Title: Dragonfly miner (256 mh eth)
Post by: Tmdz on September 26, 2016, 06:08:18 AM
I came across this miner tonight in a slack channel.

https://translate.google.com/translate?hl=en&sl=ru&u=http://www.cryptonyka.com/tech/8-dragonfly-ethereum-miner-d1-256mh.html&prev=search

It's called the dragonfly miner and it basically looks like they pulled 8 rx 480 chip and plugged it into a board then did some optimization.  So it seems it is not an asic but just a really huge gpu that can mine most altcoins.

Price looks to be in the range of ~$3300

They're saying 8 AMD 480s to get to 256 MH/s - which isn't unreasonable if you can push them hard enough.

 The hashrate they're quoting is not $800/month though - that's VERY close to what I get out of my farm, and I only see about $520 right now NOT counting electric use mining ETH (they might get a bit more on XMR but that's gonna vary and XMR isn't a LOT more profitable than ETH if at all).

 127 day ROI is NOT realistic unless the price is pretty low - where IS the price, I don't see it quoted anywhere on the page you linked?

They won't say the price since they sell in bulk.

But you can speculate the price is the roi they claim 127 days times the best profit they claim 800 month.  So that gets you in the ballpark of 3300 take or give.

man you can do 200mh for 600w with 6x1070, that thing is trash

Interesting, but something about this doesn't add up. I don't think it's a simple as 'lifting' the GPU cores from the 480 and putting them on a different logic board to make something like this functional.

One of the pics looked like they take a standard card, mount it on a custom multi-riser setup, then put a custom passive HS on each card.

 If they ARE charging $3000+ for the things, it's just a straight "gouge you because it's pre-built and pre-configured" situation and fairly likely to be legit.

Ha. Haha.

You deserve you lose your money if you send them anything.

@Prelude  no one here will send them anything, especially considering they take bulk orders only.

@QuintLeo Yeah I thought about it later and that seems most likely, in the etc slack the guy says each gpu can achieve 38mh so that is pretty good.  But it's all slapped onto this thing so if a card goes bad then you're out of luck, where if you buy the gpu standalone you have 2 years of warranty and easy resale.

I thought it was interesting to post about.

hmm its strange, because if you say price looks to be in the range of ~$3300, its over budget if we buy antminer s9 because s9 its about $2300 if i am not wrong. so better you buy s9, or with that $3300, you can build new computer with 4-6 vga inside by your ownself rather than you buy that.

you can take a look on amazon, ebay, aliexpress, there are many hardware mining and there are more lower than that price. i hope you can find another info if finally you decide to mining at your home.

You can build a pair of 4GPU RX480 based rigs for less than this thing appears to cost, and have a high probability of better reliablility and MUCH easier resale ability.

Without the actual price, though, I can't say for sure that you could build *3* 4 GPU rigs for the same price.
