The AMD Ryzen 9 7900 is the objective winner of this comparison, securing victories in thirteen out of fourteen evaluated categories. Its most significant technical advantage is the L3 cache, which is 300% better than that of the Intel Core i9-11900K. This substantial lead in cache capacity represents the primary differentiator between the two processors, as the Intel Core i9-11900K failed to outperform its competitor in any of the measured specifications.

Users prioritizing modern architecture and superior cache capacity should choose the AMD Ryzen 9 7900 for their system builds. Because the Intel Core i9-11900K did not secure a win in any of the fourteen fields, it lacks a technical justification for selection against this specific competitor. Those seeking the most capable component based on these specifications will find the AMD Ryzen 9 7900 to be the clearly superior option for their computing needs.
