Topic: 3x 1080ti or 5x 1070ti? (Read 361 times)

Given that the EVGA G2 850 watt PS can still be found, sometimes at a REASONABLE price, and the power connection limitations on it, I've been thinking I may end up going with a mix - 2 x 1080 ti, 2 x 1070 ti - at some point on my "6 amp rigs".

 Won't be soon though, as I still have several "ex-folding" rigs left with Seasonic X-850 or SS-860 power supplies to "convert" to riser rigs.

I`ve recently had the very same dillemma and opted for 3x1080ti. Better profit in most nvidia friendly algos, better resale value, less space, space for adding more cards later (if you buy 6 pci slot mobo right away), less power draw, etc...

With two rigs you don't have a problem with space so 5x1070 rig is ok.
Both of them are good. Price is here a big factor.

 Should manage it at 60% - and you don't get 4.4+ out of a 1070 ti at much more than 60% so it works out.
 50% in MY testing on 3 different 1080 ti cards was a hair WORSE efficiency than 60%.


 Any suggestion of mining ETH on a NVidia card OTHER THAN a 1060 model is dumb - 1070 and up will earn a LOT more on many other coins than ETH.
 The ONLY reason the 1070 ever got popular on ETH was when AMD comparable-hash cards got up into the same price range as the 1070, and ended up pushing IT'S price at the peak up well into the 1080 range.

Go with 1070Ti as it has GDDR5 and you can easy overclock memory to gain better performance in case you're planning to mine Ethereum

I don't get to 4.1-4.2 unless I drop TDP down to 50%

i still have my 280x..it's mining for 4years already.....if there is a card that I will use for a long time it is 1080ti

back then 280x vs 290/290x performance and efficiency ratio is not that great, that's why 280x is the king at that time..

if 1070ti today is the 280x of 2013-2014..then it is the winner if not...1080ti it is...

i have a bunch of 280x and they are waiting for 2080ti to retire since a 1080ti equihash is just a little bit over x2 of that 280x...not that tempting, if volta delivers x3 of 280x hash, that's too tempting to replace those old gpus.

 1080 ti run at efficient settings will manage closer to 4.1-4.2 range - which still isn't a match for the 1070 ti but it's not WAY far off like you're claiming.

I used ccminer and tried to mine with algorithm lbry and the gtx 1070 ti and it crashed the PC every time. It might have just been version of ccminer 2.2.2-tpruvot I was using.
When I had one gtx 1070 ti with a bunch of gtx 1080, it did not crash. It might also be because I was overclocked too, but seems okay on other algorithms. I am sure it is fixable though.

Everyone is going to be different - if you have space issues, then 1080 Ti will be for you, if you have Amperage max out issues, then max efficiency will be for you.

For me personally I will be moving to 70 Ti's for the (approx) 4.5 Sol/W vs 3.2-3.5 Sol/W, per 10kW draw that means 10-13,000 more Sols - That's nothing to sneeze at.

Everyone will be different though.

I keep seeing people say this and it's just not true - the highest end graphics cards plummet the most in value over time; it is the midrange cards that tend to hold their value better. The reason is that the top of line cards are grossly overpriced relative to their performance (in FPS *or* MH/s) while the midrange cards tend to offer the best performance for the money. The low end is a lot like the high end, in that you grossly overpay for the performance delivered, except this time the performance sucks.

EDIT - prices for previous generation top of the line cards are higher than normal because they are still usable in mining - a $530 GTX 980 is still selling for about $320 on ebay - but if the bottom drops out of crypto then those same cards will, indeed, plummet in price. That is normal market behavior for PC components; even my AMD FX-8300 took a severe haircut after Ryzen came out...

1080ti has more resell value and if you ever decide to stop mining you can build yourself a superb SLI gaming rig, and a pc dedicated for streaming, and be a pro gamer/streamer

I like the 1080ti for rig density as I don’t have unlimited space

 For the EVGA G2/P2/T2 line this ends up being an ISSUE as they only have 4 connections for VGA cables, and their "dual" cables are always 8+6 - so the G2/P2 850 definitely prefers the 3 x 1080 ti setup as it has the right cabling out of the box to support that.
 The G2/P2 850 also has a shortage on available connections to power risers with for a 5 card rig.

 The EVGA G2L line is an odd duck with it's "universal" connectors, I believe a G2L 850 it would work either way - but I got shorted on power cables on the only one I have so I'm not SURE on that.

 For Seasonic X-850 or SS-860, not an issue either way - more VGA cable and connections available, AND more "peripheral" connections to power risers.

 If you are going to push the cards well past their more efficient point, you have to go to at least a 1000 watt PS and the connections issues no longer matters at all.

 IF you set them for the same power usage, the 1070 ti cards will provide more hashrate (on ZEC anyway, haven't played with the 1070 ti at all on anything else but ETH which is a BAD choice) - tradeoff is the "more cards to manage/space taken" question, and it's pretty close either way.

 Neither option is a BAD option, it's more about personal preference on "rig density" vs "best hash/$ + hash/watt" and the efficiency isn't majorly different either way.

so, with 1070ti you can gain more hashrate than the big brother one with different algos?

Hi, I have 5x GTX1080ti  and 2 x gtx1070ti
my 1080ti cost me like 700$ and 1070ti about 450$ - so it is about 55% diff
but if we see the performance wise - the big brother will be faster about 35-45%, in some algos even less
for example eqiuhash - 1080ti push - 770 sol/s, while 1070ti can make 535 sol/s - that is about 43%, but neoscrypt it would be 1660 / 1350 kh/s - 22% only
so most of the time 1070 will be more balanced. but if you need true power - take big brother!

3x 1080ti's will b easier to run on a single PSU for cabling, and it is less GPU's to trouble shoot if one of them is overclocked too high and causing crashes after 6 hours. I'm in the minority who prefers to run more powerful cards over quantity and for what its worth more quantity per rig pulls in a greater ROI

As title, which is best. My current rig is basic;
2x 1070
2x 1060 6GB
1x 1080
Some motherboard with 13 pcie slots.
850W EVGA PSU.
850W Cheapo PSU for 1080.

I want to expand and add another EVGA PSU and either
3x 1080ti @£680 = £2040
or
5x 1070ti @£420 = £2100

Has anyone trialled both, which is best!?

Thanks.
