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

Now to look at the power efficiency, which will then be compared to a few other systems. First is looking at the PandaBoard ES power efficiency when using a single OMAP4460 board followed by the results for maxing out all six PandaBoard ES boards in the cluster.

While idling, the single PandaBoard ES was consuming around 3.9 Watts as measured by the WattsUp AC power adapter.

With the load generated by the EP.C workload with the NAS Parallel Benchmark, the average power consumption with both ARMv7 A9 cores being fully utilized, the average power consumption was 6.4 Watts with a peak of 6.6 Watts.
