I am currently running a GTX 650Ti GPU, running two tasks at a time.

In seeing the better performing GPUs, what is it that leads to their better crunching performance, their speed, or are they running many more tasks at the same time (or some combination)?

2 tasks should be pushing a 650ti to 100% usage.

I would run your CPU though, it should do a lot of work, you don't have any tasks on it.

Try

<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.5</cpu_usage>

With 1 free core you likely won't even notice the CPU is being used.

Hey PKnowles,


It's a combination of things.


Yes the newer card do crunch faster. Plus there is the ability of those cards to carry more work units at the same time.

With the new Maxwells, you can get just as much work done on the GPU as with the previous generation but with lower electric use and lower Temps.

That last part allows you to push the cards more than before since there may not be any throttle down due to overheating. (running more work units per card...depending on the card anywhere from 3-4 work units per card)

After the cards, playing with the mbcuda.cfg helps to speed up processing of multibeams and inserting commands into the commandline for Astropulses.

I also had some 650Ti but upgraded. Compared to those, my newer cards tear thru work units.

Hope this helps,

Zalster

Thanks, guys.

Brent, I am crunching on CPU, but I am sharing with another project and have trimmed down a little bit for the summer (ambient heat) months. Just one CPU core for now, mostly running a project in World Grid.

Zalster, thanks for the explanation. I'm going to leave things as they are; this is primarily my work PC, built for work, plus some decent (from my persepctive) crunching. It ain't broke, so not fixing! ;-)
