The Intel Core i7-14700KF is the objective winner of this comparison, securing a lead in nine of the sixteen evaluated categories. Its most significant technical advantage is its L2 cache, which is 273% larger than that of the Intel Core i5-12400F. While the latter component maintains a 54% advantage in Max Turbo Power, the superior cache capacity of the i7-14700KF establishes it as the more robust option across the majority of measured specifications.

Users prioritizing high-end performance and the benefits of a significantly larger L2 cache should select the Intel Core i7-14700KF for their build. Conversely, the Intel Core i5-12400F is the appropriate choice for those who specifically require the efficiency profile offered by its 54% advantage in Max Turbo Power. Selecting between these two processors depends on whether your primary requirement is the expanded cache capacity of the i7 or the power-related characteristics of the i5.
