Intel® Atom™ C3758R

The Intel Atom C3758R is a server processor with 8 cores and 8 threads, built on the Denverton architecture. It launched in Apr 2020. A 16-MB L3 cache backs the cores (2.0 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 (20 lanes). Rated TDP is 26 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom C3758R scores 955 in single-core performance and 5,086 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,204 for overall performance, 4,643 for productivity performance, 4,516 for creator performance, 5,213 for engineering performance and 4,137 for gaming performance. Its multi-core throughput works out to 636 per core, 636 per thread and 196 per watt. Its computed efficiency index is 432. Its performance index is 27, so its overall performance is 73% 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 C3758R scores 25,408 in integer math, 6,912 in floating-point math, 85,226 in compression, 3,789 in cryptography, 348 in physics simulation, 1,818 in vector SIMD, 21 in the prime sieve and 11,635 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 57% below in integer math, 85% below in floating-point math, 63% below in compression, 67% below in cryptography, 68% below in physics simulation, 88% below in vector SIMD, 69% below in the prime sieve and 49% 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 C3758R 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 2.40 GHz.

The Intel Atom C3758R 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 Apr 2020.

The Intel Atom C3758R has 16 MB of L3 cache. That adds up to about 16.0 MB of cache, or 2.00 MB per core. Feex has no recorded L1 cache size for this processor.
