Intel Celeron N4000: Budget Processor for Basic Tasks. A Comprehensive Review
April 2025
Architecture and Process Technology: Gemini Lake in Detail
The Intel Celeron N4000 is a dual-core processor with two threads, built on a 14nm process technology. It belongs to the Gemini Lake generation, which debuted in 2017, but still appears in budget laptops due to its low cost and energy efficiency.
Cores and Frequency
- 2 cores, 2 threads: The Goldmont Plus architecture is optimized for low-power devices.
- Base frequency: 1.1 GHz. Turbo mode is absent—this processor cannot dynamically increase its frequency.
- Integrated graphics: Intel UHD Graphics 600 with a base frequency of 200 MHz (up to 650 MHz peak). It supports 4K output via HDMI 2.0, but is not suitable for gaming or video editing tasks.
Memory and Cache
- Supports single-channel LPDDR4-2400 or DDR4-2400 memory. Maximum capacity is 8 GB.
- L2 Cache: 4 MB.
Architecture Features
- Emphasis on power savings: ideal for devices with passive cooling.
- Supports hardware video decoding for VP9 and H.265—improving 4K streaming content playback.
Power Consumption and TDP: Why 5 Watts Matter
The processor's TDP (Thermal Design Power) is 5 Watts. This means it generates minimal heat, allowing for:
- Use of passive cooling (fanless), making laptops silent.
- Installation of the processor in compact devices: mini-PCs, ultrabooks, tablets.
Real Implications of Low TDP
- Laptops with the N4000 often have a slim profile (15–18 mm) and weigh less than 1.5 kg.
- No risk of overheating even during prolonged usage.
Performance: What Can You Do with the Celeron N4000
Geekbench 6 test results (339/474) show that the processor is suitable only for basic tasks:
Office Work
- Documents (Word, Excel), browser with 5–7 tabs, Zoom conferences—everything runs smoothly, but with limitations:
- Running Photoshop or heavy web applications (like Figma) simultaneously will cause lags.
Multimedia
- Watching YouTube at 1080p/4K: hardware decoding ensures smoothness.
- Simple video editing in Shotcut or similar programs is possible, but rendering will take 3–4 times longer than on a Core i3.
Gaming
- Only light games: Minecraft on low settings (20–30 FPS), Stardew Valley, browser games.
- Fortnite or GTA V are not options: the Intel UHD 600 cannot handle even the lowest settings.
Turbo Mode
Absent. The frequency is fixed at 1.1 GHz, limiting performance in "heavy" scenarios.
Use Cases: Who Should Consider This Processor
1. Students: For lectures, text tasks, and online courses.
2. Seniors: Simple interface, long battery life.
3. Second Laptop: For travel or work in cafes.
4. Digital Kiosks/Terminals: Low cost and reliability.
Who Should Look Elsewhere
- Gamers, designers, programmers.
Battery Life: How the N4000 Saves Power
Laptops with this processor often come equipped with batteries of 35–45 Wh, allowing for 8–12 hours of operation under:
- 50% screen brightness.
- Active use of browsers and office applications.
Power-Saving Technologies
- Intel Speed Shift: Dynamic frequency management to reduce power consumption.
- C6/C7 States: Deep sleep states for cores during idle periods.
Tip: Disable background applications and use browsers like Edge or Chrome with power-saving mode enabled.
Comparison with Competitors: What to Choose Instead of the N4000
- AMD Athlon Silver 3050e: 2 cores/4 threads, Vega 3 GPU. Better for multitasking, but TDP is 6W (laptops starting at $300).
- Intel Pentium Silver N5030: 4 cores, 1.1–2.8 GHz. 20–30% more performance but priced higher ($350+).
- Apple M1 (in basic iPads): Absolute leader in performance, but starting price is $499.
Conclusion: The Celeron N4000 is the cheapest option, but it’s only advisable when on a strict budget.
Pros and Cons
Strengths
- Laptop prices starting from $200.
- Silent operation (fanless).
- Support for 4K video.
Weaknesses
- Slow even for Windows 11.
- No upgrade options: memory is often soldered on the board.
- Limited multitasking capabilities.
Recommendations for Choosing a Laptop
1. Type of Device: Ultrabook or convertible with a touchscreen. Avoid “gaming” models with this CPU—it's a marketing gimmick.
2. RAM: At least 8 GB. Models with 4 GB will lag, even in browsers.
3. Storage: Only SSD (128–256 GB). HDD will slow down the system.
4. Display: IPS panel with a resolution of 1920×1080.
Examples of 2025 Models
- ASUS Laptop Go 11 ($249): 11.6" HD, 8 GB, 128 GB SSD.
- Lenovo IdeaPad Slim 3 ($279): 14" FHD, 8 GB, 256 GB SSD.
Final Verdict: Is It Worth Buying?
The Intel Celeron N4000 is a processor for those who value battery life and minimalism. It is the ideal choice for:
- Budget laptops under $300.
- Tasks that do not require high performance.
Key Benefits:
- Affordable price.
- Compact and quiet operation.
- Sufficient for basic needs.
If your budget allows you to add $100–150, it's better to choose a model with AMD Ryzen 3 or Intel Pentium Silver—this will significantly enhance the device's capabilities. However, for emailing, Netflix, and document work, the Celeron N4000 remains a viable option even in 2025.
