Should I learn more about the core factor table?

Generally, Microsoft does not recommend learning about the core factor table because SQL Server 2016 specifies a 4 core minimum for physical cores on a server in the SPUR (instead of a reference to a table published on Microsoft.com). New devices do not ship with single core & dual core processors. You may only use the table if you license SQL Server 2014 and earlier versions for use on multi-core AMD processors and you reported these versions under SPLA before June 1, 2016. In this limited scenario, the table may reduce the number of SQL core licenses required in SPLA.
