I just noticed that Bitmain has released two GPU miner models at their Chinese section of the web page.

Any thoughts about these GPU card miners?

I was pretty surprised to suddenly find these.

The link seems to be invalid, do you know the prices?
I would not buy those, I prefer to build my rig myself, I am just curious

Prices are 18700 CNY and 19700 CNY for the G1 and G2, respectively.   That translates to $2862.43 and $3015.51.

Gpu is also in?

seems so,
very interesting and the prices are attractive too

You need first to click yourself to the Chinese part of the www.bitmain.com, then those links should work.

Yeah, it is about in the same price category with the Pandaminer.

I think it is a bit better to build your own, more fun to.

But this confirms that asic is impossible for modern memory hard algos, as bitmain would have made an asic instead of going this route if they could.

The main question I always get also with Pandaminers, why would you spend that much for so little payout.


It takes ages to recoup the investment. How reliable to you think are those? I got little knowledge of GPU miners to be fair. Just the numbers are not attractive lol.


I spoke to someone who said he would build the rig for around 2500. Don't know the output of hash,  but if I don't need to worry about building the rig myself i would gladly pay 300 bucks more.

Any input on this?

So now... we have to compete with Bitmain grabbing all those GPUs - well played NVIDIA & AMD

I thought exactly the same, I was asking myself why with this low profitability there are no GPUs in stocks.
I think I found the answer I was looking for

Maybe Bitmain is getting ready for Bitcoin Gold GPU mining ... ?

holy crap

Strange that the design of the 2 is so different.

 Pricing, like the Pandaminer, isn't all that impressive.

GPU mining for the non home miners, these guys are just killing decentralization aren't they?

I don't really see any reason why a home miner should buy this, its probably noisy as shit and is a little more expensive than you can buy

I agree with you. I also build rigs for people and lately I'm getting a lot of customers who used to "build computers themselves" when they were younger and try their hand at mining rigs. They don't know all the pitfalls they will face and eventually call someone for help. This is an attractive solution for someone who just wants to pay for a miner. For those of us who build ourselves, we would never buy this so I don't think we are the target. For someone like bitmain who would clearly get products at a discount, it's a no brainer to offer it to customers.

Actually those prices are quite good for people who live in Central Europe and do pay taxes. I agree that build a rig is interesting, but if you wanna scale a little bit (e.g. 10 rigs) those are a good options

They are meant to be in industrial farms and are designed to be noisy and compact.

Pandaminer wasn't really a threat because that company had no money.

Bitmain on the other hand, probably bought out millions of these 570 GPU chips and will be building these like crazy.

Keep in mind that most industrial/commercial farms that buy these usually don't buy 1 or 2. They usually buy them in quantities of 100/1000 units.

So probably not a good idea anymore to be buying any RX 570 from Newegg.

These products are for factory mining.

I don't really see any advantage to the home miner.

Comments

1) Maintenance

a) BM hardware maintenance/repair is not good. I can't image waiting weeks to get a GPU miner back up. This is an area where the home miner will excel. At the most primitive user level, all you would have to do is component level swap/replacement on a homebuilt setup.

b) If BM has their own special S/W it's a TI and DEC PC's vs  IBM/windows repeat.

2) Ultimate cost of ownership.

a) The value of the GPU's (1060, 570) in these systems will lose value faster in terms of cost of ownership and revenue generation. At this time, I believe the flagship 1080ti is a better value in terms of ultimate cash flow.

b) Home builders should be purchasing the high quality sub components and just swapping out GPU's.

c) I believe that this hardware will not in general be as adaptable  as a home rig.

 Just to hot dog a little bit, I have been deploying on and off since the end of the BTC GPU (2014) era, ASUS Z87-PLUS motherboards. With Win 10 pro and some 1080ti's, in their latest deployment, these motherboards currently make up a  4 GPU system miner.

If you have been attending the Phil Ma school of GPU mining, his way has to be cheaper than the BM behemoth. I still believe the edge is to the home miner.

Furthermore the good news is that this indicates a good outlook for GPU mining.



A potential ethical problem for this MB will be helping the owners of these systems, a system which is geared towards marginalizing their GPU mining efforts.

Tl;dr Bitmain made a miner similar to the Pandaminer to compete with GPU rig sellers. Considering how many fools buy prebuilts this could be quite lucrative for them. Resale is definitely an issue, but I guess that's a risk buyers will take. Many parts seem proprietary in some way or difficult to replace, which is my main worry.

No way. We're back to earning $1/card/day and your talking about over 1 year ROI on this ASSUMING mining doesn't get any less profitable but looking at network growth over the last 2 months you'll never get your ROI on these.

I would also say do not buy these. Better to spend money on their ASIC equipment or build your own gpu rig.

let see the review from someone who use this thing.. :)

Yeah it's safe to say you can forget about these. Its much cheaper and way more profitable to build your own rig in the long run. A big plus to building your own rig is the resale value of the GPUs. If and when mining eventually becomes unprofitable you would be stuck with this big behemoth of a machine that can't do anything.

but these will sell

8 gpus   any 1151 cpu   1 sodimm stick of ram

a riser free build

Agree. I can build those same rigs for $1K less than what they are selling. Plus all mine have value throughout their life cycle.

I think I would upgrade to these tho. so much easier.

But way less fun!

