I am considering purchasing an nVidia GTX 650 Ti for purely folding purpose. What kind of PPD do they get? In the ~$150 price range it looks like you can get one of these, or if you step down to a 500 series you are looking at 550 Ti / 560 for that price, so it seems like the 600 series is a much better buy.

Comments?
 
In games the 650Ti is about as fast as a 460. I would imagine PPD would be similiar to a 460. So maybe 10k PPD........just a guess.
 
Not much because PG will use gtx460 or gtx560 as their metric. You need a faster card than that in order to get any bonus.

This statement has absolutely no basis in fact.

Initial beta tests peg PPD on a P8057 at around 50-60k PPD for a card of this caliber.
 
Well, you are both right, with the 8057 they raised the base points a whole bunch also, not just the bonus points.
 
Yeah, my post sounds kinda harsh. Not my intent. Sorry!

I did not mean to intone that vincel is wrong - just that he is being speculative and that what little preliminary information we have to go on at this time would indicate otherwise for a GTX 650Ti.
 
I would guess much higher than 10K ppd. I believe FAH is sensitive to the number and speed of shaders. My 560Ti has 384 shaders @1760 MHz and is getting 18-19K ppd. My 550Ti was getting 9-10K ppd before I put it in my teens machine sans folding. The vanilla 650 also has 384 shaders and the 650Ti is listed with 768 but the shaders speeds match the cores now on the 6xx series so the shader increase will be mitigated somewhat. Should easily match or beat most quad CPU's on smp though ;)
 
as of right now with the current WU's they are more clock sensitive vs shader count sensitive. but thats probably going to change here in a bit so i'd honestly hold off buying any low end card specifically for folding until the QRB WU's are finalized. because we could end up having another GTS 450 fiasco where the GTS 450's were making upwards of 10-11k PPD then a month later PG released a bunch of new WU's and retired the old ones dropping them down to 7-8k PPD.
 
Yeah, I think I'll hold off for now. Not a big deal as prices will only go down, heh.
 
I have two GTX 650 Tis coming in. I plan to put one in a dedicated sempron box, and the other will go into an older quad core. If the sempron box can't feed the card, I'll move it to a newer quad core. I'll post what I find.

I picked the card mostly because of the price ($139) for 768 CUDA cores fit into my budget better than a single GTX 660 Ti. I'm mostly interested in folding while the weather is cold and Anandtech's folding benchmark basically had the 650 Ti at about 70% of the folding performance offered by the 660's 960 CUDA cores.

Plus, I'm getting two free copies of Assassin's Creed! (cheap x-mas gifts for close friends).
 
I just received my GTX 660 ti and it had 1344 cuda core not 960 priced at $239/
Have to see what it will do:D
 
Oops, my bad.

The GTX 660 has 960 cores while the GTX 660 Ti has 1344 cores. 8)

I'm really just heating the house over the winter for now and trying to dig myself up from #1090 on the team while having fun and learning. :)

My kind of approach
 
I'm getting 83K PPD on 8057s with my GTX 650 Ti @ 1100 core

TPF = 2:45

Your post kind of made my day. How did you OC the card? I might run stock when my cards come in since I live in Hawaii but even here the winters can be colder depending on where you live.

I have 4 650Ti's shipping. I'm going to put 1 in a PCIe V1 Sempron Box, another in a AMD quad 635 box, and 1 in a 8-core (Zambrezi @ 3.6GHz) - maybe two if it works out, if not, the remaining 650Ti will go into a newer AMD quad desktop box.

I don't really game much and was drawn to the 768 Kepler cores and low power-requirements for the card.

I'll post up FU info on the cards as I get them in.
 
@Dookey
Any advice on mem clock and voltage?

Thanks again,

Thanks!, I played around and did the same. My EVGA card is stable with +200MHz OC on the memory with the GPU at 1050, but my TPF didn't decrease, so I left it stock along with the voltage.

I stopped trying to use core 2.22 on Kepler since it seemed like it lowered PPD performance and was a hassle to backload.

At stock settings, the worst 8057 unit reported 47K ppd with a TPF of 3:13 , and the best unit reported 70K with a TPF of 3:04 with the GPU @1050.

I'll try to take more notes on the 8054s and post up as I learn more.

8054s seem to give about 11.5k PPD with a 3:03 TPF @1050 GPU.

FWIW, Kepler requires core 2.25 in order to work. It is only the Fermis that you can switch back to 2.22 for points gain and even then there are some WU, like 76xx, that require 2.25 even on Fermi.
 
I have 3 EVGA GTX 650 Tis running right now and they are all stable at 1097MHz with stock memory and voltages. They all run in about the 68-71C range give or take depending on ambient temps. (mid 70s to high 60s F).

Seeing the following PPD:
WU=7625 PPD=7.5K TPF=09:54 (Sempron)
WU=7624 PPD=7.8K TPF=09:33 (Quad AMD)
WU=7626 PPD=6.8K TPF=10:58 (Eight-core AMD)
WU=8054 PPD=10.1K TPF=3:23 (Sempron w/GPU at stock settings)
WU=8057 PPD=71.4K TPF 3:04 (Quad AMD)

Meanwhile on my 8-core machine [email protected], I'm only getting:
WU=7647 PPD=8.3K TPF=23:06.

CPU folding Quad [email protected]:
WU=7646 PPD=3.1K TPF 48:02

The nice thing about the cards is I'm running one of them on a Sempron with a 400w PSU that just happens to have native the 6-pin PCIe power connector. I'm tempted to craigslist some couple or so boxes to host a spare card as I upgrade 1 card (for gaming) to a GTX 660Ti.
 
