Intel® Core™ i3-1305U

The Intel Core i3-1305U is a laptop processor with a hybrid 5-core layout (1 performance cores + 4 efficiency cores) and 6 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Jan 2023. Clocks run from 1.6 GHz base to 4.5 GHz boost. A 10-MB L3 cache backs the cores (2.7 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: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i3-1305U scores 2,932 in single-core performance and 8,422 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,969 for overall performance, 9,579 for productivity performance, 9,910 for creator performance, 8,238 for engineering performance and 10,902 for gaming performance. Its multi-core throughput works out to 1,684 per core, 1,404 per thread and 562 per watt. Its computed efficiency index is 1,283. Its performance index is 62, so its overall performance is 38% 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 i3-1305U scores 26,390 in integer math, 18,611 in floating-point math, 90,041 in compression, 5,672 in cryptography, 513 in physics simulation, 5,100 in vector SIMD, 35 in the prime sieve and 10,571 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 55% below in integer math, 59% below in floating-point math, 61% below in compression, 51% below in cryptography, 53% below in physics simulation, 67% below in vector SIMD, 48% below in the prime sieve and 53% 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 i3-1305U has 5 physical cores and runs 6 logical threads. It uses a hybrid layout of 1 performance cores and 4 efficiency cores. It runs at a base clock of 1.60 GHz and boosts up to 4.50 GHz.
