Intel® Atom™ E3815

The Intel Atom E3815 is a embedded processor with 1 cores and 1 threads, built on the Bay Trail architecture. It launched in Oct 2013. A 512-MB L3 cache backs the cores (513.4 MB per core). It addresses DDR3L memory up to 8 GB across 1 channels. The chip drops into the FCBGA1170 socket and exposes PCIe 2.0 (4 lanes). Rated TDP is 5 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom E3815 scores 273 in single-core performance and 193 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 230 for overall performance, 508 for productivity performance, 598 for creator performance, 177 for engineering performance and 867 for gaming performance. Its multi-core throughput works out to 193 per core, 193 per thread and 39 per watt. Its computed efficiency index is 103. Its performance index is 3, so its overall performance is 97% 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 E3815 scores 1,070 in integer math, 251 in floating-point math, 4,254 in compression, 89 in cryptography, 28 in physics simulation, 63 in vector SIMD, 1 in the prime sieve and 563 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 98% below in integer math, 99% below in floating-point math, 98% below in compression, 99% below in cryptography, 97% below in physics simulation, 100% below in vector SIMD, 99% below in the prime sieve and 98% 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 E3815 has 1 physical core and runs 1 logical thread. 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 E3815 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 E3815 has 448 KB of L1 cache, 1 MB of L2 cache and 512 MB of L3 cache. That adds up to about 513.4 MB of cache, or 513.44 MB per core.

The Intel Atom E3815 has a 3-level cache hierarchy: L1 at 448 KB, L2 at 1 MB and L3 at 512 MB. L3 is the largest level and makes up about 100% of the cache listed here.

The Intel Atom E3815 supports DDR3L memory, addresses up to 8 GB of memory, uses 1 memory channel and runs memory at up to 1,066 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Atom E3815 includes integrated graphics (Intel HD Graphics for Intel Atom Processor Z3700 Series) and clocks the graphics up to 0.40 GHz.

The Intel Atom E3815 uses the FCBGA1170 socket, supports PCI Express 2.0 and provides up to 4 PCIe lanes.

The Intel Atom E3815 has a rated TDP of 5 W.
