The Intel Core Ultra 5 245KF is the objective winner of this comparison, securing victories in eleven out of fourteen measured specifications. Its most significant technical advantage over the Intel Core i5-11600K is its L2 cache capacity, which is 767% larger. While the older processor maintains a lead in one category, the newer model dominates the majority of the technical fields evaluated, establishing a clear superiority in architectural specifications.

Users prioritizing modern hardware capabilities and the substantial L2 cache advantage should select the Intel Core Ultra 5 245KF for their build. Conversely, the Intel Core i5-11600K remains a viable option for budget-conscious buyers who specifically value its 8% better MSRP. Choosing between these two components depends on whether you require the significant cache capacity of the newer model or prefer the cost efficiency offered by the older processor.
