Intel® Core™ i7-8086K

The Intel Core i7-8086K is a desktop processor with 6 cores and 12 threads, built on the Coffee Lake architecture (14 nm process). It launched in Apr 2018. Clocks run from 4.0 GHz base to 5.0 GHz boost. A 12-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1151-2 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 95 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i7-8086K scores 2,822 in single-core performance and 14,083 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,304 for overall performance, 13,105 for productivity performance, 12,825 for creator performance, 13,995 for engineering performance and 11,987 for gaming performance. Its multi-core throughput works out to 2,347 per core, 1,174 per thread and 148 per watt. Its computed efficiency index is 647. Its performance index is 78, so its overall performance is 22% 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 i7-8086K scores 47,474 in integer math, 29,491 in floating-point math, 205,758 in compression, 4,951 in cryptography, 857 in physics simulation, 13,967 in vector SIMD, 41 in the prime sieve and 26,129 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 19% below in integer math, 36% below in floating-point math, 10% below in compression, 57% below in cryptography, 21% below in physics simulation, 10% below in vector SIMD, 39% below in the prime sieve and 15% above 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 i7-8086K has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 4.00 GHz and boosts up to 5.00 GHz.