Since buying BTC with CNY is illegal in China now, most likely people will be buying these and even mine at a loss just to earn BTC.

yeah all my miners are solid working psu's   I go riser free.

with better cpus .

the mobos I linked would be nice to have.

Agree for that. We all know how long the warranty process, its better to buy part from local shop and build it yourself, and its fun too.

Agreed with most of the opinions that building GPU rigs is way more fan,rewarding and economical, with the help and participating in philipma's Thread i will built both Onda motherboard based 6 GPU rigs and Colorful motherboard based 8 GPU rigs.

Meh - just too much hassle and risk to order these from China. So much more fun building your own - and cheaper in any case. Nice try Bitmain, but NO thanks.

I run several different models of Pandaminer and personally love them. I get that one-off home miners want to build theirs to save money but if you run volume the simplicity of pre-built custom systems is a blessing.

50 in a good room with venting and good psu's  can be setup in a day.  So for a larger farm you are correct.

I wonder what all those PCIE power connectors are for? I get one to power each slot but the second set?

Yah - I saw that as well.  16 PCIE on the motherboard and then add another 16 for 8x GPU cards (at least for the 1080ti cards) for a total of 32 PCIE.  That's quite a lot.

99 percent sure


the 16 on board are 8 input  on the end.

the other eight go into your gpu

they may want you to use  1060's in the board.

if that is the case  it would be a nice  board not a great one.

eight of these

may be what the board is designed for.

What's to stop you from tearing the unit down and parting it out, same as a home built rig?

These are worth the extra $ compared to buying a pandaminer, especially if your dual mining.

a nice addition to eth network i guess , and may bitmain also add multi algo mining to that gpu miner

imho , i will still build usual mining rig with used part , and brand new gpu with 1-2 year warranty

I still could not figure out why Bitmain G2 uses more expensive CPU, RAM and SSD than G1's.

Even though I have no clue about GPU rigs, I would say they go with the normal principle of "Someone always wants to pay premium and buy the most expensive" 

Looks like now the both GPU miner models are available via Eastshore for international sales also.

Hello

can anyone help me with the setup of this G2 miner, got in few days ago spent day and night and its not working, no support from bitmain as usual, seem like one of the crap miner they made.

ok here is the story

its came with centos 7 which never used it anyway they also put folder of claymore 9.7 which i tried and give error message of OpenCL error - 4 - cannot create DAG on GPU
in the read me file says something to do with virtual memory but how to increase this

on 2nd machine g2 i put windows 10 after too much struggle finally fiudn the drivers but only 8 cards supporting when i put 8th card this crash the system

my advice not to buy these g1 nor g2 waste of money and time

any advice plz

No idea if it’ll support your G2 or not but you could try nvOC https://bitcointalk.org/index.php?topic=1854250.4100 (https://bitcointalk.org/index.php?topic=1854250.4100)

I agree. I'm making my own now. Not only it's more fun but if you take some time finding some good deals locally, you can build a 220MH/s it at less than half Bitmain's price. Especially in Europe that that 3k usd translates to 4k euro after import.

And there is the resale value people have mentioned. A custom made rig can break and sell the part individually at some times above cost. Who is gonna buy Bitmain's custon 570s?

Well....what a surprise.....another large corporation that is trying to crush any opportunity for regular civilians to make a business or money on their own. A large corporation that has more money than they could ever spend. This time hopefully they stepped in it. The Bitmain ASIC's business model, does not appear to carry over well to the GPU market. It is inherently grass roots and homegrown. I hope like Hell it can stay that way.

They are nVidia 1060 and AMD 570.

Basically this Bitmain GPU Miner is for the lazy.

Next they'll be bringing out their own Bitmain Blockchain and Exchange.

hm 3k for a 200 MH GPU miner you can build your self for less.... they pay it .. sadly ..... or a fool and his money .....

I agree that's what it is and i do hope this time bit main has there ass handed to them for being greedy ...

I hope it stays that way  to:  the GPU market. is inherently grass roots and homegrown. I hope like Hell it can stay that way.

speaking of grass root nm i won't go there .....

LOL. I get it.  ;D GPU mining seems like the only thing left in Crypto that adheres to the original ethos of how this was intended. Hell with all this corporate rape.

I prefer to build my own and these depend on price if thye are cheap from China they will sell
and they only seem available for the Chinise so I dont no why they are debatable

Wonder if anyone has actually bought any of these. Considering the entire miner is pretty much fully custom it'd be hard to resell its parts and it's cheaper to just build it yourself. Besides that you will also need to pay for shipping from China and customs, and Bitmain also has a horrible record as of now.

I noticed this review few days ago.

Antminer G2 GPU Mining Rig Review: Let’s Mine Some Altcoins
https://www.bitsonline.com/antminer-g2-gpu-mining-rig-review/

Looks pretty nicely built to me.

So you dont know what you are doing and that is bitmains fault? God its disgusting how everyone uses bitmain as the scapegoat for everything. How dare they become a successful company when others have failed? I mean they should just close up shop right?

Interesting products, but I was hoping for new asic miners with some exotic algos :) Maybe soon....

Price is too hugh

Does anyone know the hashrate for these G2?

Bitmain is going to release them soon again (to buy), wondering if its worth.

G2 is 220

It is listed on their Chinese site but not available, conversion is about $4300 USD.

is this website legit and trusted ?
anyone has experience with them ?

The items are sold out
