ANSYS Fluent performance/Watt Figure 15.
Figure 16 illustrates the energy efficiency of MILC. The metric used here is rating/Watt. The
PowerEdge M620 cluster provides approximately double the performance for less than double the
power consumed by the PowerEdge R820 cluster. Thus, the PowerEdge R820 cluster measures 16
percent lower energy efficiency than the PowerEdge M620 cluster. The 512 core PowerEdge M420
cluster provides double the performance for less than double the power consumption of the 256 core
PowerEdge M620 cluster. This results in the 37 percent better energy efficiency of the PowerEdge M420
cluster over the PowerEdge M620 cluster. The shared infrastructure of the 32 node PowerEdge M420
chassis clearly provides a benefit.
