Hello all!

I had a GeForce G210 wich has a theoretical processing power of 67 GFLOPs and I had a constant output of 100-105 credit/hour.

Now I installed a Quadro 600 wich has 246 GFLOPs and I get only 75-140 credits/hour.

Isn't it has to be around 400 credits/hour since the Quadro is 4 times as powerfull?

In both cases the GPU usage is 80-90% all the time.

I'm using the Lunatic's app.

Thank you.

It depends on the WU's being processed and the GPU power/RAC ratio isn't exactly a straight line. I'm sure someone will be along shortly to explain things better than I could
