Intel® Core™ 5 120U

The Intel Core 5 120U is a laptop processor with a hybrid 10-core layout (2 performance cores + 8 efficiency cores) and 12 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Jan 2024. Clocks run from 1.4 GHz base to 5.0 GHz boost. A 12-MB L3 cache backs the cores (1.9 MB per core). It addresses DDR5, DDR4, LPDDR5, LPDDR4X memory up to 96 GB across 2 channels. The chip drops into the FCBGA1744 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 15 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core 5 120U scores 3,455 in single-core performance and 14,861 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,166 for overall performance, 14,497 for productivity performance, 14,393 for creator performance, 15,697 for engineering performance and 14,080 for gaming performance. Its multi-core throughput works out to 1,486 per core, 1,238 per thread and 991 per watt. Its computed efficiency index is 1,850. 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 5 120U scores 51,795 in integer math, 35,580 in floating-point math, 164,307 in compression, 10,329 in cryptography, 924 in physics simulation, 9,189 in vector SIMD, 52 in the prime sieve and 18,799 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 12% below in integer math, 22% below in floating-point math, 28% below in compression, 10% below in cryptography, 15% below in physics simulation, 41% below in vector SIMD, 22% below in the prime sieve and 17% 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.

The Intel Core 5 120U has 10 physical cores and runs 12 logical threads. It uses a hybrid layout of 2 performance cores and 8 efficiency cores. It runs at a base clock of 1.40 GHz and boosts up to 5.00 GHz.
