Core i5-10400H Details

For users seeking a capable mobile processor with strong single-core performance and integrated graphics, the Intel Core i5-10400H offers a compelling option, particularly for those who prioritize efficiency and responsiveness in everyday computing. Launched in April 2020, this mobile processor is based on Intel’s Comet Lake-H architecture and is designed for laptops and thin-and-light systems requiring balanced performance without the need for a discrete GPU. While now over four years old, the i5-10400H remains relevant in entry-level and mid-tier systems due to its strong single-threaded capabilities and efficient power consumption.

The processor features a 4-core, 8-thread design, thanks to Intel Hyper-Threading, allowing it to handle multitasking and modern workloads effectively. With a base clock of 2.6 GHz and a turbo frequency of up to 4.6 GHz, the i5-10400H delivers impressive burst performance for short, intensive tasks. It is built on a 14 nm process and includes 6 MB of L3 cache, which helps maintain high data throughput during performance-critical operations. The chip operates at a TDP of 45 W, making it suitable for systems with modest cooling solutions.

Memory support includes DDR4-2933 in dual-channel mode, providing a maximum memory bandwidth of 45.8 GB/s, which contributes to its strong overall performance. The i5-10400H supports up to 128 GB of RAM and integrates Intel UHD Graphics, which operates at a base frequency of 350 MHz and can boost to 1.1 GHz. The integrated GPU supports up to three displays and is capable of handling light gaming and multimedia tasks, though it falls short of dedicated graphics cards.

In benchmark testing, the i5-10400H achieves a single-core score of 5,899, placing it at #308 among 2,060 CPUs, and a multicore score of 4,938, ranking it #688. Its overall score of 5,515 ranks it #471 out of 2,060 processors. These results indicate that while the i5-10400H is no longer competitive with modern high-end CPUs, it holds its own against many mid-range and older processors. Notably, it outperforms several newer mobile chips like the Core i5-1035G7 and the Core i7-9850H, highlighting its enduring single-core strength.

The processor supports a wide range of technologies, including Intel’s AVX, AVX2, AES-NI, and Hyper-Threading, making it suitable for applications that benefit from SIMD instructions and multithreading. It also supports virtualization technologies like VT-x and VT-d, enhancing its utility in professional and development environments. However, its locked multiplier limits overclocking potential, a common trait in Intel’s mainstream mobile processors.

As of March 2026, the Core i5-10400H is best suited for users who need reliable performance in portable devices, such as students, office workers, or casual content creators. While it may not handle modern AAA games or intensive content creation workloads efficiently, its balanced mix of performance, power efficiency, and integrated graphics makes it a solid choice for everyday computing needs.
