Overview
SummaryThe Intel Atom Z3740D is a laptop processor with 4 cores and 4 threads, built on the Bay Trail architecture. It launched in Jul 2013. Clocks run from 1.33 GHz base to 1.9 GHz boost. A 2-MB L3 cache backs the cores (1.1 MB per core). It addresses DDR3L memory up to 2 GB across 1 channels. It uses the UTFCBGA1380 socket. Notable platform capabilities: VT-x (Hardware Virtualization).
Performance
10 metricsThe Intel Atom Z3740D scores 434 in single-core performance and 618 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 518 for overall performance, 1,009 for productivity performance, 1,121 for creator performance, 595 for engineering performance and 1,457 for gaming performance. Its multi-core throughput works out to 155 per core and 155 per thread. Its performance index is 6, so its overall performance is 94% 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 Z3740D scores 875 in integer math, 1,265 in floating-point math, 18,750 in compression, 400 in cryptography, 121 in physics simulation, 239 in vector SIMD, 2 in the prime sieve and 2,706 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 99% below in integer math, 97% below in floating-point math, 92% below in compression, 97% below in cryptography, 89% below in physics simulation, 98% below in vector SIMD, 97% below in the prime sieve and 88% 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.
