Intel Core i5-9400T vs Intel Processor N100

The Intel Core i5-9400T, introduced in the second quarter of 2019, is based on the 14 nm Coffee Lake S Refresh architecture.

With 6 cores and 6 threads, as well as a 9 MB Level 3 cache, it offers solid all-round performance for productivity and moderate workloads. Its Thermal Design Power (TDP) is 35 Watts. The integrated Intel UHD Graphics 630 with a maximum memory bandwidth of 43 GB/s serves for basic graphical tasks. It shows significantly higher multi-core performance and is primarily found on the used market.

The Intel Processor N100, introduced in the first quarter of 2023, uses the more advanced 10 nm Alder Lake N architecture with 4 efficiency cores and 4 threads.

It has 4 MB Level 2 and 6 MB Level 3 cache and is designed for maximum energy efficiency. Its very low TDP of 6 Watts makes it ideal for fanless systems and thin clients. The integrated Intel UHD Graphics 24 EUs (Alder Lake) offers an efficient graphics solution for media playback and very light gaming, supported by a maximum memory bandwidth of 38 GB/s.

Single-core performance is close to the Intel Core i5-9400T, but multi-core performance is lower. For users seeking stronger multi-core performance in an existing system, the Intel Core i5-9400T is the more suitable choice. If extreme energy efficiency, silent operation, and cost-efficiency for basic office tasks or as an HTPC are paramount, the Intel Processor N100 is the superior option.
