Intel Celeron 3765U: An Affordable Processor for Basic Tasks in 2025 – Is It Worth Considering?

Introduction

The Intel Celeron 3765U is part of the budget line of processors, released back in 2015 using the Broadwell architecture. Despite its age, laptops featuring this CPU can still be found on the market (especially in the sub-$300 segment). In this article, we will explore whether this chip is relevant in 2025, what tasks it can handle, and who should pay attention to it.

Architecture and Technical Specifications

14 nm and Broadwell Cores

The Celeron 3765U is built on a 14 nm process, which by 2025 is considered outdated (modern Intel and AMD processors use 7 nm or smaller). Its Broadwell-U architecture is designed for energy efficiency rather than high performance:

- 2 cores, 2 threads – the absence of Hyper-Threading limits multitasking.

- Base frequency: 1.9 GHz – Turbo mode is not supported.

- Integrated graphics: Intel HD Graphics (Broadwell) – 12 execution units, with a frequency of up to 800 MHz. It supports 4K video via HDMI 1.4 but is not suitable for gaming.

iGPU Features

The integrated graphics can handle H.264 and VP9 video decoding, which is sufficient for streaming YouTube at 1080p. However, its power is inadequate for gaming or rendering: even in Dota 2 at low settings, the FPS barely reaches 20-25 frames per second.

Power Consumption and TDP

15 W – A Balance Between Battery Life and Performance

With a TDP of 15 watts, this processor can be used in thin laptops and ultrabooks without active cooling. This reduces noise and weight but imposes limits on peak performance. In reality, the chip rarely reaches its maximum power consumption as its resources are quickly exhausted under load.

Power-Saving Technologies

- SpeedStep – dynamic frequency scaling to reduce power consumption.

- C-States – shutting down unused processor blocks during idle periods.

- Enhanced AVX2 instructions – accelerating tasks with minimal increases in energy consumption.

Performance in Real-World Tasks

Office Work and Web Surfing

The Celeron 3765U can handle basic scenarios:

- Working in Google Docs, Microsoft Word, and Excel.

- Browsing the web with 5-10 tabs open (Chrome, Firefox).

- Video calls on Zoom/Skype (with background optimization enabled).

Problems arise with:

- Simultaneous running of antivirus software and a browser with heavy websites (e.g., Figma).

- Attempting to open a PDF file larger than 100 MB.

Multimedia

- Video: 1080p/60 FPS playback – no issues. 4K/30 FPS – may experience stutters.

- Photo editors: GIMP or Photoshop with simple filters – slow, but functional. Neural network tools (e.g., background removal) – not recommended.

Gaming

Even less demanding games require lowered settings:

- CS:GO: 720p, minimum settings – 25-35 FPS.

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

- Stardew Valley, Terraria – stable 60 FPS.

For games in 2025, this processor is inadequate.

Usage Scenarios: Who Should Consider the Celeron 3765U?

Target Audience

1. Students: For working on texts, presentations, and online courses.

2. Retirees: Simple tasks – email, news, video.

3. Backup devices: An inexpensive laptop for travel.

Who Should Avoid It

- Gamers and video editors.

- Users working with "heavy" IDEs (Android Studio, PyCharm).

- Those using neural network tools (e.g., Stable Diffusion).

Battery Life: How Long Does the Laptop Last?

With a battery capacity of 40-45 Wh (typical for budget models), the operational time is:

- 6-8 hours – web surfing and office tasks.

- 4-5 hours – video playback via HDMI.

Tip: Choose laptops with energy-efficient displays (e.g., IPS matrices with 250 nits brightness). Avoid models with HDDs – SSDs reduce power consumption by 10-15%.

Comparison with Competitors

AMD Athlon Silver 3050U (2023)

- 2 cores / 4 threads, Vega 2 GPU.

- Geekbench 6: Single-Core – 520, Multi-Core – 1100.

- Laptop prices: starting from $350. Conclusion: Better performance for a slightly higher cost.

Apple M1 (2020)

- 8 cores (4+4), 7 nm, TDP 10 W.

- Geekbench 6: Single-Core – 2300, Multi-Core – 8300.

- Price: starting from $900. Conclusion: No comparison, but the price is three times higher.

Intel Celeron N5100 (2021)

- 4 cores / 4 threads, 10 nm, TDP 6 W.

- Geekbench 6: Single-Core – 650, Multi-Core – 1350.

- Price: starting from $320. Conclusion: A more modern, energy-efficient alternative.

Pros and Cons of the Celeron 3765U

Strengths

- Low price: Laptops from $250.

- Passive cooling: Quiet operation.

- Sufficient for basic tasks: If expectations are not too high.

Weaknesses

- Poor performance: Even for 2025 standards.

- No support for USB-C/Thunderbolt: Outdated ports (USB 3.0, HDMI 1.4).

- Limited upgrades: Often non-removable RAM and SSD.

Recommendations for Laptop Selection

Buying Criteria

1. RAM: At least 8 GB. Models with 4 GB will struggle even with Windows 11 Lite.

2. Storage: Only SSD (256 GB and above). HDDs "kill" speed.

3. Screen: Resolution 1920×1080. TN matrices should be avoided – low viewing angles.

4. Ports: Look for at least one USB 3.0 for external drives.

Examples of 2025 Models

- HP 14-dk1000: 14" FHD, 8 GB, 256 GB SSD – $279.

- Lenovo IdeaPad 1 Gen 7: 15.6" HD, 8 GB, 128 GB SSD – $269.

Final Conclusion

In 2025, the Celeron 3765U is a choice for those who are critically budget-conscious. This processor is suitable for:

- Buying a first laptop for a child.

- Using as a "typewriter" or a device for Zoom.

- Working with office applications without complex calculations.

Key advantages:

- Cost below $300.

- Good battery life.

- Compatibility with lightweight OS (Linux Lite, Chrome OS Flex).

Alternative: If the budget allows for an additional $50-100, consider laptops with the Intel N-series or AMD Athlon Silver – they will last longer and not disappoint in multitasking.
