The Intel Core Ultra 7 265K is the objective winner of this comparison, securing victory in eleven out of sixteen measured specifications. While the Intel Core i5-12600KF maintains a 40% advantage in Max Turbo Power, the Intel Core Ultra 7 265K provides a significantly more robust architecture. Its most impactful technical advantage is a 279% larger L2 cache, which serves as the primary differentiator between these two processors across the majority of the evaluated categories.

Users prioritizing raw cache capacity for demanding computational tasks should select the Intel Core Ultra 7 265K to leverage its superior architectural specifications. Conversely, the Intel Core i5-12600KF remains the appropriate choice for those who specifically require the higher Max Turbo Power capacity provided by this model. Each processor offers distinct advantages, so buyers should align their final decision with whether they value the expanded cache memory or the specific power profile of the alternative.
