The AMD Ryzen 5 5500 is the objective winner of this comparison, securing a higher number of superior specifications across the evaluated fields. The most impactful advantage held by this processor is its base clock speed, which outperforms the Intel Core i5-12400 by 44 percent. This significant lead in base frequency provides the primary technical edge for the AMD Ryzen 5 5500 in this head-to-head evaluation.

Users prioritizing higher base clock speeds should select the AMD Ryzen 5 5500 for their build. Conversely, those who require superior memory architecture should opt for the Intel Core i5-12400, as it offers a 150 percent advantage in L2 cache capacity. Choosing between these two components depends entirely on whether your specific computing needs are better served by the higher base frequency of the former or the expanded cache size of the latter.
