Intel Celeron 3755U: Budget Processor for Basic Tasks in 2025

Updated: April 2025

Introduction

The Intel Celeron 3755U processor, released in 2015, is still found in ultra-budget laptops costing from $200. Despite its outdated architecture, it remains a choice for those prioritizing minimal price. Let’s explore who this solution is suitable for and who might want to look for alternatives.

Architecture and Process Technology

Broadwell: 14nm and Two Cores

The Celeron 3755U is built on the Broadwell architecture (5th generation Intel Core). The 14nm process technology allowed for lower power consumption, but even for 2015, this was a modest model:

- 2 Cores, 2 Threads — The lack of Hyper-Threading limits multitasking.

- Base Frequency: 1.7 GHz — Turbo Boost is not supported.

- L3 Cache: 2 MB — The small cache size slows down processing of complex tasks.

- Integrated Graphics: Intel HD Graphics (Broadwell) — 12 EU (Execution Units), frequency 100–850 MHz.

The iGPU manages 1080p display output and H.264 video decoding, but it doesn’t have enough power for 4K or modern codecs (AV1).

Power Consumption and TDP

TDP 15W — a typical figure for ultrabooks. This allows for:

- Use of passive cooling or compact coolers.

- Creation of thin laptops (up to 18mm).

- Reduced noise levels.

However, under peak load (for example, running a browser with 20+ tabs), the processor may overheat in devices with poor cooling systems.

Performance in Real Tasks

Office Work

- Documents, Spreadsheets: Microsoft Office, Google Workspace run without lags, but opening 5–7 browser tabs simultaneously plus messengers can cause stuttering.

- Video Calls: Zoom/Google Meet at 720p is acceptable, but 1080p with background filters becomes a burden.

Multimedia

- Video: Playback of 1080p@60 FPS (H.264) is smooth. 4K or H.265 may encounter failures without hardware decoding.

- Photo Editors: Lightroom or Photoshop can only manage basic retouching.

Gaming

- CS:GO: 720p, low settings — 20–25 FPS.

- Minecraft (without shaders): 30–40 FPS.

- Modern games (2023–2025) — will not run.

Turbo Mode: Does not exist. The processor does not accelerate under load, which limits performance.

Use Cases

Who the Celeron 3755U is Suitable For:

- Students: for studying, text work, and online courses.

- Seniors: browsing the internet, social media interaction.

- As a secondary laptop for travel.

Who it is Not Suitable For:

- Gamers.

- Designers, programmers, video editors.

- Users working with "heavy" applications (for example, Figma, AutoCAD).

Battery Life

- Battery Life: 6–8 hours with a battery capacity of 40–45 Wh (web surfing, office tasks).

- Power-Saving Technologies:

- Intel SpeedStep — dynamic frequency scaling.

- C-States — disabling unused cores.

- Tip: To extend battery life, disable background applications and reduce screen brightness.

Comparison with Competitors

AMD Athlon Silver 3050U (2020)

- 2 cores / 4 threads, Vega 2 GPU.

- 20–30% more performance in multitasking.

- Laptops from $350.

Intel Pentium Silver N6000 (2021)

- 4 cores / 4 threads, 10nm, UHD Graphics.

- Supports 4K@60 FPS.

- Price: from $400.

Apple M1 (2020)

- Does not compete on price (devices start from $800), but demonstrates how outdated the Celeron 3755U is.

Conclusion: The Celeron 3755U lags behind even budget processors from 2020–2022 years, but it wins in price.

Pros and Cons

Pros:

- Laptop prices from $200

- Energy-efficient

- Quiet operation

Cons:

- Low performance

- No support for modern technologies (AV1, Wi-Fi 6)

- Only 2 cores / 2 threads

Recommendations for Choosing a Laptop

- Device Type: Ultrabook or compact laptop with a screen size of 11–14 inches.

- Essential Parameters:

- SSD (256 GB) — HDD will slow down the system.

- 8 GB RAM — 4 GB is inadequate even for Windows 11.

- IPS Screen — TN panels worsen color reproduction.

- Avoid: Laptops with a resolution above 1080p — the processor cannot handle it.

Examples of 2025 Models:

- HP Stream 14 ($229): 4 GB RAM, 64 GB eMMC, 14″ HD screen.

- Lenovo IdeaPad Slim 3 ($279): 8 GB RAM, 128 GB SSD, 15.6″ HD.

Final Conclusion

Intel Celeron 3755U in 2025 is suitable for:

- Users with minimal requirements.

- Those looking for the cheapest new laptop.

- Situations where battery life and quiet operation are more important than speed.

Key Benefits:

- Low price.

- Sufficient for basic tasks.

- Compactness and portability.

Recommendation: If budget allows, add $100–150 to choose laptops with Intel Pentium Silver or AMD Athlon Silver — it will significantly extend the device's lifespan.
