Intel® Core™ i3-1005G1

The Intel Core i3-1005G1 is a laptop processor with 2 cores and 4 threads, built on the Ice Lake architecture (10 nm process). It launched in Jul 2019. Clocks run from 1.2 GHz base to 3.4 GHz boost. A 4-MB L3 cache backs the cores (2.6 MB per core). It addresses DDR4, LPDDR4 memory up to 64 GB across 2 channels. The chip drops into the FCBGA1526 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 15 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT).

The Intel Core i3-1005G1 scores 2,126 in single-core performance and 4,775 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,186 for overall performance, 6,080 for productivity performance, 6,453 for creator performance, 4,447 for engineering performance and 7,572 for gaming performance. Its multi-core throughput works out to 2,388 per core, 1,194 per thread and 318 per watt. Its computed efficiency index is 823. Its performance index is 39, so its overall performance is 61% 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 i3-1005G1 scores 14,509 in integer math, 8,835 in floating-point math, 52,329 in compression, 2,719 in cryptography, 331 in physics simulation, 3,786 in vector SIMD, 15 in the prime sieve and 6,394 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 75% below in integer math, 81% below in floating-point math, 77% below in compression, 76% below in cryptography, 70% below in physics simulation, 76% below in vector SIMD, 78% below in the prime sieve and 72% 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 i3-1005G1 has 2 physical cores and runs 4 logical threads. It runs 2 threads per core. It runs at a base clock of 1.20 GHz and boosts up to 3.40 GHz.
