Intel Core i5-10400F vs Intel Core i5-11400F

The Intel Core i5-10400F, based on the Comet Lake S architecture, was introduced in 2020 and is aimed at mainstream users as well as gamers looking for solid performance at an accessible price.

This processor, manufactured using a 14 nm process, features 6 cores and 12 threads with 12 MB L3 cache and utilizes PCIe 3.0. Its maximum memory bandwidth is 43 GB/s. In benchmarks, the Intel Core i5-10400F delivers reliable single-core and multi-core performance, sufficient for everyday tasks and many games.

Its Thermal Design Power (TDP) is moderate, and it often offers an attractive price-performance ratio. It is ideal for budget-conscious buyers. The Intel Core i5-11400F, a successor with Rocket Lake S architecture, was launched in 2021 and also targets the mainstream segment, but delivers noticeable improvements.

Also manufactured using a 14 nm process, it features 6 cores and 12 threads, complemented by 3 MB L2 cache and 12 MB L3 cache. A key advantage is the support for PCIe 4.0 and a higher maximum memory bandwidth of 51 GB/s. The Intel Core i5-11400F significantly outperforms its predecessor in single-core and multi-core performance.

In gaming, it benefits from higher single-core performance and PCIe 4.0, which can lead to smoother rendering with modern graphics cards. Under load, it may consume a bit more power, making a good cooling system advisable. It justifies its potentially higher price through performance gains and future-proof connectivity, making it the better choice for demanding users.
