The Intel Core Ultra 5 250KF Plus is the objective winner of this comparison, securing victory in ten out of sixteen measured categories. Its most significant technical advantage is the L2 cache, which is 216% larger than that of the Intel Core i5-14400F. This substantial increase in cache capacity provides the primary performance edge for the newer architecture, establishing it as the superior option across the majority of the evaluated hardware specifications.

Users prioritizing raw processing potential and cache-heavy workloads should select the Intel Core Ultra 5 250KF Plus to leverage its superior architectural advantages. Conversely, the Intel Core i5-14400F remains the logical choice for those who prioritize power efficiency, as it offers a 48% better TDP rating. Choosing between these two components depends entirely on whether your specific build requirements favor the increased cache capacity of the newer model or the lower power consumption of the i5.
