The Intel Core Ultra 5 245K 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. This substantial increase in cache memory provides the newer processor with a clear architectural lead across the majority of the evaluated categories, establishing it as the superior option based on the provided hardware specifications.

Users prioritizing raw technical performance and modern architecture should choose the Intel Core Ultra 5 245K to leverage its massive L2 cache advantage. Conversely, the Intel Core i5-11600K remains a viable alternative for budget-conscious builders who prioritize a lower MSRP, which is 15% better than that of the newer model. Selecting between these two components depends on whether your primary goal is maximizing cache-heavy processing power or minimizing the initial cost of your build.
