Intel® Core™ i9-13900KS

The Intel Core i9-13900KS is a desktop processor with a hybrid 24-core layout (8 performance cores + 16 efficiency cores) and 32 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Jan 2023. Clocks run from 3.2 GHz base to 6.0 GHz boost. A 36-MB L3 cache backs the cores (2.9 MB per core). It addresses DDR5, DDR4 memory up to 192 GB across 2 channels. The chip drops into the FCLGA1700 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 150 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i9-13900KS scores 4,716 in single-core performance and 60,498 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 16,891 for overall performance, 45,926 for productivity performance, 41,763 for creator performance, 77,135 for engineering performance and 29,273 for gaming performance. Its multi-core throughput works out to 2,521 per core, 1,891 per thread and 403 per watt. Its computed efficiency index is 1,379. Its performance index is 209, so its overall performance is 109% 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 i9-13900KS scores 210,715 in integer math, 154,416 in floating-point math, 810,875 in compression, 47,589 in cryptography, 3,432 in physics simulation, 47,960 in vector SIMD, 256 in the prime sieve and 89,943 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 258% above in integer math, 236% above in floating-point math, 256% above in compression, 314% above in cryptography, 215% above in physics simulation, 209% above in vector SIMD, 282% above in the prime sieve and 297% 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.
