Intel® Pentium® 4405Y

The Intel Pentium 4405Y is a laptop processor with 2 cores and 4 threads, built on the Skylake architecture. It launched in Jul 2015. A 2-MB L3 cache backs the cores (1.4 MB per core). It addresses LPDDR3 memory up to 16 GB across 2 channels. The chip drops into the FCBGA1515 socket and exposes PCIe 3.0 (10 lanes). Rated TDP is 6 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Pentium 4405Y scores 792 in single-core performance and 1,427 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,063 for overall performance, 2,036 for productivity performance, 2,210 for creator performance, 1,329 for engineering performance and 2,733 for gaming performance. Its multi-core throughput works out to 714 per core, 357 per thread and 238 per watt. Its computed efficiency index is 434. 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 Pentium 4405Y scores 4,689 in integer math, 3,001 in floating-point math, 20,275 in compression, 526 in cryptography, 159 in physics simulation, 623 in vector SIMD, 7 in the prime sieve and 2,698 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 92% below in integer math, 93% below in floating-point math, 91% below in compression, 95% below in cryptography, 85% below in physics simulation, 96% below in vector SIMD, 90% 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 Pentium 4405Y 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.
