Intel® Core™ i5-10400H

The Intel Core i5-10400H is a laptop processor with 4 cores and 8 threads, built on the Comet Lake architecture (14 nm process). It launched in Apr 2020. Clocks run from 2.6 GHz base to 4.6 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCBGA1440 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 45 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i5-10400H scores 2,550 in single-core performance and 8,067 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,536 for overall performance, 8,814 for productivity performance, 9,027 for creator performance, 7,764 for engineering performance and 9,667 for gaming performance. Its multi-core throughput works out to 2,017 per core, 1,008 per thread and 179 per watt. Its computed efficiency index is 676. Its performance index is 56, so its overall performance is 44% 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 i5-10400H scores 26,589 in integer math, 16,857 in floating-point math, 111,673 in compression, 2,681 in cryptography, 511 in physics simulation, 7,082 in vector SIMD, 28 in the prime sieve and 14,527 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 55% below in integer math, 63% below in floating-point math, 51% below in compression, 77% below in cryptography, 53% below in physics simulation, 54% below in vector SIMD, 58% below in the prime sieve and 36% 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 i5-10400H has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 2.60 GHz and boosts up to 4.60 GHz.
