The AMD Ryzen 9 5900X is the objective winner of this comparison, securing a lead across seven measured specifications. Its most significant advantage is the L3 Cache, which is 167% larger than that found in the Intel Core i5-14600K. This substantial capacity for high-speed data storage provides the primary technical edge for the Ryzen 9 5900X in this head-to-head evaluation of their respective architectural designs.

Users prioritizing the massive L3 Cache advantage should select the AMD Ryzen 9 5900X for their build. Conversely, those who require the superior L2 Cache capacity offered by the Intel Core i5-14600K should choose that component instead. Because the Intel Core i5-14600K features an L2 Cache that is 233% better than its competitor, it remains the preferred option for users whose specific workflows benefit most from that particular architectural strength.
