The Zotac 1070 mini runs pretty close to same temp on the 1070 model as any other 1070 I have EXCEPT the MSI Aero mini.
 The Zotac 1080 mini though runs QUITE A BIT hotter than any other 1080 model I have.

 Gigabyte ITX runs pretty cool, but it is one of the lower-clocked 1070 models out there.
 MSI Aero runs quite hot despite being low clocked - I won't be buying any more of those for any reason.

 1700 - which overclocks almost IDENTICAL to the 1700x or 1800x and can get to the SAME hashrate as a result - but I've yet to see a GOOD Ryzen-based motherboard for mining with that didn't cost way too much to date.
 1700 is also the highest Ryzen model that normally includes the HS/Fan (mid-range AMD Spire which keeps it pretty cool for air cooling even when pushing it) - everything higher you need to add a few $$ for a cooler of some sort.

 Also, for perspective - AMD FX 8xxx series monero hashrates are pretty close to Ryzen hashrates, but the CPUs themselves are a LOT less expensive, the motherboards are less expensive, a lot more CHOICES on motherboards, and the RAM is a hair less expensive.
 Higher power draw, but not by all that much.

It is possible to be profitable mining as a Nicehash buyer - but you have to watch the profitability of what you are mining pretty closely, and be VERY careful when you calculate what price you pay the market for your hashrate.

 It's usually NOT high profitable for long at a time on any given coin, as other folks see what's going on and jump on any high-profitability coin killing the profits pretty quickly, but low profits can last a good while on coins that are fairly stable or have huge tracks of hashrate....

 PCI-E 6 pin to feed the riser is best.
 Molex is tolerable, the connectors are at least rated to handle the 75 watt draw mining cards normally pull from the PCI-E bus (the connectors themselves are rated over 100 watts but the WIRING to them is usually not sized for that unless you limit to using one connector per chain).
 SATA is bad, they are only rated 45 or so watts MAX, using them is a serious risk and has a significant probability of causing overheated connector and MELT/BURN issues over time.
  There is NO way to "do it right" using SATA on risers, as there is no way to control how much power the GPU tries to pull out of the PCI-E BUS connector - dropping the TDP normally drops the draw out of the PCI-E BUS connector on the GPU, NOT the draw out of the PCI-E bus.


 I use almost all Seasonic X-Series Gold power supplies in my rigs, but I have a few with G12 Gold series on smaller machines - they are good power supplies.
 The M12 Bronze series should be comparable on reliablity (VERY good), at a small cost in efficiency.

 I would be very cautious on Corsair - they have widely variable quality between their different lines depending on who makes each line (some are Seasonic or Super Flower made and very good, some are just junk).
 I would avoid Coolermaster, can't remember ANY of their supplies being made by a GOOD manufacturer.

 Yep, that was a mistype, I meant Equihash.

 Coin didn't exist last year. Or last month. Or TODAY yet.

 No way the yield can have dropped.

 Do not confuse the coin named "Bitcoin Gold" with actual Bitcoin - they are NOT THE SAME COIN AT ALL.

 Unholy necro - you DO realize you were replying to a *4 YEAR OLD* thread that's horribly outdated?

Algorithm was announced as Ethash (same as ZEC/ZEN/etc) - so NVidia cards will have an edge at current pricing but the AMD RX 470/480/570/580 aren't going to be BAD choices, pretty close to a tossup on hash/$ at current pricing and as I recall hash/watt only favors the NVidia side a little.

 There is no way to know what the price is going to be or the total hashrate after the first few days - but I predict that total hashrate will settle in such that the profitibility ends up being very close to the same "basket" that ZEC/ZEN/ETH and such are in.

 Start of mining has been announced as 1 November - but last time I checked they still didn't have a working wallet.

The days of 2-3 month ROI are gone - that was a very short term abberation when coin prices jumped a TON but it took total hashrate a while to catch up.

 If you are looking at less than a year to achieve 100% ROI, you're doing pretty good right now (perhaps 8-10 months if you have VERY cheap electric and can afford to push your cards a bit more).


