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 pace after the decimal without mistake, it is considered to be stable in regards to RAM and CPU.
In Super Pi, the Intel i3-2105 beats the A8-3850 APU, managing to calculate Pi in about half the time. Bear in mind that this application doesn't utilise all cores so the AMD benefit of double the physical cores is negated.
