The Intel Core Ultra 5 250KF Plus is the objective winner of this comparison, securing victory in eleven out of sixteen measured specifications. Its most significant technical advantage is its L2 cache, which is 216% larger than that of the Intel Core i5-12600KF. While the latter holds a 6% advantage in max turbo power, the superior cache capacity of the newer model provides a substantial architectural edge that defines its overall performance lead in this head-to-head evaluation.

Users prioritizing modern architectural efficiency and the benefits of a significantly larger L2 cache should choose the Intel Core Ultra 5 250KF Plus. Conversely, the Intel Core i5-12600KF remains a viable alternative for those specifically seeking the higher max turbo power capacity provided by that model. Your final selection should depend on whether you value the cache-heavy design of the newer processor or the specific power configuration offered by the older unit.
