Intel® Atom™ C2758

The Intel Atom C2758 is a embedded processor with 8 cores and 8 threads, built on the Rangeley architecture. It launched in Jul 2013. A 4-MB L3 cache backs the cores (1.1 MB per core). It addresses DDR3 memory up to 64 GB across 2 channels. The chip drops into the FCBGA1283 socket and exposes PCIe 2.0 (16 lanes). Rated TDP is 20 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom C2758 scores 571 in single-core performance and 2,317 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,150 for overall performance, 2,305 for productivity performance, 2,302 for creator performance, 2,375 for engineering performance and 2,292 for gaming performance. Its multi-core throughput works out to 290 per core, 290 per thread and 116 per watt. Its computed efficiency index is 257. Its performance index is 14, so its overall performance is 86% 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 C2758 scores 12,684 in integer math, 2,974 in floating-point math, 55,702 in compression, 1,018 in cryptography, 228 in physics simulation, 843 in vector SIMD, 9 in the prime sieve and 6,826 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 78% below in integer math, 94% below in floating-point math, 76% below in compression, 91% below in cryptography, 79% below in physics simulation, 95% below in vector SIMD, 87% below in the prime sieve and 70% 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 C2758 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 C2758 is a embedded processor, belongs to the Intel Atom C family, uses the Rangeley architecture, carries the codename Rangeley and is manufactured on a 22 nm process. It launched in Jul 2013.

The Intel Atom C2758 has 448 KB of L1 cache, 4 MB of L2 cache and 4 MB of L3 cache. That adds up to about 8.4 MB of cache, or 1.05 MB per core.

The Intel Atom C2758 has a 3-level cache hierarchy: L1 at 448 KB, L2 at 4 MB and L3 at 4 MB. L2 is the largest level and makes up about 47% of the cache listed here.
