The Intel Core i5-14400 is the objective winner of this comparison, securing more total spec victories than the AMD Ryzen 7 3700X. While the Ryzen 7 3700X maintains a notable lead in L3 cache capacity, which is 60% larger than its competitor, the Intel Core i5-14400 provides the most significant technical advantage in this matchup. Specifically, the Intel processor features an L2 cache that is 138% larger than the one found in the AMD alternative.

Users who prioritize the substantial L2 cache capacity offered by the Intel Core i5-14400 should select it for their build to take advantage of its superior memory architecture. Conversely, the AMD Ryzen 7 3700X remains a viable option for those who specifically require the 60% larger L3 cache provided by that processor. Choosing between these two components depends entirely on whether your specific workload benefits more from the increased L2 cache or the larger L3 cache capacity.
