As we were conducting our first tests of AMD Phenom X4 9850, following the updated test procedure (with a newer version of MathWorks MATLAB), we noticed an odd phenomenon, utterly unexplainable by logic and common sense: results of Phenom X4 9850 in one of MATLAB benchmarks were many times worse than those of Phenom X3 8750 that had one less core and operated at a lower frequency. We could ignore this fact, since we are neither MATLAB developer nor Phenom engineers. All we can do is benchmark performance and publish results. However, a feeling of something unfinished surfaced each time we looked at AMD Phenom test results.
