The AMD Ryzen 9 3900X is the objective winner of this comparison, securing a higher number of superior specifications across the evaluated categories. The most impactful advantage held by this processor is its L3 cache capacity, which is 113% larger than that of the Intel Core i7-13700K. This significant lead in cache memory provides the primary technical edge for the Ryzen 9 3900X in this head-to-head evaluation of their respective hardware architectures.

Users prioritizing the substantial L3 cache advantage should select the AMD Ryzen 9 3900X for their system builds. Conversely, the Intel Core i7-13700K is the appropriate choice for those who specifically require the benefits of a larger L2 cache, as it outperforms the competitor by 300% in that specific metric. Selecting between these two components depends entirely on whether your workload benefits more from the superior L3 cache of the former or the L2 cache capacity of the latter.
