GTX 550 Folding Performance

but what would the ppd/watt be like in comparison to a 460 doing the same ppd? If it takes 1000mhz to do the same ppd as a 460, then the price difference may get wiped out by the extra power. No idea really, just speculating
 
It looks like these cards are more expensive than the GTX 460, which makes them pretty pointless in my opinion.

Agreed, they are way off the mark on price. However, the 450 quickly dropped below $100 and if this does the same (and it should, it is nearly beat by a 5770 for gaming) then it would be a good value folder. The article also mentions the 768mb 460 is disappearing so this will likely drop into that price point.
 
I don't see why there is still so many 400 series cards around. They should just drop the price to loose the stock :)

Ball park guess.......10-11K PPD? I'd pay $130 shipped. :)

Must be more than that. My GTS 450 produces very close numbers to that. I've seen 10.7K PPD on some WUs.

What clocks and voltage if I may ask?

I average about 9K PPD on mine. Sometimes less, sometimes over 10K (rarely). I was guessing just under what my GTX460 does which is around 12K. I'm wondering if running them on an old PCI-E ver 1.0 Socket 939 motherboard has something to do with it.

Right now, core clock is at 980/1960MHz, memory at 2000MHz and voltage is 1.087. I've had the clocks a bit higher but wasn't seeing that much greater performance and decided to dial it down a bit. To take advantage of higher clocks I think I will need to increase the memory speed substantially if I want to break the 11K PPD barrier. Temps are still quite a bit under 40.

I think we are probably just running different clock speeds. The performance gap isn't that big between our two cards. The worst I've seen with my card is ~9440 PPD running the P6800 WU.

That completely trounces my GTX280 output but the 280 is miles better in games, its too bad they never fixed GPU3 for GT200.

I just saw they have single slot GTS 450's, that makes a pretty attractive physx or SFF card.

Those clocks and temps are crazy! I'm happy to keep my cards stable at 900/1800 with 1027mV, 1830MHz memory. 40C? Are they watercooled? Naked?

I'm surprised more people aren't reporting similar figures to mine. I never water-cool anything nor likely ever will. The card is running the stock cooler, it's an Asus GTS 450. I also have a 120mm fan blowing on the card from the side but in all honesty it isn't required at these temps. Without the fan it will climb close to 40 or just above. The system is in an open case, though, and that does make a difference when running cards that do not exhaust at the rear. Also, the system is in an unheated basement and I'm located in Canada, certainly the low ambient temps help some.

BTW, I had OCed the card all the way to 987MHz, but I didn't see any siginificant performance increase above the clocks I am running now. The temps shot up to around 45, which was a substantial jump from what I am seeing now. However, there seems to be a performance wall at around the 980MHz mark. I'm suspecting the memory isn't keeping up but do not want to push the memory clocks much above 2GHz. I've had BSODs doing that with GPUs in other systems, which is much worse than an EUE from a core/shader frequency OC, so I'm satisfied with what I've got. The card exceeded my expectations by substantial margin, sometimes you got to know when it's time ease on the clock tinkering, LOL. :p
 
In a well ventilated case I was able to get my 0.975V GTX 460 stock cooler down to 43C with 19C room temps and max fan speed. The stock cooler design is amazing if you can keep hot air from building up in the case.

Nice. Which brand, BTW?

One of these at 850mhz and 0.975V on a 6806 wu. I think at max the fan runs at 4krpm but it is only a 80mm fan so it isn't screaming loud. The stock cooler is really nice, you just need to feed it cool air:

Apollo, you woudn't happen to have some frozen sides of beef hanging in your basement do you? Those are awesome temps!

I know, I still can't believe it and posted about that on the forum a few times since getting the card. The room is cool but not what I consider very cold, not the past few weeks in any case. Without the low temps, I seriously doubt I cvould have maintained these clocks the past few months. I'm sure if I continue folding into the warmer months things will probably change.
