[2018-02-12]Bitmain To Release Ethereum ASIC Miner F3 With 72Gb DDR3 Dram In Q2

[helovescrypto]

Thank you for sharing this important message. I hope the influential folks can talk more. Tell us the plan and reaction.

650mh/s with 72 DDR3 memory? Its Simply Nonsense, and I tell u why:
So what we know is the RX 580 has 192Gb/s bandwidth and able to perform ~30mh/s
Well if we choose the best DDR3 memory with 1866Mhz (1866000000 Hz) then we can calculate 1 ddr3 memo chips's bandwidth. It's has a 64bit lane so 1866000000*64*8/1024/1024/1024=14.9 GB/s this is 1 DDr3 memo chip's bandwidth.
14.9*72=1074 Gb/s this is the total memory bandwidth with 72 ddr3 chip. So 1074/192*30=~168 Mh/s this could be the maximum eth mining performance with 72 ddr3 chips. Everything else is bullshit. 

These numbers are correct.

The only interesting factor remaining is power consumption. If it's around 500w AND priced well it could be worth buying but nothing to get overly excited about

168Mh/s @ 500W? There is no point in buying that asic, every 6x 1060 3gb with samsung will give you 140Mh/s @ 460W. Better resale value, not mentioning the warranty...

You are talking about GPU for gaming and not full system design to mine ETH. Think about optimisation in code and so one...

[dagarair]

It's not going to be an asic per say.  It will more than likely be a chip or 8 with a shitton of ram.  It will be about 200 has like the 8 card rigs out there already.  Of course no one really knows anything about anything as its all hearsay.  If they could keep such a tight lip on A3 I find it hard to believe they would leak this...

[Jantapw]

why would anyone buy Ethereum miner when eth plan to shift POS?

[ggbtctalk000]

Wonder what Ethereum developers will do if it turns out to be true? If you develop something specifically to be ASIC resistant, obviously IMHO you don’t want ASICS mining your coin. If someone makes an ASIC anyways, knowing you don’t want them mining your creation, then fork your coin and make their ASICs bricks. They will think twice about doing it again.

You must be a troll correct? Their asics can act like a video card concerning algorithms, even if eth devs change the algorithm, their asics can still mine the algorithm. I advise you trolls get to reality and stop paying $1000 for a rx 580, What got you trolls on this situation are yourselves.

I doubt they would have created an asic for ethash if rx 580 was selling for $180, like it used to be before the bullshit.

LOL... Troll... No.... Opinionated... Yes.... I've worked in I.T. for quite a while, so please elaborate when you say the ASIC can act like a video card??? Never heard of an ASIC capable of doing ANY algorithm because they don't exist. A true ASIC is purpose built to do one specific thing in a very fast and efficient manner... If it can adapt to multiple algos it sounds more like an FPGA to me.

dont listen to this metroid trolls all he does is scream around the forum to make baseless, ignorant trolls to confuse newcomers.

[badger88]

this will correct the GPU demand by eth miners hoarding and retailers hoarding old GPU and selling at a huge markup..

everyone needs to completely flood the networkhash rate mining with 2-3 of these asics...


then GPUs can finally be at their real price point for gamers

sounds good ... how long until release..-like 3 weeks ?

It will take many steps/years for ETH to be fully POS.

Yes, this is what I was thinking as well.  A few people in this thread have said it would be impossible for memory at that speed to hash at a rate higher than what the video cards can currently do, but my thought was that if you had a dedicated ASIC chip designed to do nothing but that math well, connected directly to memory, all highly optimized for nothing but that math, then it just might be possible.   But, this is all speculation so far.  It would not surprise me if Bitmain does release this.   I remember seeing that Samsung was getting into supplying chips, could they be supplying the memory chips for this new Bitmain asic perhaps?  It's all very interesting :-)

[Reigningchamp4eva]

Also remember they are using leftover DDR3. Overall price may be cheaper than you anticipate. If they hit 5x 580 performance at 1000 dollars and 1/2 power they'll sell out like hotcakes.

[toptek]

why do they call it a ASIC miner when it's using DDR3 memory .... the way it reads after i looked at the press release .....when it is clearly not a ASIC miner unless I'm missing something .


"I think ASICs are inevitable when the coin is valuable. But that’s not a bad thing."

why are ASIC miners not a bad thing when we saw how bitmain destroyed mining any thing with GPU aka ltc and btc ......an sia .... which you can't mine with gpu's any more ...because of there greed . an it is greed ...

On the other hand if they would keep there prices down and make ASIC miners for homes like they used to, i would agree but they don't any more .....

Looking at the specs it seems each core has a total of 4 GB of memory. That's going to be an issue in the long run since once Ethereum reaches Epoch 384 the DAG file size will be too large to fit in 4 GB. At the current rate that's going to happen in the beginning of 2021. However, should Ethereum devs decice to speed up Epoch switches then that deadline could be hit much sooner. It seems like an easy way to render the ASIC out of date without resorting to hard forking the algorithm or switching to PoS.

They would NEVER do that because at the same time youd screw over everyone with a 3 or 4 GB GPU.... That means all 1060 3GB's, all 1050ti 4GB's and any RX 470/480/570/580 with 4GB (which is the major one here).

Epochs will never be "sped up".

Good joke. You guys realize that Bitmain sells GPU rigs? They wouldn't have started selling GPU rigs if they had an ETH asic in the pipeline and release it 6 months later, not to speak of the numbers not adding up.

By the way there was a rumor last autumn :    Bitmain Debuts High-Speed Ethereum GPU Miners After Dash Rollout

"Currently visible only on the Chinese version of its site, the G1 and G2 provide Ethereum GPU mining at up to 220Mh/s."

Article of 5 months old :

168Mh/s @ 500W? There is no point in buying that asic...

"hash will be 200-220 MH / s.   Price -    $ 2500- $ 3000."
-------------------

16 February 2018
The world’s largest producer of mining equipment Bitmain is working on the creation of Antminer F3 - ASIC-miner for the second largest capitalization of crypto currency Ethereum. This is reported by IBTimes referring to local technology publications. This is reported by Ib Times.

As the source notes, Antminer F3 will be equipped with three motherboards in each of which will be installed on six devices for the Ethereum mining. Each board will have 32 DDR3 RAM modules with a capacity of 1 GB. According to a number of sources, the hash of the device will be 200-220 MH / s, but with the specified specifications, this figure can be expected to be higher

It is assumed that the production of new equipment for the production of ETH will begin at the end of this month. In the world market the novelty will appear approximately in II-III quarter of this year. The price of Antminer F3 will be set at $ 2500- $ 3000.

Not saying they would or should do it but why would Eth devs care about 3/4GB GPU miners? There's still plenty of 6/8GB GPU miners to keep the network safe and decentralized.

I suggest mods close this thread right away and label as "B.S. from china topic doesn't belong here".

Lets get over this already, seriously... Anyone who knows anything about ETHASH knows this F3 is B.S.
