Intel® Core™ i5-12450H

The Intel Core i5-12450H is a laptop processor with a hybrid 8-core layout (4 performance cores + 4 efficiency cores) and 12 threads, built on the Alder Lake architecture (Intel 7 process). It launched in Jan 2022. Clocks run from 2.0 GHz base to 4.4 GHz boost. A 12-MB L3 cache backs the cores (2.5 MB per core). It addresses DDR5, DDR4, LPDDR5, LPDDR4X memory up to 64 GB across 2 channels. The chip drops into the FCBGA1744 socket and exposes PCIe 4.0 (28 lanes). Rated TDP is 45 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i5-12450H scores 3,269 in single-core performance and 15,859 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,200 for overall performance, 14,885 for productivity performance, 14,607 for creator performance, 16,255 for engineering performance and 13,772 for gaming performance. Its multi-core throughput works out to 1,982 per core, 1,322 per thread and 352 per watt. Its computed efficiency index is 1,073. Its performance index is 89, so its overall performance is 11% 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 i5-12450H scores 53,975 in integer math, 39,885 in floating-point math, 190,003 in compression, 10,552 in cryptography, 852 in physics simulation, 11,661 in vector SIMD, 44 in the prime sieve and 20,487 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 8% below in integer math, 13% below in floating-point math, 17% below in compression, 8% below in cryptography, 22% below in physics simulation, 25% below in vector SIMD, 34% below in the prime sieve and 10% 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.
