The Intel Core i9-14900KS is the objective winner of this comparison, securing a lead in nine out of sixteen measured specifications. Its most significant technical advantage is the inclusion of E-Cores, which provide a 300% increase over the Intel Core i5-13400F. While the latter component maintains a lead in three categories, the superior core count and overall spec-win count establish the former as the more powerful hardware option for demanding computing tasks.

Users prioritizing maximum core density and high-end specifications should choose the Intel Core i9-14900KS to leverage its substantial E-Core advantage. Conversely, the Intel Core i5-13400F is the better choice for budget-conscious buyers, as it offers a 72% advantage in MSRP. Selecting between these two processors depends entirely on whether your primary requirement is the expanded processing capacity of the higher-tier model or the significant cost efficiency provided by the lower-tier alternative.
