1 Thread per GPU

post #1 of 4
Thread Starter 
Ok i understand Beta, and i understand its common knowledge right now for the ATI cards its eating 1 thread per GPU.
My question is two fold, hah get it fold.
anywho.....
First does anyone know why its uses both 100% of the thread and 100% of the GPU. i would think one or the other would be the bottle neck and if the thread couldn't keep up the GPU wouldn't be max or vise versa, My assumption right now is that when using 1 thread fully its actually using 1 core since the hyperthreading action.
My second question is my 5870 are netting about 1/4th what my i7 can get and if its eating 1 core per i am just breaking even by running with my GPU's at the cost of some crazy power.

Once again i know its beta and they are working out bugs and need testers. Just two questions on my mind.

The old core was worse, they are going to optimize it as time goes by so its less CPU usage.

You can try affinity and priority programs to see if you have luck optimizing.
Check the Essentials sticky for a list of them.

Well i guess what i meant was i was not folding on my GPU's at all before.
The impact on my CPU seems to be about breaking even

With one core dedicated to my 6870 I'm doing ~3-4000 more PPD now than I was with just SMP on all 6 cores. I have not found a better method yet to increase efficiency but not going to give up either. This is the first time ever I have been able to get some kind of benefit from my GPUs and I'm bound to get the most from it.
