The AMD Ryzen 7 5800X3D is the objective winner of this comparison, securing more wins across the evaluated specifications. Its most significant advantage is the L3 Cache, which is 500% better than that of the Intel Core i9-11900K. This substantial disparity in cache capacity serves as the primary differentiator between the two processors, providing the AMD Ryzen 7 5800X3D with a clear technical lead in this head-to-head evaluation of their respective hardware capabilities.

Users prioritizing memory-intensive tasks should choose the AMD Ryzen 7 5800X3D to leverage its superior L3 Cache advantage. Conversely, the Intel Core i9-11900K remains a viable option for those who specifically require a higher Boost Clock, as it maintains an 18% advantage in that category. Selecting between these two components depends on whether your specific workload benefits more from the massive cache capacity of the former or the increased frequency offered by the latter.
