Intel® Core™ i3-4020Y

The Intel Core i3-4020Y 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 (2.1 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 (12 lanes). Rated TDP is 12 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i3-4020Y scores 788 in single-core performance and 1,462 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,073 for overall performance, 2,054 for productivity performance, 2,223 for creator performance, 1,361 for engineering performance and 2,730 for gaming performance. Its multi-core throughput works out to 731 per core, 366 per thread and 127 per watt. Its computed efficiency index is 317. Its performance index is 13, so its overall performance is 87% 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 Core i3-4020Y scores 4,921 in integer math, 2,476 in floating-point math, 20,666 in compression, 386 in cryptography, 159 in physics simulation, 1,326 in vector SIMD, 9 in the prime sieve and 2,793 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 92% below in integer math, 95% below in floating-point math, 91% below in compression, 97% below in cryptography, 85% below in physics simulation, 91% below in vector SIMD, 87% 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.

The Intel Core i3-4020Y has 2 physical cores and runs 4 logical threads. It runs 2 threads per core. It runs at a base clock of 1.50 GHz.
