Intel® Core™ i5-11400H

The Intel Core i5-11400H is a laptop processor with 6 cores and 12 threads, built on the Tiger Lake architecture (10 nm process). It launched in Apr 2021. Clocks run from 2.7 GHz base to 4.5 GHz boost. A 12-MB L3 cache backs the cores (3.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCBGA1787 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 35 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i5-11400H scores 2,945 in single-core performance and 15,103 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,669 for overall performance, 13,940 for productivity performance, 13,608 for creator performance, 15,009 for engineering performance and 12,611 for gaming performance. Its multi-core throughput works out to 2,517 per core, 1,259 per thread and 432 per watt. Its computed efficiency index is 1,127. Its performance index is 83, so its overall performance is 17% 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 i5-11400H scores 52,672 in integer math, 31,677 in floating-point math, 186,607 in compression, 9,117 in cryptography, 672 in physics simulation, 12,639 in vector SIMD, 47 in the prime sieve and 22,299 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 11% below in integer math, 31% below in floating-point math, 18% below in compression, 21% below in cryptography, 38% below in physics simulation, 19% below in vector SIMD, 30% below in the prime sieve and 2% 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 i5-11400H has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 4.50 GHz.

After an audit, 2 values were corrected and 1 empty field was filled on the Intel Core i5-11400H record. Each change is listed with its old value, new value, rule and sources.

• Base clock: 2,200 MHz → 2,700 MHz. Rule: Base clock was the configurable-TDP-down figure. stored 2200 MHz is the cTDP-down end of the Wikipedia base range 2200-2700 MHz; PassMark base 2700 MHz = the nominal (high-TDP) base.
