Intel Core i5-12400 vs Intel Core i5-14400

The Intel Core i5-12400 (Alder Lake S, 10 nm) was designed for the mainstream desktop market. It features 6 performance cores (P-Cores) and 12 threads.

With PCIe 5.0, 77 GB/s memory bandwidth, 8 MB L2 and 18 MB L3 cache, and Intel UHD Graphics 730, it offers a solid foundation. The Intel Core i5-14400 (Raptor Lake S Refresh, 10 nm) targets the same audience.

Its hybrid architecture includes 6 P-Cores and 4 efficiency cores (E-Cores), resulting in 16 threads. It supports PCIe 5.0, achieves 90 GB/s memory bandwidth, and has 10 MB L2 and 20 MB L3 cache, along with Intel UHD Graphics 730. In terms of performance, the Intel Core i5-14400 offers significantly higher multi-core performance and a noticeable advantage in single-core capability and gaming, supported by architectural improvements and larger cache.

Although the Intel Core i5-14400 can potentially consume more power under load, its efficiency and thermal design power (TDP) remain similar compared to the Intel Core i5-12400. The Intel Core i5-12400 stands out with a good price-performance ratio and is more cost-effective.

The Intel Core i5-14400 commands a higher price for its improved performance. The Intel Core i5-12400 is ideal for budget-conscious users with everyday requirements. The Intel Core i5-14400 is better suited for multitasking, more demanding applications, and slightly better gaming, if a higher budget is available.
