Nice article in general.
However, I'm disappointed and concerned to see your selection of scientific benchmarks ever-decreasing. For example, in this particular test, it would have been informative to use at the very least the BLAS benchmarks offered in ScienceMark; you also used to use MathematicaMark 5.2, but you've stopped using this as well. Primordia pretty obviously doesn't scale at all with memory bandwidth, but there are plenty of other applications that you could have tried that do--in short, of all the available options for scientific benchmarks, you seem unfortunately to have picked the worst.
Please, please start using a wider range of applications again, and if possible, also start using MathematicaMark 6, MATLAB 2007a, and Multiphysics as well. These modern applications are much more capable of taking advantage of the performance of current processors, and hence much better as benchmarks, than the ancient ScienceMark Primordia test. In particular, all of them (with sufficiently large datasets) have strong dependence on memory performance.
