The Intel Coffee Lake-S family was the first to bump the mainstream core count to 6 and it would be the first to go past that too. We have known for some time that Intel is working on a new core bump for the mainstream platform which would take the core count to 8 but there’s little info on this part available at the moment.

It has been more than a year since the release of the last Xeon E3 v6 family which was part of the 7th generation Kaby Lake family. While Intel did release mobile Xeon Mobile parts based on 8th generation Coffee Lake family, we have yet to see any new Xeon E v7 update. When Intel released the mobile Xeon E variants under the Coffee Lake family, there were two six-core parts, the Xeon E-2186M and the Xeon E-2176M.
