Intel® Core™ i3-1125G4

The Intel Core i3-1125G4 is a laptop processor with 4 cores and 8 threads, built on the Tiger Lake architecture (10 nm process). It launched in Jan 2021. Clocks run from 2.0 GHz base to 3.7 GHz boost. A 8-MB L3 cache backs the cores (3.3 MB per core). It addresses DDR4, LPDDR4X memory up to 64 GB across 2 channels. The chip drops into the FCBGA1449 socket and exposes PCIe 4.0 (16 lanes). Rated TDP is 28 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i3-1125G4 scores 2,413 in single-core performance and 9,223 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,718 for overall performance, 9,373 for productivity performance, 9,416 for creator performance, 8,877 for engineering performance and 9,545 for gaming performance. Its multi-core throughput works out to 2,306 per core, 1,153 per thread and 329 per watt. Its computed efficiency index is 892. Its performance index is 58, so its overall performance is 42% 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 i3-1125G4 scores 29,002 in integer math, 17,816 in floating-point math, 103,429 in compression, 5,422 in cryptography, 544 in physics simulation, 7,578 in vector SIMD, 33 in the prime sieve and 12,449 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 51% below in integer math, 61% below in floating-point math, 55% below in compression, 53% below in cryptography, 50% below in physics simulation, 51% below in vector SIMD, 51% below in the prime sieve and 45% 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 i3-1125G4 has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.70 GHz.

After an audit, 2 values were corrected and 1 empty field was filled on the Intel Core i3-1125G4 record. Each change is listed with its old value, new value, rule and sources.

• Base clock: 900 MHz → 2,000 MHz. Rule: Base clock was the configurable-TDP-down figure. stored 900 MHz is the cTDP-down end of the Wikipedia base range 900-2000 MHz; PassMark base 2000 MHz = the nominal (high-TDP) base.
