Benchmarks & Specs

Last updated:
The Intel Core i5-9400T is a processor from the Coffee Lake S Refresh generation, primarily notable for its special design. This chip was designed for efficiency, making it an excellent choice for systems with a small footprint or a desire for quiet operation. Manufactured using the 14nm process, it offers a convincing balance of performance and energy efficiency.

Particularly noteworthy is the integrated Intel UHD Graphics 630. It enables the construction of computers without a dedicated graphics card, which lowers costs and reduces power consumption. For everyday tasks such as office applications, web browsing, or streaming media content, the Intel Core i5-9400T still delivers absolutely sufficient performance today.

The 9 MB Level 3 cache contributes noticeably to a smoother execution of programs. We have seen that it is still very well suited for many home applications and as a basis for HTPCs. The components are connected via PCIe 3.0. This is perfectly adequate for most application areas for which this processor is intended.

It may not represent the absolute peak of performance, but its reliability and efficiency are definitely plus points.
  • Energy-efficient and quiet
  • Integrated Intel UHD Graphics 630
  • 9 MB Level 3 Cache
  • Suitable for everyday tasks and HTPCs
