Topic: Bitmain has released two GPU miner models: G1 and G2 - page 3. (Read 12812 times)

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

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.

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.

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.

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.

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

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.

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

Strange that the design of the 2 is so different.

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

holy crap

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

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

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

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?

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.

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.

seems so,
very interesting and the prices are attractive too

Gpu is also in?

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