The Intel Core i5-14600KF is the objective winner of this comparison, securing victories in nine out of fourteen measured specifications. Its most significant technical advantage is the L2 cache, which is 700% better than that of the Intel Core i9-10900K. This substantial improvement in cache capacity represents the primary performance differentiator between the two processors, as the older model only manages to outperform the newer unit in a single specification category.

Users prioritizing modern architecture and superior cache capacity should select the Intel Core i5-14600KF for their build. Conversely, the Intel Core i9-10900K remains a viable choice only for those who specifically require its 6% higher base clock speed. Given that the newer processor dominates the majority of the measured fields, it serves as the more capable option for most computing tasks, while the older component is limited to its narrow advantage in base frequency.
