Core i5-9400T Details

The Intel Core i5-9400T stands out for its efficiency and balanced performance, making it a compelling option for low-power desktop systems. Launched in September 2018, this processor is built on Intel’s Coffee Lake Refresh architecture and is designed for mainstream desktop use. Despite being over seven years old, it remains relevant in applications where power consumption and thermal output are critical, such as small form-factor PCs and office workstations. Its 35 W TDP, with a downclocked 25 W mode at 1.2 GHz, ensures minimal energy draw, while still delivering respectable performance for everyday computing tasks.

Featuring six cores and six threads, the Core i5-9400T operates at a base frequency of 1.8 GHz and can boost up to 3.4 GHz under load, leveraging Intel’s Turbo Boost 2.0 technology. It is manufactured on a 14 nm process and includes 9 MB of L3 cache, enhancing data access speeds. The processor supports dual-channel DDR4-2666 memory and is compatible with the LGA-1151 socket, ensuring broad system compatibility. With a maximum memory capacity of 128 GB and a memory bandwidth of 42.7 GB/s, it offers solid performance for general productivity and light multitasking.

Integrated graphics are provided by the UHD Graphics 630, featuring 24 execution units and a max frequency of 1.05 GHz. This GPU supports up to three displays and can handle basic multimedia playback and light gaming, eliminating the need for a discrete graphics card in many scenarios. The processor also includes a wide range of modern instruction sets, such as AVX, AVX2, and AES-NI, improving performance in encryption, compression, and scientific computing workloads.

In benchmark testing, the Core i5-9400T achieves an Overall Score of 5,088, placing it at #802 out of 2,060 processors. Its Singlecore Score of 5,198 ranks it at #809, indicating strong performance per core, while its Multicore Score of 4,924 places it at #700, reflecting its ability to handle multi-threaded applications. The processor compares favorably with several contemporary Intel and AMD offerings, including the Core i5-7600 and Xeon E3-1260L v5, but trails behind higher-end models like the Core i7-6700HQ and Ryzen 5 2600H. Its performance is most competitive in the low-to-mid-tier desktop segment.

As of March 2026, the Core i5-9400T is best suited for users who prioritize energy efficiency, quiet operation, and cost-effective computing. While it is no longer competitive in high-performance or gaming environments, it remains a viable choice for business desktops, home office systems, and embedded applications where integrated graphics and low thermal design are essential. Its longevity and reliability make it a practical option for users seeking a stable, power-efficient solution without the need for cutting-edge performance.
