Intel® Core™ i5-12400

The Intel Core i5-12400 is a desktop processor with 6 cores and 12 threads, built on the Alder Lake architecture (Intel 7 process). It launched in Jan 2022. Clocks run from 2.5 GHz base to 4.4 GHz boost. A 18-MB L3 cache backs the cores (4.3 MB per core). It addresses DDR5, DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1700 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 65 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i5-12400 scores 3,466 in single-core performance and 18,822 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,077 for overall performance, 17,087 for productivity performance, 16,591 for creator performance, 18,704 for engineering performance and 15,104 for gaming performance. Its multi-core throughput works out to 3,137 per core, 1,569 per thread and 290 per watt. Its computed efficiency index is 1,002. Its performance index is 100, equal to the Intel Core i5-12400. 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 i5-12400 scores 58,893 in integer math, 45,899 in floating-point math, 228,054 in compression, 11,489 in cryptography, 1,090 in physics simulation, 15,509 in vector SIMD, 67 in the prime sieve and 22,652 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is equal in integer math, equal in floating-point math, equal in compression, equal in cryptography, equal in physics simulation, equal in vector SIMD, equal in the prime sieve and equal 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 i5-12400 has 6 physical cores and runs 12 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.50 GHz and boosts up to 4.40 GHz.
