The Intel Core i5-14600KF is the objective winner of this comparison, securing victory in eight of the sixteen evaluated categories. Its most significant technical advantage is its L2 cache, which is 167% larger than that of the alternative. While the Intel Core i5-12400F holds its own in five categories and maintains a 48% advantage in TDP, the superior cache capacity of the 14600KF establishes it as the more robust component across the majority of the measured specifications.

Users prioritizing power efficiency should select the Intel Core i5-12400F, as it offers a significantly lower TDP. Conversely, those who require the performance benefits associated with a substantially larger L2 cache should choose the Intel Core i5-14600KF. By focusing on these specific advantages, buyers can align their choice with either the energy-conscious profile of the 12400F or the cache-heavy architecture of the 14600KF to best suit their individual system requirements.
