Memory performance - Stream

Website: University of Virginia

Stream is a synthetic memory bandwidth benchmark developed by John McCalpin at the University of Virginia.

It comprises four individual tests, each of which represents a typical long vector operation, a typical workload in server and HPC applications.

Unfortunately, the Windows version of Stream is hardcoded to support 1, 2, 4, 8, 16 or 32 threads, not the 24 threads native in both of the test systems in this review. For this reason we ran Stream with the 16 thread profile enabled.
