Maximum Number of Processors Supported by the Editions of SQL Server

SQL Server supports the specified number of processor sockets multiplied by the number of logical CPUs in each socket. For example, the following is considered a single processor for purposes of this table:

  • A single-core, hyper-threaded processor with 2 logical CPUs per socket.

  • A dual-core processor with 2 logical CPUs.

  • A quad-core processor with 4 logical CPUs.

SQL Server is licensed per processor socket, and not per logical CPU basis.
