Intel® Core™ i7-13645HX

The Intel Core i7-13645HX is a laptop processor with a hybrid 14-core layout (6 performance cores + 8 efficiency cores) and 20 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Mar 2026. Clocks run from 2.6 GHz base to 4.9 GHz boost. A 24-MB L3 cache backs the cores (3.2 MB per core). It supports DDR4, DDR5 memory. The chip drops into the FCBGA1964 socket and exposes PCIe 5.0 (16 lanes). Rated TDP is 55 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i7-13645HX scores 3,567 in single-core performance and 29,399 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,240 for overall performance, 24,103 for productivity performance, 22,590 for creator performance, 32,890 for engineering performance and 18,051 for gaming performance. Its multi-core throughput works out to 2,100 per core, 1,470 per thread and 535 per watt. Its computed efficiency index is 1,381. Its performance index is 127, so its overall performance is 27% 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 i7-13645HX scores 99,927 in integer math, 74,247 in floating-point math, 364,264 in compression, 21,094 in cryptography, 1,664 in physics simulation, 21,515 in vector SIMD, 113 in the prime sieve and 38,210 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 70% above in integer math, 62% above in floating-point math, 60% above in compression, 84% above in cryptography, 53% above in physics simulation, 39% above in vector SIMD, 69% above in the prime sieve and 69% 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.
