Intel has announced the discontinuation of various 8th-gen former Coffee Lake Core i3-, i5- or i7 processors as of June 1, 2020. Accordingly, they mostly comprise desktop processors, as well as the i3-8100B, i5-8500B and i7-8700B mobile chipsets.
This new EOL notice also applies to the Celeron G4900 and G4920, as well as the Pentium Gold G5400, G5500- and G5600-series. The latter are all desktop processors clocked from 3.2 to 3.9GHz. However, the news that the i7-8700K will no longer be sold soon may be of most interest to consumers or prosumers.
The range of chipsets - including all of their boxed units - will remain on shelves until December 18, 2020, and will become non-returnable on that date. They will continue to be shipped until June 4, 2021. Therefore, those interested in building a rig using, say, the 3.6GHz Core i5-8600K may be in line for a good deal soon.
