Folding on AMD GPUs

[Rattledagger]

OK, the 7950@$400 get 80k ppd, and my GTX780@$500 get 160kppd. How is the 7950 the winner PPD/$ ? or am I missing something.

Well, taking a look on the prices around here, the 7950 is so old it's not even being sold any longer, but the 7970 is sold for $405 while the cheapest GTX780 is sold for $664. Since the 7970 is 25% faster than 7950 it should get 100k PPD, meaning Amd gets 247 PPD/$ while the GTX gets 241 PPD/$.

BTW, since FAH is still adding new Core-15 projects, if you've not got the time (and inclination) to get crunching under Linux to work, the Nvidia can as average have significantly lower PPD/$.

Edit - I forgot one thing, since FAH's point-system is FUBAR a 25% faster Amd-GPU will get even higher PPD/$ so maybe around 260 PPD/$ will be more correct.

in all fairness, theAnimal posted that info 3 months ago now, just as AMD GPU prices started to skyrocket due to the GPU mining craze. if the average price of a 7950 was say ~$250 back then, then that puts the 7950 on equal footing w/ the GTX 780 as far as PPD/$ is concerned, w/ the slight advantage to the 7950 if you consider that the GTX 780 consumes more power than the 7950. and if you consider that the average price i paid for each of my 7970s was $225, and that i get 95K PPD out of just one of them while Folding, that's a substantial PPD/$ advantage over the GTX 780...of course by today's AMD GPU pricing however, you'd be right in saying that the GTX 780 has the substantial PPD/$ advantage over either the 7950 or the 7970.

Thanks ! I really wasn't trying to be adversarial, something just didn't look right. The other thing for me, is when you put 2 cards in a box, the cooling of one suffers (unless they are really far apart) I burned out 6 460 cards, and 2 560ti cards (the fans) from them running so hot. Now as I rebuild the farm, I just put one 780 in, and I am done. And actually less power for one 780 then 2 560ti cards.

As for the post above me, I am just looking at newegg, and my 780 is $509. and the 7970's are $450.

Cheapest 7970 I could find: http://www.newegg.com/Product/Produc...82E16814129204

My 780: http://www.newegg.com/Product/Produc...82E16814125488 (actually $500 after rebate)

GTX780 is sold for $664

Seems obvious Rattledagger meant GTX780 Ti price?

No TI's that I can find are under $700. not sure.

Hmm ... give me 30 seconds, there we go ... $670 AR

These prices can change in a few minutes.

Hmm, is where different kinds of GTX780...

Taking a look, the cheapest GTX780 Ti is at... $842, due to currently being 9% cheaper than normal. The majority is around $970.

As for the post above me, I am just looking at newegg, and my 780 is $509. and the 7970's are $450.

It's surprising that anything is cheaper over here than in USA.

Woa, those prices are way different. Where are you located ? I think this discussion needs to be location based, as that could be a different answer in different parts of the world.

Norway, as a comparison unleaded gasoline costs 2.48$/L while diesel is a little cheaper at 2.32$/L.

Not sure if comparing against 7970 is the best since only 2 different cards is available. Better would be the R9-290X, these starts at the same prize as the GTX-780 around here.

Glad to hear that F@H is finally about to bring ATI/AMD cards upto speed.
Btw what's your suedo 6970 ppd on non core 17 WUs? 20k or did that include core 17s?

The performance on non-core17 WUs is still as pathetic as it has always been (my pseudo 6970 gets around 5 or 6K on anything but core 17 -- which is a complete waste and not worth folding on AMD when other projects could use the hardware & power more efficiently).

On the upside, as far as I can see, even the latest, greatest NV cards perform better under OpenCL mode, which should mean that the good F@H people are most likely only using that going forward. So there shouldn't be the huge disparity between brands, going forward.

OK, the 7950@$400 get 80k ppd, and my GTX780@$500 get 160kppd. How is the 7950 the winner PPD/$ ? or am I missing something.

I think Sunny129 already cleared this up, but yeah... I bought both my 7950s new for something like $250 & $260 nearly 1.5 years ago. Mining last winter paid them off and them some (bought myself a really nice leather bike saddle with the profits). And during the 2013 holiday race each card was pulling down 100K PPD... It has just been an exceptional cycle, pricing-wise, with the 2013/2014 mining madness making nearly 2 year-old cards cost more today than shortly after their release.

that's exactly why i buy mobos w/ 4 PCIe x16 slots for my multi-GPU (specifically dual-GPU) machines - so that the 2 GPUs in each machine have 2 slots worth of space between them. that's particularly necessary when your GPUs use dual or triple fan coolers instead of reference-style blowers.

:thumbsup: , glad I'm not folding with my 5850 then .

And that's bonkers with the 7950 prices!

So have core 17 WUs become the sole work now or is the old core 15 still in action?

Plimogz
Sorry I didn't clarify, so was the 20k ppd on your '6970' core 17 WUs only?
If so that seems to contradict theAnimal's opening post about 69xx being ppd leaders (along with 79xx GPUs) on core 17

Looking at the benchmark thread I linked the 79xxs are doing very well (in the top 10-15), however their isn't a single benchmark for 69xxs!
Could you run the benchmark on your suedo 6970?

I'm going to run it on my 5850 to add an ATI benchmark .

for the december race my 5850 was around 12k ppd while my 7950 was 90k ppd both at stock speeds and core 17s.

Interesting. According to the F@H Control applet that comes with it, I was getting 36-37K PPD for each of my 7790 1GB GDDR5 cards.

 

[Assimilator1]

Yea especially considering the 5850s SP power is ~16% faster than the 7790s

Anyone know what's going on?

Btw Larry, don't fancy posting WU times in my MW bench stats thread?

 

[Plimogz]

I have just noticed a nice increase in PPD from my 7950s, due to a change in WUs, apparently:

The points have gone from around 180K/day (90K-ish per card) to 240K/day, and the only thing which seems in any other way different is that the WU's PRCG (?) is now 13000 instead of 8900 -- otherwise, these are still FahCore 0x17.

Anybody else notice an uptick in GPU PPD?

NVM, looking at it better now, it appears to have been just a poor PPD extrapolation on the part of the fah client.
