Intel® Core™ i5-8265U

The Intel Core i5-8265U is a laptop processor with 4 cores and 8 threads, built on the Whiskey Lake architecture (14 nm process). It launched in Jul 2018. Clocks run from 1.6 GHz base to 3.9 GHz boost. A 6-MB L3 cache backs the cores (1.8 MB per core). It addresses DDR4, LPDDR3 memory up to 64 GB across 2 channels. The chip drops into the FCBGA1528 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 15 W. Notable platform capabilities: Extended Page Tables (EPT). Feex currently counts 1 machine in its hardware fleet with exactly this processor.

The Intel Core i5-8265U scores 2,003 in single-core performance and 5,767 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,399 for overall performance, 6,553 for productivity performance, 6,777 for creator performance, 5,551 for engineering performance and 7,451 for gaming performance. Its multi-core throughput works out to 1,442 per core, 721 per thread and 385 per watt. Its computed efficiency index is 878. Its performance index is 42, so its overall performance is 58% 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 i5-8265U scores 21,349 in integer math, 12,782 in floating-point math, 74,639 in compression, 1,940 in cryptography, 401 in physics simulation, 4,870 in vector SIMD, 18 in the prime sieve and 9,995 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 64% below in integer math, 72% below in floating-point math, 67% below in compression, 83% below in cryptography, 63% below in physics simulation, 69% below in vector SIMD, 73% below in the prime sieve and 56% 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 i5-8265U has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 1.60 GHz and boosts up to 3.90 GHz.
