Intel® Core™ i5-8305G

The Intel Core i5-8305G is a laptop processor with 4 cores and 8 threads, built on the Kaby Lake architecture (14 nm process). It launched in Jul 2018. Clocks run from 2.8 GHz base to 3.8 GHz boost. A 6-MB L3 cache backs the cores (1.8 MB per core). It addresses DDR4 memory up to 64 GB across 2 channels. The chip drops into the FCBGA2270 socket and exposes PCIe 3.0 (8 lanes). Rated TDP is 65 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i5-8305G scores 1,981 in single-core performance and 6,752 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,657 for overall performance, 7,162 for productivity performance, 7,279 for creator performance, 6,499 for engineering performance and 7,631 for gaming performance. Its multi-core throughput works out to 1,688 per core, 844 per thread and 104 per watt. Its computed efficiency index is 454. Its performance index is 45, so its overall performance is 55% 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 i5-8305G scores 22,728 in integer math, 13,984 in floating-point math, 94,058 in compression, 2,308 in cryptography, 419 in physics simulation, 6,430 in vector SIMD, 18 in the prime sieve and 12,467 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 61% below in integer math, 70% below in floating-point math, 59% below in compression, 80% below in cryptography, 62% below in physics simulation, 59% below in vector SIMD, 73% 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 i5-8305G has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 2.80 GHz and boosts up to 3.80 GHz.
