Partitioning allows SQL Server to scale to the largest systems with record-setting performance. When promoted to a super-latch on a 64 CPU system the memory requirement becomes 32 + (32 *64) = 2080 bytes. However, on smaller systems and VMs the partitioning may not be required to maintain performance. SQL Server 2019.
