Summary

The Intel Pentium 4405U is a mobile processor that was once a very reasonable choice. It belongs to the Skylake U generation and was manufactured using the then-modern 14 nm process. One of its particular strengths is its excellent energy efficiency. This made it an ideal companion for notebooks where battery life is crucial.

Even today, this processor delivers surprisingly solid performance for basic tasks. The integrated Intel HD Graphics 510 enables smooth display for everyday multimedia applications. We found that the 2 MB Level 3 cache effectively supports data processing. The Pentium 4405U is still well suited for common office work, surfing the internet, or e-mailing.

It formed a reliable foundation for many mobile devices of its time. The maximum memory bandwidth of 34 GB/s ensures a good data flow. It was and is a solid processor for everyday mobile use.
