Intel Atom x7433RE vs Intel Atom x6425RE

The Intel Atom x6425RE, based on the Elkhart Lake architecture, is designed for energy-efficient embedded systems.

It is manufactured using a 10 nm process, features 2 MB of Level 2 cache, supports PCIe 3.0, and integrates a 10th Gen Intel UHD Graphics (32 EU) with 136 GB/s memory bandwidth. Its performance in single- and multi-core applications is fundamental. The Intel Atom x7433RE, utilizing the newer Amston Lake architecture, offers improved computing performance for similar markets.

Also manufactured using a 10 nm process, it has 2 MB of Level 2 cache and an additional 6 MB of Level 3 cache. It supports PCIe 3.0. The integrated Intel UHD Graphics (Alder Lake) with 32 EUs is architecturally more modern but has a lower memory bandwidth of 38 GB/s. It exhibits significantly higher single- and multi-core performance.

Both Atom processors are designed for low power consumption and are not optimized for gaming. The Intel Atom x7433RE generally offers better computing performance, while the x6425RE leads in memory bandwidth. A precise price-performance evaluation requires market prices, but the higher performance of the x7433RE is clear.

For more demanding embedded applications, the Intel Atom x7433RE is the better choice. The Intel Atom x6425RE is a solid option for basic tasks where energy efficiency and specific memory bandwidth requirements are a priority.
