In the first SciMark composite test, the AMD system has its performance increased by 16% thanks to "Dirndl", but the 6-core Gulftown with Hyper Threading is boosted by 21%. Regardless, a 16~21% (or even 10%+) improvement via changing out part of the stack is a huge win.
The "Jacobi Successive Over-Relaxation" performance with Dirndl goes up by 22% for the AMD system and 20% for the Intel system.
With the Sparse Matrix Multiply algorithm, the AMD system is up by 10% with this soon-to-be-announced open-source initiative. With the Intel system, the Gulftown performance sadly regresses by a small margin.
