Intel® Core™ Ultra 3 105UL

The Intel Core Ultra 3 105UL is a embedded processor with a hybrid 8-core layout (2 performance cores + 4 efficiency cores) and 10 threads, built on the Meteor Lake architecture (Intel 4 process). It launched in Apr 2024. Clocks run from 1.5 GHz base to 4.2 GHz boost. A 10-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR5 memory up to 96 GB across 2 channels. The chip drops into the FCLGA1851 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 Ultra 3 105UL scores 3,382 in single-core performance and 10,285 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,898 for overall performance, 11,420 for productivity performance, 11,744 for creator performance, 10,542 for engineering performance and 12,717 for gaming performance. Its multi-core throughput works out to 1,286 per core, 1,029 per thread and 686 per watt. Its computed efficiency index is 1,523. Its performance index is 73, so its overall performance is 27% 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 Ultra 3 105UL scores 41,171 in integer math, 30,750 in floating-point math, 93,961 in compression, 6,354 in cryptography, 718 in physics simulation, 5,634 in vector SIMD, 44 in the prime sieve and 11,179 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 30% below in integer math, 33% below in floating-point math, 59% below in compression, 45% below in cryptography, 34% below in physics simulation, 64% below in vector SIMD, 34% below in the prime sieve and 51% 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 Ultra 3 105UL has 8 physical cores and runs 10 logical threads. It uses a hybrid layout of 2 performance cores and 4 efficiency cores. It runs at a base clock of 1.50 GHz and boosts up to 4.20 GHz.
