The AMD Ryzen 7 5700X is the objective winner of this comparison, securing a lead in eight out of fourteen evaluated specifications. Its most significant advantage is the L3 cache, which is 78% larger than that of the Intel Core i5-12400F. This substantial capacity difference represents the primary technical edge held by the Ryzen processor across the measured fields, establishing it as the more robust option based on the total count of winning categories.

Users prioritizing the benefits of a larger L3 cache should select the AMD Ryzen 7 5700X for their build. Conversely, those who place a higher value on L2 cache capacity should opt for the Intel Core i5-12400F, as it provides an 88% advantage in that specific area. Choosing between these two components depends on whether your requirements align more closely with the superior L3 cache of the former or the superior L2 cache of the latter.
