The Intel Core Ultra 7 265F is the objective winner, securing victory in 11 out of 14 comparable specifications. Its most significant advantage over the Intel Core i7-7700K is its L2 cache, which is 3500% larger. While the older processor maintains a lead in base clock speed, which is 75% higher, the modern architecture of the newer component provides a substantial technical lead across the vast majority of measured categories.

Users prioritizing modern architectural efficiency and the massive L2 cache advantage should choose the Intel Core Ultra 7 265F for their build. Conversely, the Intel Core i7-7700K remains a viable option for specific use cases that rely heavily on a higher base clock speed. Select the newer model for broad technical superiority, or stick with the older unit if your specific requirements favor its higher base frequency.
