The Intel Core i3-14100F 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 233% larger than that of the alternative. This substantial improvement in cache capacity serves as the primary driver for its superior performance across the majority of the evaluated metrics, establishing it as the more modern and capable component in this head-to-head matchup.

Users prioritizing high-speed processing and modern architecture should choose the Intel Core i3-14100F for its significant cache advantage. Conversely, the Intel Core i5-10400F remains the appropriate selection for tasks that specifically benefit from a higher core count, as it offers 50% more total cores than the newer model. Selecting between these two processors depends entirely on whether your specific workload requires the increased cache efficiency of the newer architecture or the higher core density of the older unit.
