Core i5-8400 is a 64-bit hexa-core mid-range performance x86 desktop microprocessor introduced by Intel in 2017. This processor, which is based on the Coffee Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process. The i5-8400 operates at a 2.8 GHz with a TDP of 65 W and a Turbo Boost frequency of up to 4 GHz. This chip supports up to 64 GiB of dual-channel non-ECC DDR4-2666 memory and incorporates Intel's UHD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1.05 GHz.

Cache[edit]

[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.
