Super Pi is used by a huge audience, particularly to check stability when overclocking processors. If a system is able to calculate PI to the 2 millionth place after the decimal without mistake, it is considered to be stable in regards to RAM and CPU.
We used Super Pi's '32M' benchmark setting.
Super Pi's single-threaded workload loves processor frequency which is exactly why the overclocked Core i5 in Aria's system bundle manages to outperform the stock-clocked i7 in our 4770K test machine.
