title is self explanatory.

whats the best bang for buck (in terms of RAC/$) of cards available in 2018.

1080's and 1080tis are top producers of raw power, but what about how that power scales for what the card gives in terms of RAC?

if you were to build a multi-GPU rig for max RAC on minimum dollar, what would you choose?

doesnt have to be brand new cards, 700/900 series nvidia cards are on the table since prices of these are very reasonable compared to 10 series due to the mining boom, but prices are starting to come down on the used market.

980Tis are slightly slower than 1080s. But use more electricity. Depending on your electric cost, might be something to look at. Brand new cards are going to cost $$$. Good luck

You can start with Shaggie76's often updated chart of GPU FLOPS: Theory vs Reality

Shows that the best bang for the buck gpu is probably the GTX 1060. But that was at its original MSRP price and not the current inflated prices caused by mining and RAM shortages.

You won't likely find the 1060 used as a castoff from mining because it was perceived as a mining underperformer. A good used and reasonably priced 980 would be a good choice also.

Could be interesting if you could run a scan with the Linux boxes who runs the latests CUDA builds.

I believe that could show if the 1070 realy has one of the best price x performance x power draw with them.

Thanks guys.

You can definitely find 1060s second hand from miners. Reddit is full of them. 3GB cards will be especially plentiful now/soon, since they are getting pushed out of ETH mining due to not enough vram. I have a bunch of 1060s in my personal mining machine, they are incredibly efficient mining ETH if you get good memory.

SETI isn’t terribly dependent on VRAM right? I think my current mix of 760s and 750tis are all 2gb models. With some 1050tis with 4GB

I run a host with a 1060 with only 3 GB of Vram, running 2 WU at a time, with out any problem in S@H, but the host is mainly a office host, no heavely graphics games runs on it..
What you must not do is gamming or run any other apps who heavely use video and crunching at the same time on it, but that is not because the Vram itself, the GPU has no enought power to do both concurrently. If you try, it works but you will experience a heavy video lag on your screen.

My titan v does twice the 1080 with less power. Titan v uses about 125-145W. 1080 uses about 160W and 1080Ti uses 225W.

But does your 1080 or 1080Ti really use that much power? I've never seen any of my Nvidia cards report the full theoretical power usage of their specs while crunching.

Nvidia-smi only shows about half to 2/3's of any card's max TDP being used.

I think we all need to look at the title of the thread again....it's not what crunches the most... It's what's most cost efficient in this day of overinflated GPU prices.

I'm just as guilty in this.

Initial cost x WU/day crunched x power draw i still believe the 1060 is the winner (specialy the 3 GB model)
maybe the 1070 could follow. That's why i sugest to run the Shaggie76 test for the Linux builds too.

In production obviusly the winner is the Titan V by a far margin, but it's the winner in initial cost too.

The 1080/1080Ti/1070Ti could produce a lot more than the 1060/1070 but cost a lot more and uses more power too.

At least with the Linux CUDA90 builds.

But I guess even 40 watts over 24 hours adds up. So every little bit helps. I too think the 1060 is probably the sweet spot.

Yes, produces a lot more but cost about 2.5-3 x more. And BTW the 3GB model it's even cheaper and works perfect with the builds.

That's my guess. But to be sure only if Shaggie76 runs the test.

FYI and add more data this are my GPU's power usage

I paid $225 a year ago for my EVGA 1060 6GB.


That's my guess. But to be sure only if Shaggie76 runs the test.


The problem I believe is that Shaggie says he can't run his scan for anonymous or Linux hosts.

I think the point we were trying to get across is that you can't buy the 1060 for anywhere near the price from "a year ago" My 1060 is selling for $290 now. Blame it on the miners and RAM shortage.
