Intel® Core™ 3 100U

The Intel Core 3 100U is a laptop processor with a hybrid 6-core layout (2 performance cores + 4 efficiency cores) and 8 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Jan 2024. Clocks run from 1.2 GHz base to 4.7 GHz boost. A 10-MB L3 cache backs the cores (2.5 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 3 100U scores 3,461 in single-core performance and 12,302 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,525 for overall performance, 12,842 for productivity performance, 12,996 for creator performance, 12,225 for engineering performance and 13,459 for gaming performance. Its multi-core throughput works out to 2,050 per core, 1,538 per thread and 820 per watt. Its computed efficiency index is 1,685. Its performance index is 81, so its overall performance is 19% 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 3 100U scores 39,071 in integer math, 27,915 in floating-point math, 134,068 in compression, 7,981 in cryptography, 857 in physics simulation, 7,755 in vector SIMD, 51 in the prime sieve and 14,892 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 34% below in integer math, 39% below in floating-point math, 41% below in compression, 31% below in cryptography, 21% below in physics simulation, 50% below in vector SIMD, 24% below in the prime sieve and 34% 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 3 100U has 6 physical cores and runs 8 logical threads. It uses a hybrid layout of 2 performance cores and 4 efficiency cores. It runs at a base clock of 1.20 GHz and boosts up to 4.70 GHz.
