The Intel Core Ultra 5 245K is the objective winner of this comparison, securing victory in eleven out of fourteen measured specifications. While the Intel Core i7-7700K maintains a 43% advantage in Max Turbo Power, the Intel Core Ultra 5 245K provides a significantly more robust architecture. Its most impactful technical advantage is a 2500% larger L2 Cache, which serves as the primary differentiator between these two processors across the evaluated categories.

Users should choose the Intel Core Ultra 5 245K if they prioritize the massive L2 Cache capacity for modern computing tasks. Conversely, the Intel Core i7-7700K remains a viable option for specific use cases that rely on its superior Max Turbo Power rating. Selecting between these components depends entirely on whether your workload benefits more from the expanded cache architecture of the newer model or the specific power profile offered by the older processor.
