The Intel Core Ultra 5 245KF 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 174% larger than that of the Intel Core i5-14400F. While the latter component holds its own in four categories, the superior cache capacity of the Ultra 5 245KF provides a substantial architectural edge that defines its lead in this head-to-head assessment.

Users prioritizing power efficiency should select the Intel Core i5-14400F, as it offers a 48% advantage in TDP compared to its counterpart. Conversely, those who require the enhanced memory architecture provided by the significantly larger L2 cache should opt for the Intel Core Ultra 5 245KF. Choosing between these two processors depends entirely on whether your specific build requirements prioritize lower power consumption or the performance benefits associated with a vastly expanded cache.
