let me know what you find.

do you have one 780 or two?

I have one installed, one sitting in a box. I purchased it with the expectation of a CUDA primecoin miner, which never really happened. So I left the card in-box, waiting for either CureCoin's public release if it turns out to be really profitable, or to sell it on ebay and get my money back. Personally, I find ATi systems seem to give better PPDPD, but worse density. I have some of my scrypt machines (the rest are waiting on wifi cards, I can't for the life of me find where I put my spare pci-e wifi cards, but they're only $10/pop, so I ordered some more) pointed, and the 7950, which is around $270 now, hits a good 80,000 PPD, while my 780 hits a solid 110,000, at a price of $660. However, the nvidia card uses less power. Figures. Smiley

Oh, cost estimate stuff is in the post above, I did a quick edit Smiley

Were going fast towards rank 1200, looks like Vorksholk will be getting my bounty, unless someone can beat 538,597 PPD!

im doing my best to catch up Smiley

How did the Titan overclock? Smiley

well im maxing out at 1110mhz. pulling around 153000 points now.... lol

That's pretty nice Cheesy I wish they were just a bit cheaper so that the performance would line up with the 780s... I would finally have an excuse to get one xD

i MAY go pick up one more. id really like to be top of the board. lol

The titans are great if you have just a few PCI-e slots and want to make the most of them, however if you're just going for PPD per dollar, then you might want to consider the 780s. (Although the titans are more well-geared towards 24/7 computation).

yeah i thought about the 780, but i really wanted top performance. and since i already have one, i could get another and SLI them. and just turn off SLI when i want to fold.

True Smiley Also, titan will probably hold resale value a tad bit better. I'm gonna go see which is more profitable considering the titan's higher density.

EDIT: For people looking into building a high-end folding machine, a 3x titan machine would cost $3626 a pop (with a platinum PSU, 4-core processor (need), 4GB RAM, etc), and would produce around 420000 PPD (Wow!).

A 3x780 machine would cost a more modest $2640.18, while producing around 330000PPD. So, the 780 machine would achieve around 125 PPDPD (Points Per Day Per Dollar), while the titan machine would clock in at 115.83 PPDPD. Close enough to make titans possibly worthwhile, either for space efficiency, slight energy efficiency bonuses, or the higher resale value of components.

If you decided to go extreme and do a 4-GPU system, however....:
4x780 build (80+Gold PSU, 4GB RAM, 4-core Vishera cpu, etc.): ~$3,600.
4xTitan build: (same as above): $4905.90

With that in mind....
4x780 will achieve around 440,000 PPD, while 4xTitan will achieve around 560,000 (WOW) PPD.

For PPDPD values.....:
4x780: 122PPDPD
4xTitan: 114PPDPD

So, I guess 3-card and 2-card builds are likely the way to go....

I kept meaning to ask in the curecoin pool thread how your 780(s) were testing, always forgot. (did you open the 2nd one?)  Smiley

Thank you for taking the time to do all this and posting your findings. Much appreciated.


Still haven't opened the 2nd one, but it is oh so tempting, I put it out of my line of sight xD

The one 780 that I am running is doing well, it's hitting somewhere in the ballpark of 115000PPD right now, not terrible, but ATi cards seem a bit better for the price (especially 7970s).

I ordered a few more wifi cards, once they arrive I should be able to (temporarily) point another 5 or 6 7950s at folding, hoping to break the 1,000,000PPD bounty.

For anyone wondering about the appropriate hardware for Folding@Home to maximize their PPD, go as high-end with cards as you can. The way the bonus points system works, even if two 660s can fold just as fast as one 680, the 680 will get you significantly more points. Here's why:

The bonus points model is based on how quickly you return the work unit, following this exact formula: PPD = base_points * max(1, sqrt( k * deadline_length / elapsed_time)) where k = 0.75

The idea is that you get a work unit, say a project 7810. Each project has a different amount of computations, and a certain guaranteed credit. For a project 7810 workunit, the base credit is 3076. As long as you solve that workunit (and of course upload it!) in the alotted time, you are guaranteed that many points. However, as the formula above shows, you get significan extra credit for submitting early. As an example on a 780, that 7810 workunit would be worth around 14500 points, which is 4.71 times the base credit.

