Intel® Core™ i7-6820HK

The Intel Core i7-6820HK is a laptop processor with 4 cores and 8 threads, built on the Skylake architecture (14 nm process). It launched in Jul 2015. Clocks run from 2.7 GHz base to 3.6 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4, LPDDR3 memory up to 64 GB across 2 channels. The chip drops into the FCBGA1440 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 45 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i7-6820HK scores 1,979 in single-core performance and 7,005 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,723 for overall performance, 7,324 for productivity performance, 7,415 for creator performance, 6,742 for engineering performance and 7,688 for gaming performance. Its multi-core throughput works out to 1,751 per core, 876 per thread and 156 per watt. Its computed efficiency index is 555. Its performance index is 46, so its overall performance is 54% 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 i7-6820HK scores 21,696 in integer math, 13,552 in floating-point math, 94,992 in compression, 2,334 in cryptography, 580 in physics simulation, 6,245 in vector SIMD, 28 in the prime sieve and 12,244 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 63% below in integer math, 70% below in floating-point math, 58% below in compression, 80% below in cryptography, 47% below in physics simulation, 60% below in vector SIMD, 58% below in the prime sieve and 46% 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 i7-6820HK has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 3.60 GHz.
