Benchmarks & Specs

Last updated:
The Intel Core i5-6400T processor is based on the Skylake S architecture from Intel, which represented an important advancement at the time. This generation was known for its high efficiency and offered solid overall performance in everyday use. It was manufactured using the then-advanced 14-nm technology.

A particularly noteworthy feature is the integrated Intel HD Graphics 530. It made the processor an extremely versatile choice for many computer systems. Users appreciated the ability to forgo an additional dedicated graphics card. It was always perfectly adequate for common office applications, streaming media, or image editing.

Surfing the internet was also always smooth and reliable with it. With its 6 MB Level 3 Cache, frequently needed data was quickly provided. This contributed to a responsive system. The support of PCIe 3.0 also enabled fast connections for expansion cards. For example, modern SSDs and various peripherals could be optimally connected.

This processor remains a functional choice even today. It is well suited for numerous standard applications and offers a solid foundation. We found its balance at the time to be very convincing.
  • Skylake S architecture for efficiency and solid performance
  • Integrated Intel HD Graphics 530 for versatile use
  • 14 nm manufacturing for good efficiency
  • PCIe 3.0 support for connectivity
