The Intel Core i9-14900KS is the objective winner of this comparison, securing victory in eight of the sixteen evaluated categories. Its most significant technical advantage is the inclusion of E-Cores, which provide a 300% improvement over the Intel Core i5-12600K. This substantial increase in core count serves as the primary differentiator between the two processors, establishing the superior hardware configuration of the Intel Core i9-14900KS across the measured specifications.

Users prioritizing maximum core density for intensive multi-threaded workloads should select the Intel Core i9-14900KS to leverage its significant E-Core advantage. Conversely, the Intel Core i5-12600K is the logical choice for budget-conscious builders, as it holds a 59% advantage in MSRP. By choosing the latter, buyers sacrifice the higher core count for a more accessible entry point, making it suitable for those who do not require the extensive hardware specifications found in the higher-tier model.
