Intel® Atom™ E3826

The Intel Atom E3826 is a embedded processor with 2 cores and 2 threads, built on the Bay Trail architecture. It launched in Oct 2013. A 1-MB L3 cache backs the cores (1.1 MB per core). It addresses DDR3L memory up to 8 GB across 2 channels. The chip drops into the FCBGA1170 socket and exposes PCIe 2.0 (4 lanes). Rated TDP is 7 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom E3826 scores 397 in single-core performance and 334 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 364 for overall performance, 773 for productivity performance, 898 for creator performance, 311 for engineering performance and 1,275 for gaming performance. Its multi-core throughput works out to 167 per core, 167 per thread and 48 per watt. Its computed efficiency index is 138. Its performance index is 5, so its overall performance is 95% 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 E3826 scores 1,936 in integer math, 435 in floating-point math, 8,216 in compression, 122 in cryptography, 54 in physics simulation, 126 in vector SIMD, 2 in the prime sieve and 1,179 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 97% below in integer math, 99% below in floating-point math, 96% below in compression, 99% below in cryptography, 95% below in physics simulation, 99% below in vector SIMD, 97% below in the prime sieve and 95% 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 E3826 has 2 physical cores and runs 2 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.46 GHz.

The Intel Atom E3826 is a embedded processor, belongs to the Intel Atom E family, uses the Bay Trail architecture, carries the codename Bay Trail and is manufactured on a 22 nm process. It launched in Oct 2013.

The Intel Atom E3826 has 112 KB of L1 cache, 1 MB of L2 cache and 1 MB of L3 cache. That adds up to about 2.1 MB of cache, or 1.05 MB per core. Each core has 512 KB of private L2 cache.

The Intel Atom E3826 has a 3-level cache hierarchy: L1 at 112 KB, L2 at 1 MB and L3 at 1 MB. L2 is the largest level and makes up about 47% of the cache listed here.

The Intel Atom E3826 supports DDR3L memory, addresses up to 8 GB of memory, uses 2 memory channels and runs memory at up to 1,066 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Atom E3826 includes integrated graphics (Intel HD Graphics for Intel Atom Processor Z3700 Series) and clocks the graphics up to 0.67 GHz.

The Intel Atom E3826 uses the FCBGA1170 socket, supports PCI Express 2.0 and provides up to 4 PCIe lanes.

The Intel Atom E3826 has a rated TDP of 7 W.