Given this logic, it'd be (in terms of PPD), more beneficial to finish one workunit fast, than to finish four of them slowly.

A Bit of math to back this up:      
Project: 7811 Using calculator: http://www.linuxforge.net/bonuscalc2.php

TPF: 1 min 20 sec <-----NVidia 780
TPF: 2 min 40 sec <-----NVidia 760 (estimate)

The 780 would get 11292.67 points for each job, while the 760 would get 7985.03 points for each job.
While the 780 and the 2x760 builds would each get approximately equal numbers of jobs done per 24hr period, the 2x760 build would be at a disadvantage, making less PPD per kWh (2x760 and 1x780 use approximately equal power, 2x760 will be slightly higher due to having to run two sets of fans and other components that aren't duplicated when moving to a 780, however the main power draw is the cores and memory anyhow).

The machines with PPD compared:

780: PPD: 121960.8
2x760: PPD: 86239.34

However, it's important to note that 2x760 costs $520, while one 780 would cost $660.

This compared, the 780 gets 184.798 points per dollar per day (PPDPD?), while the 760s get 165.84489 PPDPD. As well, the 760s take up two slots, and consume slightly more power.

Higher-end cards are a given until you reach the Titan, at which ~140,000 PPD @ $1,000 is clearly not comprable to the 780.

You can see a similar relationship between ATi cards, a 7970 gets around 120000PPD, a 7950 hits around 80-90,000 PPD, and a 7850 gets in the 35,000 ballpark.

Of course, if you only want to buy a cheap GPU and fold a bit, there's nothing wrong with the lower-density, cheaper cards, which are great for entry-level builds. However, even if two 760s is the same power for less price, due to the bonus strategy, the 780 will produce higher yield PPDPD, at less electricity, with more room for additional components. As well, overclocks are very helpful, earning more of those sweet, sweet bonus points.

Not sure if doing it right.

As long as you have a pool account at http://75.134.182.16:10506/ under the same name, you should be good to go!! Smiley

952  Alternate cryptocurrencies / Altcoin Discussion / Re: WHICH Processors Will Mine PRIME Coins FASTER?? INTEL OR AMD on: August 06, 2013, 03:51:49 PM

For the record, that's an increase of one core of a 6990 over one core of a phenom processor, so the true ratio is only around 3-4x increase, and so far that's only for the sieving process. Sad

7810




Hmm. interesting. 140000 sounds about right, as the 780 has 12 SMX's while the titan has 14, my 780 is getting ~110000 PPD, 140,000 sounds about right when thinking about the gpu's architecture. Do you have any overclocks on that titan? Smiley

ok thats cool. im just about to try overclocking it a bit actually!

hey do you know if turning on double precision would speed up folding? or slow it down?

Double precision *should* be slower. I would stick with single if I were you, but if you do switch it over I'd be interested to know what you find.

ok got it. im chugging away! you should see me pop up soon. coconutboy84

Awesome, how many PPD is your GTX Titan reporting?

its weird, right now. 284847 but then it drops down to 140000 ish.

Hmm.... what number work unit did it get?

im a total noob with this but i have been an avid folder for like 6 years. how can i help?


Hey keenan84, glad you're interested! I put together a short guide that probably is quite redundant for a folder like yourself, but it also has info on how to join the pool, and make a bit of cash for your folding. Smiley

melnikalex seems to be in the lead for the big dgc bounty, still anyones game if someone with a large mining setup went for the bounty.

Hmm, that'd about cover electricity plus a tad bit of icing. Smiley

I didnt put it in the shortcut before. I was able to get it to 43k for the card by using an older graphics driver - 311 instead of 320. It just seems low since I'm getting 38k with the cpu.

Wow, what CPU are you crunching on? Cheesy
