    quite nice.
    it seems llvm likes c-ray but no chess.
    what id like to see now is a linux kernel (compiled with these different compilers) performance benchmark.

    a thing that bothers me aswell is the fact that there are being "regressions found" on intel cpu whereas there is a huge performance improvement on AMD (or vice versa). maybe one should take this into account when looking for regressions. as far as i remember there have only been benchmarks with intel hardware...
    and as the graphs show there really are some interesting splits in performance with different hardware

    While LLVM/Clang is not yet decisively faster than GCC, it is continuing to make great progress and does boast a different feature-set and focus from the GNU Compiler Collection.
    this template footer found in nearly every phoronix article, sounds like "please disregard this article, it's going to be obsolete soon"

    What happened there at graphics magic tests? Do the newer gccs utilize OpenMP that much better?
