The Intel Core i3-13100F wins in 11 out of 14 comparable specs, with 1 tie. Its biggest advantage is L2 Cache (233% better).
Core i5-8400 wins in 2 specs (Total Cores: 50% better).
Recommendation
Choose Core i3-13100F if you want the best overall performance — especially l2 cache.
Choose Core i5-8400 if total cores matters more to you.
AI Versus Verdict
The Intel Core i3-13100F is the objective winner of this comparison, securing victories in 11 out of 14 measured fields. Its most significant technical advantage is its L2 cache, which is 233% larger than that of the alternative. While the Intel Core i5-8400 maintains a lead in total core count, the superior cache capacity of the newer processor provides a substantial architectural edge that defines its overall performance profile across the majority of the evaluated specifications.
Users prioritizing modern architecture and the efficiency of a significantly larger L2 cache should choose the Intel Core i3-13100F for their build. Conversely, the Intel Core i5-8400 remains the appropriate selection for those who specifically require a 50% higher total core count for their computing tasks. By weighing the benefits of cache size against the total number of cores, buyers can align their choice with the specific technical strengths offered by each processor.
