About two months ago our beloved Turrican passed away in a horrible car accident. He was a big part of our community and is still Austrias only overclocking lengend! Out of my sadness and anger I started to work on this project as a virtual monument, something to honour him in our scene. It's an homage to SuperPI, that Turrican benched on every possible platform, an application that calculates pi completely parallelized on a graphics card. So let's get our gear going and do exactly what our Karl showed us in all his years: Bench the hell out of it!

I got running i5-2500K@4.5GHz and GTX 580@reference-stock 3GB-344.60WHQL:
At 32 millions-digit:
-> GPU

result: 0.681s

-> CPU

result: 17.313s

GPU is 25.4x faster than CPU! :D


GPU - 1 billion-digit: :D

result: 57.095s
