GTX1070 x 1080 x 1080TI - which one with the best ROI?

[fcaldas]

The only cards available with my shop right now are:

MSI Geforce GTX 1070 Quick Silver 8G OC
EVGA GeForce GTX 1070 FTW GAMING ACX 3.0
MSI GTX 1070 ARMOR 8G

I believe the best one is the EVGA, but the max power draw is 215W, so that's way too much.

I thinking of the MSI Armor one, simply because it's 50 dollars cheaper than the other MSI.

Anyone have any opinions on those cards?

Thanks

Nvidia cards work well with a TDP of 60% - 70% without a noticeable drop in hash. You can lower the TDP on Nvidia cards using MSI Afterburner or EVGA precision. The MSI Armor series are the the basic no-frills pieces from MSI. No backplate, aluminum heat pipes, open frame dual-fan design and they run hotter than other cards. I would go with the cheaper one between the other two cards, they are about the same.

go with the ftw they are unbelievable i have one rig at 50 percent tdp, neg 200 core , plus 600 mem doing 29.8 eth
on all cards at a total system wattage for 730, on 240v that would be like 90w per card, dual mining same settings 28
msh and 350 sia 850 watts.

crazy cards , in comparison 480 rig does 900 watt and 1100 watt respectively

Hey, are you using 8+6 pin connectors or just 8? Thanks!

As I was writing in another thread, the shortest ROI can be achieved with 1080's. The 1080Ti will hash ~25% faster but costs 40% more.

Just don't mine ETH. Mine Skein or LBRY or Equihash, whatever works best at that point in time.

what would you reccomend

for dual mining

Vann: That dropped my temp immediately and basically getting just a little bit less Sol/s. Amazing what 5 seconds of tweaking does.

Yes, and the 20-30% in power you save will also offset the small hash drop by far.

can u show ur value's proof? is there any link?

good video, thanks for posting, especially the specific part you were talking about. it would be hard to find it in 3 hours of video

I am almost sold on the EVGA... better heatsink (compared to the other two MSIs I have access) and I just think the resale value will be better.
I am just concerned with the 8+6 pins setup.

My plan is to buy a Corsair CP-9020100-AU AX1500i 1500W. Shouldn't this be enough for 6 1070?

Thanks yall

For 6 x 1070 you need a good 1200 Watt PSU.
The Corsair is fine, i have some. A bit expensive, but very good.

Thanks! Indeed a bit expensive, but I think it's worth the investment.
Cheers.

...and even (slightly) faster with 5x 1080. And you'd still have slots available to add cards to your rig at a later stage.

And for about the cost of two more 1080 Ti's you could build a second 1060 rig with six cards, another motherboard, PSU etc, have more hash, more options to mine and a faster ROI than adding two 1080 Ti cards. An eight card 1070 rig would also give you the same hash on Equihash than five 1080Ti's and 65 H/s more on ETH for about $500 less. That's why I said the only reason to buy a 1080 Ti is if you want to maximize the total hash for a couple of rigs and don't care about the cost of the cards.

You keep bringing the Ti, I'm talking about the "regular" 1080. 41% cheaper and only 25% slower.

[fcaldas]

Well, this is very effed up! I had to go with 6  1060! I could not find a single 1070 available anymore!!!
Oh well, guess ill start from there and upgrade every time I see one available new card...

Thanks everyone!

Not true at all.  The hash per cost efficiency of a 1060 is much better than a 1080 Ti. At 60% TDP the GTX 1060 3GB cards do 260 H/s on Equihash using 60 W each and only need a single 8-pin connector. At a cost of $200 each that's 0.77 cents per hash. On Equihash the 1080 Ti does 750 H/s at 250W and at $700 each, that's 0.93 cents per hash. Three 1060 3GB cards would do 810 H/s using 180W, outperforming and costing less than a single $700 1080 Ti. With the three 1060's you also have the option of mining ETH at 65 MH/s for 3 cards vs 37 MH/s for a 1080 Ti.

 1080 ti doesn't need to run at 100% TDP to achieve 700+ sol/s.

 For perspective, my NON-OPTIMISED EVGA GTX 1070 SC (or my Gigabyes that factory-clock and factory-TDP higher but I have to set the TDP % lower) with nothing more than a drop in Afterburner to 80% (65%) TDP pull right around 400 sol/s at about 120 watts - and also only need a single 8-pin connector. I'm 100% certain I could do quite a bit better if I optimised them, but I usually run Skein when I crypto mine on them at all (and the optimisation for the other stuff they USUALLY run doesn't like very-low TDP).

 Folks that HAVE optimised their 1070 and 1080 cards routinely post pics showing better than 4 sol/s per watt (VERY close on efficiency to what you cite for your 1060 models), leading to a lot better density - and when you factor in TOTAL SYSTEM COST they're pretty close as well on a hash/$ basis.

 
 NewEgg still has some 1070 models listed - but the price HAS been climbing the last couple weeks, probably as a response to the AMD RX 470/570/480/580 shortage driving ETH miners into buying Nvidia cards to keep growing their farms.
 It's also possible that whatever NVidia is "stocking up for" on a new card (as reported in their last earnings call) might be impacting their production of the current lineup - they HAVE been rumoured to have a next-gen upgrade to the 10xx series in the works for a while, probably similar to what AMD did on the RX 4xx to RX 5xx small upgrade....



 I've never seen nor do I see any reason a GTX 1070 would need 2 PCI-E power connectors - even my Gigabyte high-end cards only have a 180 watt TDP, a single PCI-E 8-pin + the power draw from the PCI-E bus is specified to handle a 225 watt draw.
 I COULD see the faint possibility of a high-factor-overclock GTX 1080 going with a 2-connector setup - but have never seen one yet.

No contest the 1070 is easily the best hash/cost all around performer from Nvidia GTX 10 series GPU's, especially on ETH.

108ti - 37 MH/s
1070 - 31-32 MH/s
1080 - 25 MH/s
1060 - 22 -23 MH/s.

The only reason to buy a 1080ti is if you want to maximize the total hash from a couple of rigs and don't care what you pay per GPU.

lol on ETH yes, but you don't mine ETH with nvidia, you mine zen or zcash or zcashclassic or lbry, and the 1080ti is very good there 60-70% faster than a 1070, 1060 is abd overall bad density very low ahshrate, bad efficiency

yeah but the 1080ti beat them all on skein algo, with 90% more hash than a 1070, and also on x17 is very good with 80%+, it depend on the algo, on equihash it's not that bad, i prefer it for the density over the 1080
