The Intel Core i7-14700 is the objective winner of this comparison, securing victory in eight of the sixteen evaluated categories. While the Intel Core i5-12400 holds a notable 47% advantage in Max Turbo Power, the Intel Core i7-14700 provides a significantly more substantial lead in memory architecture. Specifically, the Intel Core i7-14700 offers a 273% advantage in L2 Cache, which serves as its most impactful technical superiority over the Intel Core i5-12400.

Users prioritizing raw cache capacity for complex computational tasks should select the Intel Core i7-14700 to leverage its superior L2 Cache architecture. Conversely, the Intel Core i5-12400 is the appropriate choice for those who specifically require the higher Max Turbo Power efficiency provided by that unit. Choosing between these processors depends entirely on whether your workload demands the expanded cache resources of the former or the specific power profile of the latter.
