    Are you familiar with BOINC ? The BOINC client has now been ported to ARM and there is a growning set of Dhrystone MIPS and Whetstone MIPS that measured from (I expect) similarly compiled source code. I don't like Dhrystone MIPS (Weicker, author has also given it thumbs down) or the Whetstone benchmarks but we can directly compare the numbers as possibly being similar.

    My Linux Ivy Bridge Core i5 3450 3.10ghz measured BOINC
    3,151 FP MIPS (whet)/CPU and
    17,516 INT MIPS (DMIPS)/CPU.


    They have ported the BOINC client to run on Android and run the benchmarks on phones, tablets, laptops, desktops, workstations and servers. The DMIPS and Whetstone FLOPS are generated from small programs that run out of cache so the bus structure should not affect results.

    There are several BOINC STATS sites that accumulate the CPU data and AVERAGE CREDITS PER CPU SECOND for the larger less comparable workloads but the results are rather interesing.

    It seems like a 1.6ghz ARM v71 is about the same as an ATOM N450 1.66ghz. The metrics are PER CPU.
