'''Core i5-8400B''' is a {{arch|64}} [[hexa-core]] mid-range performance [[x86]] desktop microprocessor introduced by [[Intel]] in early [[2018]]. This processor, which is based on the {{intel|Coffee Lake|l=arch}} microarchitecture, is manufactured on Intel's 3rd generation enhanced [[14 nm process|14nm++ process]]. The i5-8400B operates at a 2.8 GHz with a TDP of 65 W and a {{intel|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 {{intel|UHD Graphics 630}} IGP operating at 350 MHz with a burst frequency of 1.05 GHz.
