Core i5-9400H Details

Built on Intel's Coffee Lake microarchitecture and fabricated on a 14 nm process, the Core i5-9400H is a mobile processor designed for high-performance laptops. As of March 2026, this CPU is considered a legacy device, having been released in 2019, but it remains relevant in the mid-tier mobile market for users seeking a balance of performance and power efficiency. The processor is part of Intel’s 9th generation lineup, built to deliver a strong performance-per-watt ratio in thin-and-light and performance-oriented systems.

The Core i5-9400H features a quad-core design with eight threads, enabled by Intel's Hyper-Threading technology, allowing it to handle multithreaded workloads efficiently. It operates at a base frequency of 2.5 GHz, with a maximum turbo frequency of 4.3 GHz, providing a significant boost in single-threaded performance when needed. The chip is equipped with 8 MiB of L3 cache and 1 MiB of L2 cache, complemented by 0.25 MiB of L1 cache split between instruction and data. This cache hierarchy ensures fast data access, which is crucial for both productivity and gaming workloads.

With a TDP of 45 W and a downclock option to 35 W, the i5-9400H offers flexible power management for laptops that prioritize battery life. It supports dual-channel DDR4-2666 and LPDDR3-2133 memory, delivering a maximum memory bandwidth of 39.74 GiB/s. The processor uses the FCBGA-1440 package and is compatible with the 300 series chipset, supporting PCIe 3.0 with up to 16 lanes. Its integrated UHD Graphics 630 GPU features 24 execution units and can boost up to 1.1 GHz, capable of driving up to three displays simultaneously—making it suitable for light multimedia and office use without a discrete GPU.

The i5-9400H supports a wide array of Intel technologies, including Intel Speed Shift, Turbo Boost 2.0, and Intel vPro, which enhance responsiveness and security. It also includes advanced instruction sets such as AVX2, AES-NI, and FMA3, which improve performance in encryption, compression, and scientific computing. Additionally, it supports Intel's virtualization technologies (VT-x, VT-d) and secure boot features, making it suitable for enterprise environments.

In benchmark testing, the Core i5-9400H achieves an overall score of 5149, ranking #746 out of 2060 processors. Its single-core score of 5301 places it at #724, while its multicore score of 4922 ranks it #703. Compared to its contemporaries, it performs slightly behind higher-end mobile CPUs like the Core i7-7700HQ but outpaces many budget and older processors such as the Core i5-7500. In the broader market, it trails far behind modern high-end CPUs like the Core Ultra 9 285K or Ryzen Threadripper PRO 9995WX, but remains competitive in its segment.

As of March 2026, the Core i5-9400H is best suited for mainstream mobile users who require a reliable processor for productivity, multimedia, and casual gaming. Its efficiency, combined with strong single-core performance and integrated graphics, makes it a solid choice for laptops where discrete GPU power is unnecessary. While it no longer competes with the latest mobile processors, it still offers dependable performance for everyday computing tasks.
