Intel® Core™ i5-14450HX

The Intel Core i5-14450HX is a laptop processor with a hybrid 10-core layout (6 performance cores + 4 efficiency cores) and 16 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Jan 2024. Clocks run from 2.4 GHz base to 4.8 GHz boost. A 20-MB L3 cache backs the cores (3.7 MB per core). It addresses DDR5, DDR4 memory up to 192 GB across 2 channels. The chip drops into the FCBGA1964 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 55 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i5-14450HX scores 3,656 in single-core performance and 23,707 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,310 for overall performance, 20,528 for productivity performance, 19,620 for creator performance, 25,041 for engineering performance and 16,895 for gaming performance. Its multi-core throughput works out to 2,371 per core, 1,482 per thread and 431 per watt. Its computed efficiency index is 1,255. Its performance index is 115, so its overall performance is 15% above 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 i5-14450HX scores 78,897 in integer math, 58,448 in floating-point math, 280,449 in compression, 15,695 in cryptography, 1,477 in physics simulation, 17,332 in vector SIMD, 98 in the prime sieve and 29,855 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 34% above in integer math, 27% above in floating-point math, 23% above in compression, 37% above in cryptography, 36% above in physics simulation, 12% above in vector SIMD, 46% above in the prime sieve and 32% 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.
