wattage processors and the lower DIMM configuration on the PowerEdge M420 contribute to the lower
power consumption.

Figure 13.
Figure 13 plots the energy efficiency of the three clusters when executing the LU benchmark. The
observation is that the PowerEdge M620 cluster and the PowerEdge M420 cluster have similar energy
efficiencies. The differences in the values are within the statistical variation. The PowerEdge R820
