Overview
SummaryThe Intel Atom x7405C is a embedded processor with 4 cores and 4 threads, built on the Amston Lake architecture. It launched in Apr 2024. Boost clock reaches 3.4 GHz. A 6-MB L3 cache backs the cores (1.5 MB per core). It addresses DDR4, DDR5, LPDDR5 memory up to 32 GB across 1 channels. It uses the FCBGA1264 socket. Rated TDP is 12 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT).
Performance
12 metricsThe Intel Atom x7405C scores 1,675 in single-core performance and 5,218 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,956 for overall performance, 5,737 for productivity performance, 5,885 for creator performance, 5,022 for engineering performance and 6,330 for gaming performance. Its multi-core throughput works out to 1,305 per core, 1,305 per thread and 435 per watt. Its computed efficiency index is 853. Its performance index is 37, so its overall performance is 63% 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 x7405C scores 14,669 in integer math, 9,063 in floating-point math, 56,317 in compression, 4,004 in cryptography, 460 in physics simulation, 2,771 in vector SIMD, 22 in the prime sieve and 8,089 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 75% below in integer math, 80% below in floating-point math, 75% below in compression, 65% below in cryptography, 58% below in physics simulation, 82% below in vector SIMD, 67% below in the prime sieve and 64% 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.
