Intel® Atom™ C3758

The Intel Atom C3758 is a server processor with 8 cores and 8 threads, built on the Denverton architecture. It launched in Jul 2017. Clocks run from 2.2 GHz base to 2.2 GHz boost. A 16-MB L3 cache backs the cores (3.1 MB per core). It addresses DDR4 memory up to 256 GB across 2 channels. The chip drops into the FCBGA1310 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 25 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom C3758 scores 871 in single-core performance and 4,787 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,042 for overall performance, 4,331 for productivity performance, 4,201 for creator performance, 4,907 for engineering performance and 3,810 for gaming performance. Its multi-core throughput works out to 598 per core, 598 per thread and 192 per watt. Its computed efficiency index is 408. Its performance index is 25, so its overall performance is 75% 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 C3758 scores 23,158 in integer math, 6,416 in floating-point math, 76,470 in compression, 3,363 in cryptography, 432 in physics simulation, 1,718 in vector SIMD, 22 in the prime sieve and 10,917 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 61% below in integer math, 86% below in floating-point math, 66% below in compression, 71% below in cryptography, 60% below in physics simulation, 89% below in vector SIMD, 67% below in the prime sieve and 52% 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 C3758 has 8 physical cores and runs 8 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.20 GHz and boosts up to 2.20 GHz.

The Intel Atom C3758 is a server processor, belongs to the Intel Atom C family, uses the Denverton architecture, carries the codename Denverton and is manufactured on a 14 nm process. It launched in Jul 2017.

The Intel Atom C3758 has 896 KB of L1 cache, 8 MB of L2 cache and 16 MB of L3 cache. That adds up to about 24.9 MB of cache, or 3.11 MB per core.

The Intel Atom C3758 has a 3-level cache hierarchy: L1 at 896 KB, L2 at 8 MB and L3 at 16 MB. L3 is the largest level and makes up about 64% of the cache listed here.

The Intel Atom C3758 supports DDR4 memory, addresses up to 256 GB of memory, uses 2 memory channels and runs memory at up to 2,400 MT/s. It does not support DDR5 and LPDDR memory.
