Intel Core i5-8400 vs Intel Core i5-14400F

The Intel Core i5-8400, based on the Coffee Lake S architecture, was introduced as a mainstream desktop processor.

It is manufactured using the 14 nm process and features 6 cores and 6 threads, making it suitable for everyday tasks and older applications. The integrated graphics unit is the Intel UHD Graphics 630. With PCIe 3.0 and a maximum memory bandwidth of 43 GB/s, it offers a solid foundation for its generation, with 9 MB of L3 cache.

In terms of performance, it shows basic single-core and multi-core performance sufficient for standard tasks. Its TDP is typically 65W. For gaming, it is suitable for older or less demanding titles and is primarily relevant today in the used market. The Intel Core i5-14400F, based on the newer Raptor Lake S Refresh architecture, is a current desktop processor without an integrated graphics unit.

It is manufactured using the 10 nm process and utilizes a hybrid architecture with 6 Performance-cores (P-Cores) and 4 Efficient-cores (E-Cores), resulting in a total of 10 cores and 16 threads. This enables significantly higher parallel processing power. It supports PCIe 5.0 and achieves a maximum memory bandwidth of 90 GB/s, which considerably accelerates data transfer.

It offers 10 MB of L2 cache and 20 MB of L3 cache. In benchmarks, it shows significantly superior single-core and multi-core performance. Its TDP is also 65W, but it can draw significantly more power under load. For modern gaming, it offers much better performance and represents a future-proof platform.
