Adobe Photoshop and Microsoft Excel are two popular applications where Phenom II processors do not do too well. It is also true for the new Phenom II X4 810 that loses to Core 2 Quad Q8200 by 9% and 17% respectively.
Phenom II X4 810 demonstrates acceptable performance in Wolfram Mathematica 7, even though it is still a little slower than the junior Core 2 Quad.
However, archiving in WinRAR works real well for the new AMD CPU, much better than in the previous cases.
Computational tasks with integer arithmetic are not the best environment for CPUs on Stars (K10) microarchitecture. Two diagrams above prove this point correct.
