ProsStrong multi-threaded performance Most affordable six core processor Includes Intel stock cooler Great gaming performance when paired with a graphics card
ConsRequires manual overclocking
Intel Core i5 8400 is the most budget friendly processor for gaming maniacs who have a light pocket but require high configuration processor to play games without any disruption or frame hitches. It is also a bliss for gamers who require extreme frame rate for high refresh rate gaming.
The Core i5 8400 has six high speed physical cores i.e. 2 additional cores as compared to its previous generation. It has a base frequency of 2.8 GHz and can turbo to a speed of 4.0 GHz for single threaded applications and workloads.
It has a Thermal Design Power (TDP) of 65 W with limitation of manual over-clocking. Hyper-threading is still missing in 8th Generation i5 processors same as its predecessors. Another limitation which is present in all Intel 8th Generation Coffee Lake CPU’s is they will only work with Z370 chipset motherboards.
We recommend MSI Z370-A PRO motherboard priced at around $111 (on Amazon.com) for Core i5 8400 based on its compatibility , features and price.

Intel Core i5 8400 Performance Review
Intel Core i5 8400 features six physical cores with a 2.8 GHz base frequency which is lowest amongst all its Coffee lake processors.The low base frequency may look bad but Intel’s turbo boost technology speeds up the frequencies to work faster in heavier workloads without overloading all of its physical cores. So Core i5 8400 turbo boost bins trail behind the more expensive i5 8600K only by 300 MHz.
The Core i5 8400 also has an impressive turbo boost speed of 4.0 GHz as compared to its low base frequency of 2.8 GHZ which can sound scary, but in terms of performance with fully loaded six cores it can perform at speed of 3.8 GHz which is pretty impressive !!!
In terms of heating, it may exceed its 65 W TDP but does not become overheated. So in comparison to its Kaby lake predecessors , you get 50% more cores and same or higher clock speeds.
The Core i5 8400 also includes an Intel cooler and fan in the same package making it a very great purchase for gaming geeks.
