The Intel Core Ultra 7 270K Plus is the objective winner of this comparison, securing victory in ten out of fourteen measured specifications. Its most significant technical advantage is its L2 cache, which is 1233% larger than that of the alternative. While the Intel Core i5-11400F falls behind in the majority of categories, it maintains a notable lead in power efficiency, offering a TDP that is 48% better than the higher-performing model.

Users prioritizing raw technical specifications and memory-heavy operations should select the Intel Core Ultra 7 270K Plus for its superior cache capacity. Conversely, the Intel Core i5-11400F is the appropriate choice for builders who prioritize power efficiency and lower thermal output over the advanced architectural advantages found in the newer processor. Each component serves a distinct need based on whether the user values maximum cache performance or a more conservative power profile.
