The AMD Ryzen 5 3600 is the objective winner of this comparison, securing a higher number of superior specifications across the evaluated fields. Its most significant advantage is the L3 Cache, which is 100% better than that of the Intel Core i9-11900K. While the Intel Core i9-11900K maintains a lead in total core count, the overall spec-win count favors the AMD Ryzen 5 3600 as the more balanced component in this head-to-head assessment.

Users prioritizing memory architecture efficiency should choose the AMD Ryzen 5 3600 for its substantial L3 Cache advantage. Conversely, those who require a higher total core count for their specific computing needs should opt for the Intel Core i9-11900K, which offers a 33% improvement in that category. Selecting between these two processors depends entirely on whether your workload benefits more from the cache capacity of the former or the core density of the latter.
