Intel® Core™ i9-10850K

The Intel Core i9-10850K is a desktop processor with 10 cores and 20 threads, built on the Comet Lake architecture (14 nm process). It launched in Jul 2020. Clocks run from 3.6 GHz base to 5.2 GHz boost. A 20-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 FCLGA1200 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 125 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i9-10850K scores 3,066 in single-core performance and 21,861 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,187 for overall performance, 18,502 for productivity performance, 17,542 for creator performance, 23,091 for engineering performance and 14,663 for gaming performance. Its multi-core throughput works out to 2,186 per core, 1,093 per thread and 175 per watt. Its computed efficiency index is 732. Its performance index is 101, so its overall performance is 1% above 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 i9-10850K scores 84,460 in integer math, 52,483 in floating-point math, 370,791 in compression, 7,368 in cryptography, 990 in physics simulation, 24,554 in vector SIMD, 60 in the prime sieve and 45,654 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 43% above in integer math, 14% above in floating-point math, 63% above in compression, 36% below in cryptography, 9% below in physics simulation, 58% above in vector SIMD, 10% below in the prime sieve and 102% 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 i9-10850K has 10 physical cores and runs 20 logical threads. It runs 2 threads per core. It runs at a base clock of 3.60 GHz and boosts up to 5.20 GHz.