 With that said, your hashrate seems low if you're running your 1080 ti cards at 100% TDP or close - but you get better efficiency if you turn the TDP limit down.

On my one "pure" riser rig, the risers are spaced on 4" centers leaving appx. 2.5 inches (appx. 8 cm) of air gap between the cards (closer to 2" for the Aorus).

 I avoid cards with backplates, as the backplate has a noticeable negative effect on airflow to the next card (less of an issue on riser rigs though).

 There is no such thing as a "90mm" fan in common fan sizes, the sizing on common fans goes 80mm then 92mm then 120mm.

 It depends.

 If you want the highest performance and efficiency, the Bitmain Antminer S9 models - but they are widely known to have reliability issues.
 If you are more worried about reliability, the Caanan Avalon 741 has a very good track record, at the price of a little lower efficiency and lower performance than the S9.

 EBang BW.Com and Hotmine don't have as many units in the field in the hands of non-large-mines so their track record is a lot more "unknown" except for the large farms that have lots of their units.

 Innosilicon dropped out of making SHA256 miners entirely, but the ones they DID make were rock-solid reliable - it's a major bummer that they didn't move into the 14/16nm generation.

Nicehash is a legitimate service - but read up about them, they are not a traditional "pool" as such or anything close, they are more of a "hashrate marketplace" and trying to treat them as if they are a pool isn't right.

I remember some rumors about an Intel-designed SHA256 chip - but it was a few years back during the FIRST surge as I recall and it got canned due to the collapse, as I recall those rumours.

 If Intel DID decide to build one or more mining chips, they likely would build them internally and put them into some sort of "server" design for sale - though I COULD see the possibility of them design and make the chips then offer them for sale to miner makers.

 Still wouldn't be a case of them selling capacity, as such.

I'm estimating VERY late 2019 or sometime in 2020 for the first miners on a "10nm" or "7nm" node.

Since they aren't mining Bitcoin, this should be over in the altcoins section.

 RX 470 Sapphire mining cards when you can get them at 270 ballpark, running ETH.
 1070/1080/1080ti are a very close tossup running ZEC or ZEN or LYRAv2 - and this calculation is close enough to change daily or even hourly.

 The "basket of profitable mining coins" right now is a large one.

 Not sure yet where the GTX 1070ti is going to fall in the list - from the specs I expect it to be a better ETH performer than the 1070 and possibly the 1080ti but a hair worse on ZEC than the 1080, abet at enough lower of a price point to make it competative.

 I'm going to be putting one on preorder later today, as part of my "next card expansion" plans.

 Still debating if I want to get one Vega 56 (now that the pricing is finally dropping some) to play with - I think it might have a niche in my BOINC/Moo Wrapper/D.Net/GRC effort as it should have similar keyrate to a 1080ti at a LOT lower price point but I am worried a bit about the power consumption.

 I like the Zotac Mini 1070, but they're pushing the form factor quite a bit for cooling on the 1080 version and I don't even want to THINK about how hot the 1080ti version has to run.
 
1070 prices have been dropping for a while now - they're ALMOST back down to Febuary levels and availability has been good for a few weeks.

 The answer is "it depends on WHICH MODEL" - "AMD VGA" is a description that can be accurately applied to hundreds or possibly THOUSANDS of different GPU models, some of which can't mine at all a few recent of which would be fairly good BTG choices.

 Given that the algorithm is Equihash, the "which cards are best" discussion has long since been settled give or take pricing changes and an occasional mining software upgrade modifying the parameters - go look at the many ZCash (ZEC) mining threads.

 More accurately, thanks to the HUGE JUMP on almost all cryptocoin prices in the Feb-May timeframe that outpaced the rate of total network hashrate growth for months.

 What to mine only shows a very limited selection of cards - they have major space limits, it's not practical for them to show ALL currently profitable cards.

 The cards they do show are intended to be a "representative sample" of widely used cards more than anything else.

 Also, the figures they use for each card model are often OFF from actual production figures, depending on the specific card and the specific settings for the card - again, "representative sample" ballpark figures not YOUR actual numbers.
 They DO let you put in your REAL numbers though fairly easily.
