Intel® Core™ Ultra 5 125H

The Intel Core Ultra 5 125H is a mobile processor with a hybrid 14-core layout (4 performance cores + 8 efficiency cores) and 18 threads, built on the Meteor Lake architecture (Intel 4 process). It launched in Oct 2023. Clocks run from 1.2 GHz base to 4.5 GHz boost. A 18-MB L3 cache backs the cores (1.5 MB per core). It addresses LPDDR5, DDR5 memory up to 96 GB across 2 channels. The chip drops into the FCBGA2049 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 28 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 5 125H scores 3,337 in single-core performance and 20,341 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,239 for overall performance, 17,893 for productivity performance, 17,194 for creator performance, 22,756 for engineering performance and 15,096 for gaming performance. Its multi-core throughput works out to 1,453 per core, 1,130 per thread and 727 per watt. Its computed efficiency index is 1,557. Its performance index is 102, so its overall performance is 2% 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 Ultra 5 125H scores 67,828 in integer math, 49,607 in floating-point math, 223,577 in compression, 13,578 in cryptography, 1,366 in physics simulation, 13,007 in vector SIMD, 86 in the prime sieve and 26,017 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 15% above in integer math, 8% above in floating-point math, 2% below in compression, 18% above in cryptography, 25% above in physics simulation, 16% below in vector SIMD, 28% above in the prime sieve and 15% 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 Ultra 5 125H has 14 physical cores and runs 18 logical threads. It uses a hybrid layout of 4 performance cores and 8 efficiency cores. It runs at a base clock of 1.20 GHz and boosts up to 4.50 GHz.
