Core i5-9400 is a planned 64-bit mid-range performance x86 desktop processor by Intel set to be introduced in late 2018. The i5-9400 is fabricated on Intel's enhanced 14nm++ process based on the Coffee Lake microarchitecture.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

Leaked Info! Some of the information presented in this article is solely based on leaks that were published online or obtained directly by WikiChip. It goes without saying that this information could change, be incomplete, wrong, or even made up. It's highly advised to wait for an official product announcement.

[Edit/Modify Cache Info]

Cache Organization

Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
