Performance and Energy Efficiency of Dell PowerEdge servers with Xeon Cascade Lake

Memory subsystem performance
STREAM-triad
As CPU throughput performance grows so does the need for the main memory configurations that will maximize
aggregate data transfer rate. This is especially true for Cloud and in-memory database applications. Dell new PowerEdge
servers with select Cascade Lake-SP processor models support 2933 MT/s DDR4 system memory configurations up from
the 2666 MT/s of Skylake-SP. In figure 4, the server industry-standard STREAM-triad

metric illustrates the CLX + 2933M
solution provides a 4% uplift in total system memory read bandwidth over the previous SKL + 2666M one.
