering the resolution and graphics.
Everyday Tasks
- Social media, messengers, web surfing — smooth performance.
- Multitasking mode — limited to 2–3 applications.
Photo and Video
- Maximum camera resolution — 21 MP (single camera) or 16+5 MP (dual).
- Video recording — 1080p 30 FPS. Electronic stabilization introduces artifacts.
6. Pros and Cons
Pros:
- Low device cost (from $120).
- Stable performance in basic scenarios.
- Support for modern Android versions (up to 2024).
Cons:
- Weak GPU and lack of 5G.
- Heating under prolonged load.
- Limited capabilities for AI and shooting.
7. Practical Tips: How to Choose a Smartphone with Exynos 7884B
1. RAM Volume: At least 4 GB — for comfortable operation in 2025.
2. Screen: IPS matrix with a 60 Hz refresh rate — AMOLED is rare in this segment.
3. Battery: From 4000 mAh — compensates for the chip's suboptimal energy efficiency.
4. Cameras: Do not expect miracles — even 48 MP sensors will utilize binning down to 12 MP.
Device Examples:
- Samsung Galaxy A10e (2025 re-release) — $129, 4/64 GB, 5.8" HD+.
- Xiaomi Redmi Go 3 — $139, 4/128 GB, 6.2" HD+.
8. Final Conclusion: Who is the Exynos 7884B Suitable For?
This processor is a choice for:
- Budget users who need a smartphone for calls, messaging, and YouTube.
- Backup devices — for travel or as a gadget for a child.
- Markets with slow 5G adoption — in countries in Asia, Africa, and parts of Eastern Europe.
Key Benefits:
- Price below $150.
- Reliability of Samsung architecture.
- Sufficient power for basic tasks.
Conclusion
The Exynos 7884B in 2025 is not a performance king but rather a "workhorse" for those who value simplicity and economy. If you are not chasing future technologies and are looking for a "daily driver" device, a smartphone based on this SoC will be a sensible choice. However, for gaming, 4K recording, or working with AI services, it’s worth considering more modern chips.
