    Single-Board Computers on BOINC compared

    There are more and more SBCs on the market, but which one is best for BOINC?

    As logic has it, one has to have the latest of the latest in order to get the best (and most efficiënt) performance.
    Does this hold true in the realm of the creditcard sized mobos?

    Some things that stand out:
    • The strange influence of the OS on Floating Point and Integer MIPS with the Beaglebone (and perhaps with the Banana Pi M2 as well).
    • The low reported Integer MIPS of the Banana Pi M2, compared to its Floating Point performance. These are real-life (Android) figures as measured by our team member Chris Skull, who also supplied the Odroid C1 figures.
    • The double Raspberry Pi 3 MIPS figures. They are for a power supply that does not give enough Amps (2A) vs one that does (3A).
    • The difference in CPU features between the two ARMv8 ARM Cortex-A53 CPUs, Broadcom having decided to also support the almost full ARMv7-A instruction set and Hardkernel betting on the instruction set features for the ARMv8-A -and then only a few of them. The ARMv8-A 48-core (!) Cavium ThunderX e.g. features fp, asimd, evtstrm, aes, pmull, sha1, sha2 and crc32.
