The Intel Core i7-14700K is the objective winner of this comparison, securing a lead in nine out of sixteen measured specifications. Its most significant technical advantage is the L2 cache, which is 273% larger than that of the Intel Core i5-12400F. While the latter component holds its own in four categories, the superior cache capacity of the i7-14700K provides a clear architectural edge across the majority of the evaluated metrics.

Users prioritizing maximum hardware specifications and the substantial cache advantage should select the Intel Core i7-14700K for their build. Conversely, the Intel Core i5-12400F is the logical choice for buyers focused on the MSRP, where it maintains a 57% advantage over the alternative. Choosing between these two processors depends entirely on whether your primary requirement is the high-end cache capacity of the i7 or the significant cost-efficiency offered by the i5.
