Intel® Atom™ x6427FE

The Intel Atom x6427FE 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 (0.8 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 x6427FE scores 1,016 in single-core performance and 3,196 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,802 for overall performance, 3,500 for productivity performance, 3,587 for creator performance, 3,076 for engineering performance and 3,847 for gaming performance. Its multi-core throughput works out to 799 per core, 799 per thread and 266 per watt. Its computed efficiency index is 520. Its performance index is 22, so its overall performance is 78% 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 x6427FE scores 10,489 in integer math, 5,519 in floating-point math, 39,881 in compression, 2,360 in cryptography, 235 in physics simulation, 1,448 in vector SIMD, 9 in the prime sieve and 5,965 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 82% below in integer math, 88% below in floating-point math, 83% below in compression, 79% below in cryptography, 78% below in physics simulation, 91% below in vector SIMD, 87% below in the prime sieve and 74% 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 x6427FE 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 x6427FE 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 x6427FE has 256 KB of L1 cache, 1.50 MB of L2 cache and 1.5 MB of L3 cache. That adds up to about 3.3 MB of cache, or 0.81 MB per core. Each core has 384 KB of private L2 cache.

The Intel Atom x6427FE has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1.5 MB and L3 at 1.5 MB. L2 is the largest level and makes up about 46% of the cache listed here.

The Intel Atom x6427FE 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 x6427FE includes integrated graphics (Intel UHD Graphics for 10th Gen Intel Processors) and clocks the graphics up to 0.40 GHz.

The Intel Atom x6427FE uses the FCBGA1493 socket, supports PCI Express 3.0 and provides up to 8 PCIe lanes.

The Intel Atom x6427FE has a rated TDP of 12 W.
