Intel Pentium 4405Y: A Compact Processor for Ultraportable Devices

April 2025

Introduction

The Intel Pentium 4405Y is a processor released in 2016, still found in budget ultrabooks and hybrid devices. Despite its age, it remains relevant for certain use cases due to its extremely low power consumption and compact form factor. In this article, we will discuss who this chip is suitable for in 2025, how it handles tasks, and what to pay attention to when purchasing a laptop with it.

Architecture and Manufacturing Process

Skylake Features

The processor is built on the Skylake microarchitecture (6th generation Intel Core) with a 14nm manufacturing process. This has allowed for reduced power consumption without significant performance losses compared to previous generations (Broadwell).

- Cores and Threads: 2 cores with Hyper-Threading support (4 threads).

- Clock Frequencies: Base frequency is 1.5 GHz. Turbo mode is absent, which limits performance under load.

- Integrated Graphics: Intel HD Graphics 515 with 24 execution units (EU) and a frequency of up to 850 MHz. Supports 4K via DisplayPort, hardware decoding of H.265/HEVC.

The iGPU is suitable for external monitor output and light graphical tasks but is not designed for modern gaming.

Power Consumption and TDP

TDP of 6 Watts is a key feature of the processor. This allows:

- Passive cooling (no fans), making devices silent.

- Integration of the chip into thin ultrabooks (e.g., Dell Latitude 5175) and convertible tablets.

However, the low TDP imposes limitations:

- Fixed frequencies—no headroom for short bursts of load.

- Possible throttling during prolonged use due to overheating in compact cases.

Performance in Real Tasks

Office Work and Multimedia

- Office applications (Word, Excel, browsers with 10+ tabs): The processor handles them but may stutter when working on PDF files and during video calls.

- Video playback: 4K@30fps (H.265) plays without issues thanks to hardware decoding. Streaming YouTube in Full HD is also stable.

- Photo/Video editing: Only basic tasks in Lightroom or Shotcut. Rendering 1080p video will take 3-4 times longer than on a Core i5 12th generation.

Gaming

- Integrated HD 515 graphics: Runs only older or less demanding games at low settings:

- Minecraft (30-40 FPS at 720p);

- Dota 2 (25-30 FPS at 720p, minimum settings);

- Overwatch (not recommended—less than 20 FPS).

The processor is not suitable for gaming but can run retro titles via emulators (for example, PlayStation 1).

Use Cases

Pentium 4405Y is suitable for:

1. Students—text work, online courses, lecture viewing.

2. Office workers—email, documents, video conferencing.

3. Digital detox users—devices with limited functionality to focus on tasks.

Not suitable for:

- Programming (except for web development on lightweight IDEs);

- Video editing/3D modeling;

- Modern games.

Example device for 2025: Chuwi Minibook X with an 8.9" screen priced at $450–$550.

Battery Life

Battery life depends on battery capacity and OS optimization:

- With a capacity of 40 Wh (typical for ultrabooks)—6–8 hours in web surfing mode.

- In standby mode (documents, reading)—up to 10 hours.

Power-saving technologies:

- Intel Speed Shift—rapid switching between C-states to reduce energy consumption.

- Passive cooling—absence of a fan saves battery life.

Tip: In Windows 11/12, use "Battery Saver" mode and disable background applications.

Comparison with Competitors

AMD

- Athlon Silver 3050e (2020, 6W, 2 cores/2 threads): Weaker in multithreaded tasks but cheaper. Suitable for Chrome OS devices.

- Ryzen 3 7320U (2023, Zen 2, 15W): Significantly more powerful but requires active cooling.

Apple

- Apple M1 (2020): Outperforms the Pentium 4405Y by 4-5 times in performance but devices with M1 start at $800.

Previous Intel Generations

- Pentium 3805Y (Broadwell): 10-15% slower due to older architecture.

- Celeron N5100 (Jasper Lake): Comparable in power but released later (2021) and supports Wi-Fi 6.

Pros and Cons

Strengths:

- Low power consumption and silence.

- Affordable device prices ($400–$600).

- Support for 4K output.

Weaknesses:

- Low performance for multitasking.

- Outdated architecture (competitors offer more cores and higher frequencies).

- Limited support lifespan (drivers and updates ceased in 2022).

Laptop Selection Recommendations

1. Type of Device: Ultrabook or convertible tablet (e.g., HP Elite x2 1012 G1).

2. RAM: Minimum 8GB—4GB will not be enough even for Windows 11.

3. Storage: Only SSD (256GB and more).

4. Screen: IPS matrix with a resolution of 1920x1080.

5. Ports: USB-C with Power Delivery support for fast charging.

Important: Check if the OS is optimized for low CPU (Windows 11 SE, Linux Mint).

Final Conclusion

The Intel Pentium 4405Y in 2025 is a choice for those who:

- Seek an ultra-light and quiet laptop for basic tasks.

- Are not willing to overpay for performance (devices under $600).

- Value battery life (6–8 hours of use).

Alternatives: If the budget allows $700–$900, consider laptops with Intel Core i3-N305 or AMD Ryzen 3 8300U. They provide better performance while maintaining battery efficiency.

Summary: The Pentium 4405Y is an outdated but functional option for undemanding users. Before purchasing, test the device under your expected load: open 15 tabs in a browser and launch Zoom. If everything runs smoothly—feel free to buy!
