The Intel Core Ultra 5 235F is the objective winner, securing victories in 12 out of 14 comparable specifications. While the Intel Core i7-8700K maintains a 17% advantage in Max Turbo Power, the newer processor dominates in memory architecture. The most impactful technical improvement is found in the L2 Cache, where the Intel Core Ultra 5 235F provides a 1233% increase over the Intel Core i7-8700K, significantly enhancing its data handling capabilities.

Users prioritizing modern architecture and superior cache capacity should select the Intel Core Ultra 5 235F for its broad lead across the majority of measured specifications. Conversely, the Intel Core i7-8700K remains a viable option for specific builds where the 17% advantage in Max Turbo Power is the primary requirement. Choosing between these two components depends on whether your workload benefits more from the massive cache expansion or the specific power profile of the older unit.
