Pentium 4405U Details

With a base clock speed of 2100 MHz and a maximum turbo frequency of 2900 MHz, the Intel Pentium 4405U is a mobile processor built on the Skylake microarchitecture using a 14 nm process. Released several years ago, it is now considered an older device, reflecting a design era when power efficiency and integrated graphics were prioritized in low-to-mid-tier laptops. Despite its age, the processor remains relevant for light computing tasks due to its 2-core, 4-thread configuration enabled by Intel's Hyper-Threading technology.

The Pentium 4405U features a 2 MiB L3 cache and 0.5 MiB of L2 cache, along with 0.125 MiB of L1 cache, distributed across its cores. It supports DDR4-2133, LPDDR3-1866, and DDR3L-1600 memory types, with a maximum memory capacity of 32 GiB and a peak memory bandwidth of 31.79 GiB/s. It operates within a 15 W TDP, making it suitable for thin-and-light notebooks where thermal constraints are a concern. The processor uses the FCBGA-1356 package and supports Intel's Enhanced SpeedStep and Turbo Boost 2.0 technologies, allowing for dynamic frequency adjustments based on workload.

Integrated into the design is the HD Graphics 510 GPU, which features 12 execution units and a base frequency of 300 MHz, capable of reaching up to 950 MHz in burst mode. This GPU supports up to three displays and is sufficient for basic multimedia playback and light graphical applications. The processor also supports a range of instruction sets, including AVX2, AES-NI, and SSE4.2, enabling efficient performance in modern software environments.

In benchmark testing, the Pentium 4405U achieves an overall score of 4304, ranking #1524 among 2060 processors. Its single-core score is 4189, placing it #1589, while its multicore score is 4476, ranking #1274. While these results are modest compared to modern high-performance CPUs, they reflect the processor's positioning as a low-power, cost-effective option for entry-level computing. It competes with older mobile processors such as the A10-6800K and the Core M 5Y10c, but trails behind more recent models like the Core i5-560M and the A6-5400K.

As of March 2026, the Pentium 4405U is best suited for users who require basic productivity tasks, web browsing, and media consumption without the need for heavy multitasking or intensive applications. Its low TDP and integrated graphics make it a practical choice for portable devices where battery life and thermal management are key considerations. However, for users seeking higher performance, the processor's age and limited capabilities place it well behind current-generation offerings from both Intel and AMD.