I have a hard-on for this card. Stable at 1100 w/o voltage bumping and running two of them on cheap 400w PSUs.

Seeing:
WU=8073 3874 points Base&Expected, 18,804 PPD, TPF 2:58
WU=8074 3474 points Base&Expected, 18,910 PPD, TPF 2:57
 
wurmy, Interesting... You are getting almost exactly the same TPF's as my laptop with a 680m. 1344 shaders, but only ~850mhz.

And wow, that bulldozer machine is surprisingly slow! I am seeing the following: (CPU Folding)
3930k @ 4.8Ghz 6-core
7647 - 6:46

i7 980 @ 4.2Ghz 6-core
7647 - 9:21
7646 - 9:17

i7 920 @ 4.0Ghz 4-core
7646 - 18:08

That laptop you have is a stud. I wish we could get more of that efficiency from our desktops.

The GTX 650Tis have 768 kepler cores. Instead of trying to measure the pull from the outlet by buying a kill-a-watt, I threw away my ATi 4850 and ordered another GTX 650Ti.

The Bulldozers suck at folding and I assume that Piledrivers will be in the same boat based on reviews. Because the CPU doesn't produce, I "saved" money by buying another GPU instead of a $70 HSF unit w/a back plate. As it is with the stock cooler, I have to underclock it by 10% until the weather cools down more.

Despite my personal Bulldozer fiasco, I stuck with AMD quads as they were cheap as CPU/mobo combos to host GPUs. Even with the 8057s gone, I have a feeling that Kepler GPUs are the way to go, even for everyday use.

I'll buy myself a kill-a-watt for x-mas and can check how much the cards pull, but like I said, I'm running a couple of them with the "400w" power-supplies that come with cheap cases.

...and that's a STUD laptop. The last time I had something that hot on my lap, I was in downtown Las Vegas!
 
Please grab a PSU deal on newegg soon.

One of the Earthwatts or Corsair.

The died in the line of duty thread it littered with hardware that was killed when a cheap PSU gave up and shocked the crap out of stuff when it went.
 
I would highly suggest the Rosewill Capstone 450's. They are 80+ Gold and actually very nice PSU's and usually about $59 or so. I am using a few in some of my server boxes. They have gotten good marks on reviews, and they are built using a platform from a pretty reputable OEM.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182066

I would take this over any antec and most corsairs even!


And yeah, this laptop rocks, heh. :D

ball bearing or sleeve bearing fan ?

Yeah and how long is the warranty?? As Kendrak said there are posts and more posts with crappy PSU's - hell there is even one going on at the moment where it looks like a 1200w unit can't supply a 4p system due to its crappy design.

Corsair may not be the absolute best - but for 99.9% of users they are and if it does go wrong, RMA is easy
 
5 year warranty, and it's through Rosewill who is essentially newegg and I have always had good luck with them. Seriously, that 450w capstone is better than any corsair you can get for the same price. You would be looking at a very old design 80+ bronze corsair at that price.

It is a ball bearing fan. http://www.anandtech.com/show/5698/rosewill-capstone-450w-and-650w-80plus-gold

They actually test pretty close to 80+ Platinum, which is basically amazing for that price.

Here is a Johhny Guru review of the oem version of the same PSU: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=250 (450W Super Flower Golden Green Pro) it gets an 8.8/10.

Johhny Guru said:
What Superflower has here just so happens to be one of the best smaller units I've tested. The Golden Green 450W is efficient, quiet, and it regulates as steady as Clint Eastwood's shootin' arm. It's just about the best option that I can think of for general purpose light duty rigs with one video card. Bust out the wallet and grab one, says I.

Damned [H]ard info!

I have a Rosewill stallion 450w PSU, and an older Rosewill 650w PSU (new) as spares, but I'm going to listen to you experts and change out the cheap PSUs before I need to make a "died in the line of duty" type post. (fingers crossed)

You want to know something funny, my GTS 450 averages about ~10 PPD and at the moment it's folding an 8000-series WU @ 15K PPD. Even though I receive the occasional WU that drops the 450's performance to around 7K, they are not that common. Mind you the card is OCed substantially.

I guess I was lucky (rare) and totally agree with your advice to at least buy a mid-range card. Nevertheless, for the investment of the time, the GTS 450 was quite a good card that continues to produce well after a couple of years. I never expected it to still average 10K PPD at the end of 2012. :cool:

The bulldozer is surprisingly hot also! I remember seeing a 12K PPD WU come in once, but I forgot to note it, but other than that, it's around 8K PPD. Which would be ok w/me until...

...I added a 2nd GTX 650 Ti to the rig and put an house fan on near it, the box still ran hot, so I underclocked the CPU by 15% w/stock v, but the box wasn't stable. I was hitting 65C on/the CPU even underclocked, so I ended up deleting the CPU slot from the client.

I might try disabling half of the cores and seeing if I get MORE than half of the performance, or at least get stable temps from the CPU w/stock cooling setup. I'm waiting until two good GPU WUs finish before I make any changes.

It's an unlocked FX 8150, and while I should buy a backplate HSF for it, I have a gut feeling that it's not going to help much at folding. I was kinda drunk, but read somewhere that there are only 4 ALUs shared among the 8 cores, but when I bought it, I was VERY drunk, and 8 cores looked good to me! (plus, it was cheap)
 
yeah bulldozers share the FPU among 2 cores. 2 cores which have 2 integer units and 1 FP make up a "module" so an 8-core bd is 4-modules.

I am surprised it is unstable at stock settings, even pegged out at 100% it a should be fine at stock, maybe there is something else bad like ram..?
