The Intel Core Ultra 7 270K Plus is the objective winner of this comparison, securing victory in ten out of sixteen measured specifications. While the Intel Core i5-14400F holds a notable advantage in power efficiency, boasting a 48% better TDP, the Ultra 7 270K Plus dominates in memory architecture. Its most impactful advantage is a 321% larger L2 cache, which provides a significant technical lead over the i5-14400F across the majority of the evaluated categories.

Users prioritizing raw technical capacity and the benefits of a substantially larger L2 cache should select the Intel Core Ultra 7 270K Plus for their build. Conversely, the Intel Core i5-14400F is the superior choice for those who require a more power-efficient component, as its TDP advantage makes it the more conservative option regarding energy consumption. Your final decision should depend on whether you value maximum cache performance or lower power requirements.
