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.
Completing the Super Pi benchmark in 7 minutes and 21 seconds shows that the 4.7GHz 3570K's single-threaded performance is similar to that of a 4.6GHz i7 3770K… in this benchmark at least.
