The AMD Ryzen 7 5800X is the objective winner of this comparison, securing victory across eight of the fourteen measured specifications. Its most significant technical advantage is the L3 cache, which is 167% larger than that of the Intel Core i5-11600K. This substantial capacity increase represents the primary performance differentiator between the two processors, establishing the former as the superior option for users prioritizing cache-dependent operations and overall hardware specifications.

Users who require the highest available cache capacity should select the AMD Ryzen 7 5800X for their build. Conversely, the Intel Core i5-11600K is the better choice for budget-conscious buyers, as it holds a 42% advantage in MSRP. By choosing the Intel component, consumers can prioritize a lower initial cost, whereas selecting the AMD processor provides a significant technical edge in memory architecture that may benefit specific computing tasks.
