ppd for seti with different gpus

[bryanW1995]

Ok, I just bought a gtx 260 on ebay yesterday. You know, because my legend of zelda emulator needs more graphical horsepower, and sli gtx 260's looks like just what the dr ordered. and, um, I might crunch some seti with it as well.

this has gotten me thinking, is there a list of seti ppd on various gpus? I remember seeing one for milky way that gave a big advantage to amd gpus, and I've heard that folding@home and seti@home do better with nvidia, but I haven't seen any stats. Also, does it make a difference if you're using an i7 @ 3.8 vs a q6600 @ 3.2 vs an athlon x2 @ 2.4? I have never run my i7 rig without the gpu in it so I'm unsure what the ppd difference will be on my gtx 260, but it might also be nice to know the ppd value on other gpus as deals become available.

Please post your results to this thread and I'll update the OP.

found an older link, but nothing on fermi.

from looking at the seti@home message boards it looks like a lot more, but I didn't see any actual ppd numbers.

if you go into the seti forums, or i think it was lunatics, there is an ap schedular somewhere that will convert cpu wu to gpu wu and vice versa... it was a really handy ap.

and i recall that this ap prevented certain wu from running on the gpu because it would stall forever and then error out at the end of time..
... there's your answer Bryan about the wu erroring out.. i just remembered this little tidbit..
I haven't crunched seti in a six months.. i don't know if they changed this since then.

I haven't crunched Seti since last year's Gauntlet and I don't remember how many ppd my GTX295 was producing. I checked out some of the top computers at Seti@home with the thought of coming up with some numbers by looking at validated GPU WUs, but the numbers are all over the place. I also checked the lunatics forum for numbers and couldn't find any.
