The AMD Ryzen 9 7900 is the objective winner of this comparison, securing victory across ten of the fourteen evaluated specifications. Its most significant technical advantage is the L3 cache, which is 220% larger than that found in the Intel Core i5-12600KF. This substantial capacity difference represents the primary performance edge held by the processor, establishing it as the superior option based on the total count of winning specifications.

Users prioritizing raw technical specifications and the benefits of a significantly larger L3 cache should choose the AMD Ryzen 9 7900. Conversely, the Intel Core i5-12600KF is the appropriate selection for buyers focused on the MSRP, where it maintains a 38% advantage over its competitor. Your final decision should depend on whether you value the cache capacity of the former or the cost-related advantage of the latter.
