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

The next Atom 330 test was NPB LU.A.

The Atom 330 system had an average of 429 Mop/s with LU.A compared to 190 Mop/s on a single PandaBoard ES, 440 Mop/s on two PandaBoard ES, 579 Mop/s on three PandaBoard ES, and 915 Mop/s on all six PandaBoard ES units benchmarked.

The ARM cluster slaughtered the Atom 330 again in power efficiency: 11.98 Mop/s per Watt for the Intel x86_64 CPU while a single PandaBoard ES was at 38 Mop/s per Watt and 30 Mop/s per Watt for the entire cluster.
