The Intel Core i5-12400F wins in 8 out of 14 comparable specs, with 3 ties. Its biggest advantage is L2 Cache (400% better).
Core i7-8700K wins in 3 specs (Base Clock: 48% better).
Recommendation
Choose Core i5-12400F if you want the best overall performance — especially l2 cache.
Choose Core i7-8700K if base clock matters more to you.
AI Versus Verdict
The Intel Core i5-12400F is the objective winner of this comparison, securing a lead across eight of the fourteen evaluated specifications. Its most significant technical advantage is the L2 cache, which is 400% larger than that of the Intel Core i7-8700K. This substantial increase in cache capacity provides the primary performance edge for the newer processor, establishing it as the superior option based on the total number of winning metrics across the board.
Users prioritizing modern architecture and the efficiency of a significantly larger L2 cache should select the Intel Core i5-12400F for their build. Conversely, the Intel Core i7-8700K remains a viable choice for those who specifically require a 48% higher base clock speed for their computing tasks. Choosing between these two components depends entirely on whether your workload benefits more from the expanded cache capacity of the newer model or the higher base frequency of the older unit.
