Core i5-6440HQ Details

As of March 2026, the Intel Core i5-6440HQ remains a mobile processor from the Skylake generation, originally launched in 2015. Though now over a decade old, it continues to serve as a mid-tier option in legacy systems and budget laptops, particularly where integrated graphics and power efficiency are prioritized. Built on Intel’s 14 nm process and based on the Skylake microarchitecture, this quad-core CPU features a base clock of 2.6 GHz and a maximum turbo frequency of 3.5 GHz, delivering a balanced performance profile for everyday computing and light productivity tasks.

The processor supports up to 64 GiB of DDR4-2133 and DDR3L-1600 memory across two channels, with a maximum memory bandwidth of 31.79 GiB/s. It includes 6 MiB of L3 cache and 1 MiB of L2 cache, with 0.125 MiB each of L1 data and instruction cache. The integrated HD Graphics 530 GPU offers 24 execution units, with a base frequency of 350 MHz and a dynamic boost up to 950 MHz, enabling basic multimedia playback and light gaming. With a TDP of 45 W and support for Intel’s Turbo Boost 2.0 and Enhanced SpeedStep, the i5-6440HQ provides a reasonable trade-off between performance and thermal efficiency.

In benchmark testing, the Core i5-6440HQ achieves a single-core score of 5,229, ranking #783 out of 2,060 processors, and a multicore score of 4,776, placing it at #878. Its overall score of 5,048 lands it at #834 in the broader ranking, indicating solid performance for its era but significant gaps compared to modern CPUs. The single-core performance is notably strong, often outperforming newer processors in single-threaded applications, while its multicore capabilities are less competitive due to its older architecture and lower core counts.

The i5-6440HQ supports a wide range of Intel technologies, including AVX2, AES-NI, and Intel VT-x for virtualization, as well as integrated security features like Intel Secure Key and TXT. It also supports ECC memory, though this is rare in consumer mobile platforms. Despite its age, the processor remains relevant in environments where legacy software compatibility is essential, and its support for DDR4-2133 memory ensures it can still run efficiently on modern systems.

In conclusion, the Core i5-6440HQ is best suited for general-purpose computing, office work, and multimedia use in older laptops or systems where upgrade options are limited. While it lacks the performance and efficiency of modern processors, its reliability and broad compatibility make it a durable choice in the right context. For users seeking higher performance, upgrading to a newer generation Intel or AMD processor is strongly recommended.
