Intel Atom x6425RE vs Intel Processor N100

The Intel Atom x6425RE (Elkhart Lake) was developed for embedded systems and industrial IoT applications that require reliability and efficiency.

The Intel Processor N100 (Alder Lake N) targets energy-efficient entry-level laptops, mini-PCs, and edge devices.

Both processors are manufactured by Intel using the 10 nm process and feature 4 cores and 4 threads. The Intel Atom x6425RE offers 2 MB of Level 2 Cache and PCIe 3.0 with a high memory bandwidth of 136 GB/s. The Intel Processor N100 has a larger 4 MB Level 2 and 6 MB Level 3 Cache, but a lower maximum memory bandwidth of 38 GB/s.

In terms of computing performance, the Intel Processor N100 significantly outperforms the Intel Atom x6425RE in single-core and multi-core benchmarks, which is due to its more modern architecture. These performance differences are substantial. Neither processor is primarily designed for gaming. The Intel Atom x6425RE with Intel UHD Graphics 10th Gen (32 EU) could have an advantage over the Intel UHD Graphics (24 EUs) of the Intel Processor N100 in very light graphics applications due to its significantly higher memory bandwidth of 136 GB/s, despite the latter's newer graphics core architecture.

The Intel Processor N100 is more energy-efficient with a TDP of 6 Watts than the Intel Atom x6425RE with 10 Watts, making it ideal for fanless or low-power systems. Regarding price-performance ratio, the Intel Processor N100 offers superior performance per watt for modern, general computing tasks.

The Intel Atom x6425RE remains relevant for specific industrial applications with high memory bandwidth requirements. In summary, the Intel Atom x6425RE is ideal for specialized industrial applications with high memory bandwidth requirements for the integrated graphics unit. The Intel Processor N100 is the better choice for modern, energy-efficient systems that require higher computing performance for everyday tasks.
