12-Core ARM Cluster Benchmarked Against Intel Atom, Ivy Bridge, AMD Fusion

Now it is time to look at the power efficiency results when all six PandaBoard ES boards making up this cluster were fully utilized using MPICH2.

When all six boards were idling, the average power consumption was 16.8 Watts.

With the EP.C workload on all twelve ARM cores, the average power consumption was 30.4 Watts for all six PandaBoards, which is in line with each PandaBoard burning through 5~6 Watts under load. When it comes to the performance-per-Watt, the EP.C test was yielding an average of 1.78 Mop/s per Watt, which was an increase over the single PandaBoard ES at 1.60 Mop/s per Watt.
