The Intel Core Ultra 5 245KF is the objective winner of this comparison, securing victory in twelve out of fourteen measured specifications. Its most significant technical advantage is its L2 cache, which is 1200% larger than that of the Intel Core i7-10700K. This substantial improvement in cache capacity represents the primary performance differentiator between the two processors, establishing the newer model as the superior choice across the vast majority of evaluated hardware metrics.

Users prioritizing modern architecture and the massive L2 cache advantage should select the Intel Core Ultra 5 245KF for their build. Conversely, the Intel Core i7-10700K remains a viable option for specific use cases that rely heavily on thread count, where it maintains a 14% advantage. Choosing between these components depends on whether your workload benefits more from the significantly expanded cache capacity of the newer processor or the higher thread count offered by the older model.
