Hello everyone,
I would like to know why my HD6970 is crunching a PPS unit during 26 minutes when a GTX 580 is only crunching on 5 minutes :(
Thanks ! |

PPS uses Cuda on nVidia-cards and OpenCL on ATI.

I wouldn't worry so much about a nVidia card being faster than your ATI, that's how it is here at Primegrid. I would worry more about why is your card only half as fast as my 5870, which takes around 875s for a WU (at the moment I don't have any results to show, as I ran my caches dry for the challenge, but when it starts, check here). You will see 2 different run times, the longer, of around 2450s are from a 4870.

Thanks for the answers :)
Do you know if an app for HD6970 is planned ? |

There is one OpenCL-app for all ATI-cards.

I have a HD 4350 and it is taking about 8 hours per WU - what is going on - do I ahve to change any setting to speed it up? |

Could be your running 1 at a time while he's running 2 at a time. his times seem about right for 2 at a time as their a little faster than my 5870's running 2 at a time ...

No, you can't do anything. OpenCL is not the fastest.
If you would let run the OpenCL-app on a nvidia-card, you see the same losing in performance...

With an ATI double-precision Card I would crunch Milkyway@Home, there App is optimized for ATI.
