The Intel Core Ultra 7 265K is the objective winner of this comparison, securing victories in ten out of fourteen measured specifications. Its most significant technical advantage over the Intel Core i7-7700K is its L2 Cache, which is 3500% larger. While the older processor maintains a 64% lead in Max Turbo Power, the newer model dominates the majority of the evaluated categories, establishing itself as the superior component based on the provided data.

Users should choose the Intel Core Ultra 7 265K if they prioritize the massive L2 Cache capacity for their computing needs. Conversely, the Intel Core i7-7700K remains a viable option for those who specifically require the higher Max Turbo Power advantage provided by that unit. Selecting between these two processors depends entirely on whether your workload benefits more from the expanded cache architecture of the newer model or the power profile of the older one.
