    Of course not, but if multiple benchmarks are slower on average 25-35%, that's tells us that something is wrong, or the marchitecture is flop.
    For "pi" wprime is more up to today's standard.
    wprime is more integer than float and uses numerical method to calculate square root. So, it measures integer multithread performance, not FP.

    1.6Ghz Bobcat in super pi gets a score of 49s => 4.2Ghz should get ~18.7s
    1.6Ghz Bobcat in wprime (2 thread/cores) gets a score of 72.1s => 4.2Ghz should get ~55s in single core test

    So 4.2Ghz Bulldozer core which in single thread workload such as super pi has 128bit fmac on its disposal is slower than Bobcat @ 4.2Ghz by 6% and in wprime is faster by 6%. Bobcat has 64bit FPU. It does look weird. So even if someone has a hardware that posts those scores (real hardware,not faking benchmarks),it may not be final platform.
    Interesting comparison. There isn't chance for BD to be slower per clock than Bobcat.
