Overview
SummaryThe Intel Core i3-4005U is a laptop processor with 2 cores and 4 threads, built on the Haswell architecture (22 nm process). It launched in Jul 2013. A 3-MB L3 cache backs the cores (1.8 MB per core). It addresses LPDDR3 memory up to 16 GB across 2 channels. The chip drops into the FCBGA1168 socket and exposes PCIe 2.0 (10 lanes). Rated TDP is 15 W. Notable platform capabilities: Extended Page Tables (EPT).
Performance
12 metricsThe Intel Core i3-4005U scores 895 in single-core performance and 1,646 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,214 for overall performance, 2,323 for productivity performance, 2,516 for creator performance, 1,533 for engineering performance and 3,097 for gaming performance. Its multi-core throughput works out to 823 per core, 412 per thread and 110 per watt. Its computed efficiency index is 313. Its performance index is 15, so its overall performance is 85% 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
