SQL Server According to Bob

JUNE 6, 2016

As indicated, SQL Server 2016 added the use of SSE and AVX instructions in various code paths to improve performance. SQL Server asks the CPU if it supports SSE or AVX in order to determine the level of hardware support present on the system. My recent posts. have generated discussions about the SSE and AVX support boundaries.
