Topic: GTX1070 x 1080 x 1080TI - which one with the best ROI? (Read 3233 times)

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

 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.

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!

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

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

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

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 dual mining

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

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

But do I really need to use the 8+6 pins connector? The RX570 had 8+6 but it could go by with just 8.
Let me double check if these three cards have 8+6 connectors.

Ps: I am loving how my little topic created so much discussion

EDIT:
The MSI GTX 1070 ARMOR 8G in my shop has the following config: Just 8 pins. So I am tempted to go with that one, unless I can find someone to confirm that I can use the EVGA with just 8 pins.

None of theese cards are a good option for mining. EVGA FTW and Quicksliver cards need 8+6pin so you will have a cable fuckup and large additional costs with PSU.

Your best option is the MSI GTx 1070 ARMOR 8G - but those are not in the production anymore, so you are most probably talking about MSI GTx 1070 ARMOR 8G OC version, which again has 8+6 pin of power needed.

If you really want to buy those cards then you will have to go for Dual PSU overkill to have enough cables.

In this situation I would try to analyze if it is not more worth it going other options such as the 1060.

I would recommend the 1080 only to those that have very good knowledge of algos and coins and can make use of that card to its fullest.

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

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

You can adjust it with the power limit slider.

How do you drop the TDP in afterburner?

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.

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

You can easily run nine 1060's off a single 1000W PSU at 60 - 70% TDP and 2-3 cards per PCI-E cable on ethOS, smOS or Linux. Add a $160 Asus Z270-AR/ A board, two $5 M.2 to PCI-E adapters and for less than $2500, the rig would give you 2300 H/s for nine cards on Equihash and 207 MH/s on ETH. To get the same amount of hash on Equihash from a 1080 Ti, you would need three cards for at least $2100 just in cards and still need a 1000W PSU, mobo and cpu. The only other added cost for 1060 rig would be more risers and you would make your ROI faster with the nine card 1060 rig.
