    The benchmarks on those pages use a number of algorithms to test various aspects
    of floating point and integer CPU/System performance respectively.

    : -I presume with UMA's strengths, you talk of the I/O benefits?
    : As far as being better of: the o2 is going to be used for

    : The o2 is much quieter, so otherwise the Octane would be the favorite.

    UMA's strengths are primarily in the areas of 3d texturing using video as
    texture or using jumbo textures. The O2 also has the benefit of having very
    cheap and available video IO.

    The Octane can be a bit noisy if the ambient temperature is above 25c, otherwise
    it's not too bad.
