Overview
SummaryThe Intel Atom C3808 is a server processor with 12 cores and 12 threads, built on the Denverton architecture. It launched in Jul 2017. Clocks run from 2.0 GHz base to 2.0 GHz boost. A 12-MB L3 cache backs the cores (1.0 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 (16 lanes). Rated TDP is 25 W. Notable platform capabilities: Extended Page Tables (EPT).
Performance
12 metricsThe Intel Atom C3808 scores 801 in single-core performance and 5,671 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,131 for overall performance, 4,808 for productivity performance, 4,561 for creator performance, 6,167 for engineering performance and 3,821 for gaming performance. Its multi-core throughput works out to 473 per core, 473 per thread and 227 per watt. Its computed efficiency index is 426. Its performance index is 26, so its overall performance is 74% 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.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores 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 C3808 scores 32,298 in integer math, 8,798 in floating-point math, 105,882 in compression, 4,674 in cryptography, 293 in physics simulation, 2,341 in vector SIMD, 12 in the prime sieve and 13,679 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 45% below in integer math, 81% below in floating-point math, 54% below in compression, 59% below in cryptography, 73% below in physics simulation, 85% below in vector SIMD, 82% below in the prime sieve and 40% 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.
