Intel® Atom™ x6425RE

The Intel Atom x6425RE is a embedded processor with 4 cores and 4 threads, built on the Elkhart Lake architecture. It launched in Jan 2021. A 1.5-MB L3 cache backs the cores (4.4 MB per core). It addresses LPDDR4, DDR4 memory up to 32 GB across 4 channels. The chip drops into the FCBGA1493 socket and exposes PCIe 3.0 (8 lanes). Rated TDP is 12 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT).

The Intel Atom x6425RE scores 997 in single-core performance and 2,817 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,676 for overall performance, 3,227 for productivity performance, 3,344 for creator performance, 2,711 for engineering performance and 3,695 for gaming performance. Its multi-core throughput works out to 704 per core, 704 per thread and 235 per watt. Its computed efficiency index is 484. Its performance index is 21, so its overall performance is 79% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Atom x6425RE scores 9,020 in integer math, 5,400 in floating-point math, 36,890 in compression, 2,168 in cryptography, 206 in physics simulation, 1,126 in vector SIMD, 9 in the prime sieve and 5,314 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 85% below in integer math, 88% below in floating-point math, 84% below in compression, 81% below in cryptography, 81% below in physics simulation, 93% below in vector SIMD, 87% below in the prime sieve and 77% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Atom x6425RE has 4 physical cores and runs 4 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.90 GHz.

The Intel Atom x6425RE is a embedded processor, belongs to the Intel Atom X family, uses the Elkhart Lake architecture, carries the codename Elkhart Lake and is manufactured on a 10 nm process. It launched in Jan 2021.

The Intel Atom x6425RE has 4 MB of L1 cache, 12 MB of L2 cache and 1.5 MB of L3 cache. That adds up to about 17.5 MB of cache, or 4.38 MB per core.

The Intel Atom x6425RE has a 3-level cache hierarchy: L1 at 4 MB, L2 at 12 MB and L3 at 1.5 MB. L2 is the largest level and makes up about 69% of the cache listed here.

The Intel Atom x6425RE supports LPDDR4, DDR4 memory, addresses up to 32 GB of memory, uses 4 memory channels and runs memory at up to 4,267 MT/s. It does not support DDR5 memory.

The Intel Atom x6425RE includes integrated graphics (Intel UHD Graphics for 10th Gen Intel Processors) and clocks the graphics up to 0.40 GHz.

The Intel Atom x6425RE uses the FCBGA1493 socket, supports PCI Express 3.0 and provides up to 8 PCIe lanes.
