The Intel Core Ultra 5 245K is the objective winner of this comparison, securing victory in ten out of sixteen measured specifications. Its most significant technical advantage is its L2 Cache, which is 117% larger than that of the Intel Core i7-12700KF. This substantial improvement in cache capacity represents the primary performance differentiator between the two processors, establishing the newer model as the superior option across the majority of the evaluated hardware metrics.

Users prioritizing high-speed data access and modern architecture should choose the Intel Core Ultra 5 245K for its vastly superior cache performance. Conversely, the Intel Core i7-12700KF remains the better selection for workloads that rely heavily on parallel processing, as it offers 43% more threads than the newer component. Select the former for cache-sensitive tasks or the latter if your specific computing requirements demand a higher thread count for multitasking efficiency.
