    Octos compared for BOINC Performance

    You often read that people do not really need more cores because the existing software hardly makes use of those extra cores. While this is increasingly not true in itself, it is absolutely untrue in BOINC, where every core counts. I will show you some scores for octo-core Bulldozers and Piledrivers, compared against hexa- and quad-core Phenom II's and a quad-core Athlon that most of you will still be using.
    As with the quads I will break it up into project categories, starting with the Astrophysical ones (A. Because the 'A' comes first in the alphabet and B. Because WuProp has these values complete, unlike some other categories).
    Two first value is the maximum per core per day, the next is the value per CPU per day, multiplying the scores with 8 for octos, 6 for hexas and 4 for quads.

    This pretty much agrees with what I was saying, the 8150 even having two more cores, is only slightly better in some of the projects and worse in others, than a Phenom 1090T. Pretty frustrating after spending all that time an money upgrading, only to find I had to OC the heck out of it to match the 1090 I replaced. I kept looking around for a parachute or anchor attached to the 8150 that I could cut loose, but I still haven't found one. I'll keep looking, maybe it has electric brakes or hyperthreading I can utilize.

    I think you may have to wait for optimized applications that make full use of the extra instruction sets that Bulldozer supports as compared to Phenom

    After viewing your graphic Dirk, I now understand why the bulldozer is so slow, it takes a lot of power to turn those huge steel tracks to make it go.

    It might pay to obtain the sources for the various BOINC applications and re-compile them using an AMD compiler, read this

    With these resources we might be able to launch our own 'lunatics' builds (at least for Linux/RHES/SLES...)
