Intel® Atom™ C5315

The Intel Atom C5315 is a server processor with 4 cores and 4 threads, built on the Parker Ridge architecture. It launched in Apr 2022. A 9-MB L3 cache backs the cores (4.6 MB per core). It addresses DDR4 memory up to 256 GB across 2 channels. The chip drops into the FCBGA2106 socket and exposes PCIe 3.0 (12 lanes). Rated TDP is 38 W. Notable platform capabilities: VT-x (Hardware Virtualization).

The Intel Atom C5315 scores 1,284 in single-core performance and 2,980 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,956 for overall performance, 3,735 for productivity performance, 3,950 for creator performance, 2,868 for engineering performance and 4,597 for gaming performance. Its multi-core throughput works out to 745 per core, 745 per thread and 78 per watt. Its computed efficiency index is 317. Its performance index is 24, so its overall performance is 76% 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 C5315 scores 11,241 in integer math, 7,377 in floating-point math, 24,636 in compression, 2,804 in cryptography, 207 in physics simulation, 1,366 in vector SIMD, 33 in the prime sieve and 3,107 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 81% below in integer math, 84% below in floating-point math, 89% below in compression, 76% below in cryptography, 81% below in physics simulation, 91% below in vector SIMD, 51% below in the prime sieve and 86% 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 C5315 has 4 physical cores and runs 4 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 C5315 is a server processor, belongs to the Intel Atom C family, uses the Parker Ridge architecture, carries the codename Parker Ridge and is manufactured on a 10 nm process. It launched in Apr 2022.

The Intel Atom C5315 has 256 KB of L1 cache, 9 MB of L2 cache and 9 MB of L3 cache. That adds up to about 18.3 MB of cache, or 4.56 MB per core.

The Intel Atom C5315 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 9 MB and L3 at 9 MB. L2 is the largest level and makes up about 49% of the cache listed here.

The Intel Atom C5315 supports DDR4 memory, addresses up to 256 GB of memory, uses 2 memory channels, runs memory at up to 2,400 MT/s and delivers up to 38.4 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Atom C5315 uses the FCBGA2106 socket, supports PCI Express 3.0 and provides up to 12 PCIe lanes.

The Intel Atom C5315 has a rated TDP of 38 W.
