Intel Core i5-12400 vs Intel Core i3-12100

The Intel Core i5-12400 and Intel Core i3-12100 are 12th generation "Alder Lake S" desktop processors, manufactured using Intel's 10 nm process.

Both support PCIe 5.0 and offer a maximum memory bandwidth of 77 GB/s, as well as integrated Intel UHD Graphics 730. The Intel Core i5-12400 is aimed at mainstream users with a need for higher performance, while the Intel Core i3-12100 represents a cost-effective option for everyday tasks.

The Intel Core i5-12400 features 6 cores and 12 threads, 8 MB of L2 cache, and 18 MB of L3 cache. The Intel Core i3-12100 offers 4 cores and 8 threads, with 5 MB of L2 cache and 12 MB of L3 cache. In single-core performance, both CPUs are comparable, with differences here being less than 10 percent.

However, in multi-core performance, the Intel Core i5-12400 shows significantly superior performance, which is considerably higher than that of the Intel Core i3-12100 in benchmarks. For gaming, the Intel Core i5-12400, thanks to its additional cores and larger cache, offers a more stable and higher frame rate, especially in games that benefit from more threads.

The integrated graphics unit of both CPUs is insufficient for demanding gaming. Both processors have a base TDP of 65 watts, which means moderate heat generation and cooling requirements. The Intel Core i5-12400 offers better value for money for more demanding applications and gaming, while the Intel Core i3-12100 is an excellent choice for budget systems and basic computer use.
