Intel® Core™ i5-10400

The Intel Core i5-10400 is a desktop processor with 6 cores and 12 threads, built on the Comet Lake architecture (14 nm process). It launched in Apr 2020. Clocks run from 2.9 GHz base to 4.3 GHz boost. A 12-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 FCLGA1200 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 65 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET). Feex currently counts 1 machine in its hardware fleet with exactly this processor.

The Intel Core i5-10400 scores 2,556 in single-core performance and 11,963 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,530 for overall performance, 11,354 for productivity performance, 11,180 for creator performance, 11,888 for engineering performance and 10,659 for gaming performance. Its multi-core throughput works out to 1,994 per core, 997 per thread and 184 per watt. Its computed efficiency index is 686. Its performance index is 69, so its overall performance is 31% 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 i5-10400 scores 41,692 in integer math, 26,087 in floating-point math, 186,923 in compression, 4,031 in cryptography, 664 in physics simulation, 12,510 in vector SIMD, 33 in the prime sieve and 23,183 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 29% below in integer math, 43% below in floating-point math, 18% below in compression, 65% below in cryptography, 39% below in physics simulation, 19% below in vector SIMD, 51% below in the prime sieve and 2% above 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 i5-10400 has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 2.90 GHz and boosts up to 4.30 GHz.
