Intel Core i5-6400 vs Intel Processor N100

The Intel Core i5-6400, based on the Skylake S architecture, was manufactured in 2015 using the 14 nm process and targeted mainstream desktops.

It features 4 cores and 4 threads, as well as Intel HD Graphics 530. The maximum memory bandwidth is 34 GB/s, and it supports PCIe 3.0. It has 6 MB of Level 3 Cache. Compared to the Intel Processor N100, it shows comparable single-core and multi-core performance.

Its older graphics unit is less suitable for gaming. The higher TDP requires more active cooling. It is inexpensive on the used market but requires an older platform. The Intel Processor N100, with the Alder Lake N architecture, is a newer, energy-efficient processor manufactured using the 10 nm process for compact systems.

It also offers 4 cores and 4 threads (Gracemont cores) and Intel UHD Graphics 24 EUs (Alder Lake). The memory bandwidth is 38 GB/s with PCIe 3.0. It integrates 4 MB of Level 2 Cache and 6 MB of Level 3 Cache. Its single-core and multi-core performance is very similar to that of the Intel Core i5-6400, with a slight advantage.

The more modern iGPU offers marginally better gaming performance for very light games. Thanks to its low TDP, it is ideal for fanless systems. As a current model, it offers good value for money in mini PCs. In summary, the Intel Core i5-6400 provides a solid basic solution for existing, less demanding desktop applications.

The Intel Processor N100 stands out with modern efficiency and quiet operation in new, compact systems, with similar performance for everyday tasks.
