Pentium 4405Y Details

With a base clock speed of 1.5 GHz and a TDP of just 6 watts, the Intel Pentium 4405Y stands out as a power-efficient mobile processor built on the Skylake microarchitecture. Released in 2016, it's now considered a legacy device, but its design still holds relevance for low-power computing scenarios such as thin-and-light laptops and fanless systems. Despite its age, the processor maintains a functional presence in the market due to its integrated HD Graphics 515 GPU and support for modern memory standards like LPDDR3-1866.

The Pentium 4405Y features a dual-core design with four threads, thanks to Intel's Hyper-Threading technology, enabling it to handle basic multitasking efficiently. It operates at a base frequency of 1.5 GHz, with a maximum turbo frequency of 2.8 GHz, though this is limited by its 6 W TDP. The processor is fabricated on a 14 nm process and includes 2 MiB of L3 cache, 0.5 MiB of L2 cache, and 0.125 MiB of L1 cache, ensuring adequate data access speeds for its intended use cases. It supports up to 16 GB of DDR3L-1600 or LPDDR3-1866 memory, delivering a maximum bandwidth of 27.81 GiB/s.

Integrated into the chip is Intel's HD Graphics 515 GPU, featuring 24 execution units and a base frequency of 300 MHz, with a burst frequency of up to 800 MHz. This GPU supports up to three displays and is capable of handling standard multimedia playback and light gaming. The processor also includes a range of Intel-specific features such as AES-NI for encryption, AVX2 for vector processing, and Intel VT-x for virtualization, making it suitable for enterprise and security-oriented applications.

In benchmark testing, the Pentium 4405Y achieves an overall score of 4116, placing it at #1785 among 2060 processors. Its single-core score of 3960 ranks it at #1788, while its multicore performance scores 4349, ranking #1585. These results indicate that while the processor is competitive with some older dual-core CPUs like the Core 2 Duo T6400 and Celeron G550, it lags significantly behind modern mainstream processors. In comparison to top-tier chips like the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, the performance gap is substantial, underscoring its position in the lower end of the performance spectrum.

As of March 2026, the Pentium 4405Y is best suited for basic computing tasks such as web browsing, office applications, and media consumption in ultra-portable devices. Its low power consumption and integrated graphics make it a viable option for users prioritizing battery life and portability over raw performance. While it cannot compete with current-generation CPUs in gaming or content creation, it remains a reliable choice for lightweight productivity workloads in older or budget-oriented systems.
