Intel® Core™ i9-8950HK

The Intel Core i9-8950HK is a laptop processor with 6 cores and 12 threads, built on the Coffee Lake architecture (14 nm process). It launched in Apr 2018. Clocks run from 2.9 GHz base to 4.8 GHz boost. A 12-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 i9-8950HK scores 2,409 in single-core performance and 10,315 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,985 for overall performance, 10,077 for productivity performance, 10,009 for creator performance, 10,251 for engineering performance and 9,806 for gaming performance. Its multi-core throughput works out to 1,719 per core, 860 per thread and 229 per watt. Its computed efficiency index is 743. 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 i9-8950HK scores 36,692 in integer math, 22,161 in floating-point math, 141,780 in compression, 3,713 in cryptography, 713 in physics simulation, 8,245 in vector SIMD, 34 in the prime sieve and 18,725 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 38% below in integer math, 52% below in floating-point math, 38% below in compression, 68% below in cryptography, 35% below in physics simulation, 47% below in vector SIMD, 49% below in the prime sieve and 17% 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 i9-8950HK has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 2.90 GHz and boosts up to 4.80 GHz.
