Intel Core i5-10400F vs Intel Core i3-12100F

The Intel Core i5-10400F (Comet Lake S, 14 nm), introduced Q2 2020, offered 6 cores and 12 threads with 12 MB L3 cache, PCIe 3.0, and a maximum memory bandwidth of 43 GB/s.

The Intel Core i3-12100F (Alder Lake S, 10 nm), available since Q1 2022, features 4 cores, 8 threads, 5 MB L2 and 12 MB L3 cache, supports PCIe 5.0, and a maximum memory bandwidth of 77 GB/s.

In performance tests, the Intel Core i3-12100F significantly outperforms the Intel Core i5-10400F in single-core performance. Even in multi-core tasks, the Intel Core i3-12100F often achieves comparable or slightly better performance, despite fewer cores, thanks to its more efficient 10 nm architecture.

For gaming scenarios, the Intel Core i3-12100F is the better choice due to its superior single-core performance and more modern PCIe 5.0 connectivity. Its 10 nm manufacturing also enables higher energy efficiency compared to the 14 nm of the Intel Core i5-10400F. In terms of price, the Intel Core i3-12100F offers better value for money and a more future-proof platform.

The Intel Core i5-10400F is more suitable for existing LGA1200 systems as a cost-effective upgrade or for very budget-conscious multi-thread applications. For most new purchases and gaming focus, the Intel Core i3-12100F is clearly recommended.
