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

[mrb]

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

(1) Bitmain has already done similar things in the past. They released the S7 in Oct 2015, and barely 8 months later (Jun 2016) they released the S9 with next-gen chips & better efficiency.

(2) Bitmain's GPU rigs, even if obsoleted by an Ethereum ASIC, will still be viable for any of the numerous other GPU mineable coins.

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.  

Well, you've got the right idea but the wrong numbers.  Rx 580 @2Ghz has 256GB/s of bandwidth not 192 (R9 380 @1.5Ghz has 192).  ddr3 is available in x8 and x16, and since x16 has twice the bandwidth, that's likely what Bitmain will use.  Going with those numbers I come up with 250-300Mh/s.

Indeed, you are right with the bandwidth of RX 580, I found that 192gb/s from a shitty site, but your formula is wrong too. I made 2 mistakes, the first is the bad bandwidth, the second is that I used 64bit bitrate for 1 chip but 1 chip  has just maximum 16 bit/clock , this is refers to the x16 (or x8 or x4), 64bit is the bitrate of the full DDR3 stick with many memo chips. So we have 3x32 1Gbit chips. Let me recalculate this: 1.866*16*32*3/8/256*30=~39.3 Mh/s

Each core has 32x 1Gbit chips so you should multiply that number by 6 since there are six cores per board.

I predict it's going to be exactly 0 MH/s Vapourware.

Vaporware is often announced months or years before its purported release, with few details about its development being released.

How can any one of you even think it's not profitable for Bitmain to produce this mines, they will get instantly paid 20-30m $ .. and you are the one that might end up being f.... over if they move ethereum to POS ..

They don't care if this happens, they will bank on it instantly

[GrassBite]

Please STOP with the Ethereum POS crap.  It will be ONE PERCENT POS...if and when it finally starts...until they figure out if they want to go more.

That gives you forever and day.

Nail on the head with that.  Whether or not this thing is ever profitable for them to do is meaningless as they will sell out immediately when (if) they come out with them.  Insta profit, remember shovel salesman always win in the mining game

[timbereagle]

Mining profitability is constantly dropping. I had already sold all my rigs in December.

ETH asic would put nail on the coffin, I will not return anytime soon.

I really don't understand one thing.Everyone saying that If/when ASIC Miner F3 will be released, all gpu's miners will be useless and it will be END of gpu mining eth.

So you want to say that all people, all corporation who having hundreds and thousands of gpu rigs, who making hundreds of thousands $ mining eth, who have big farms of mining rig will be forced to stop and all gpus useless for mining eth? its really hard to believe...

[phuocduong]

need information about speed and power consum

They will not stop, just switch to different coins if difficulty will grow too much. Also even if Antminer F3 get's out and makes 200-300 Mh/s it won't stop people from mining with GPU, only new ones will switch to asic miner instead of buying GPU, because it will be cheaper. The miners who already mine will continue as their ROI was already achieved and those Antminers won't be a huge competition at first. Also if people will switch to antminers the GPU price will drop and building your rig will cost again around 2k, so it will help to lower the GPU prices.

Only if Antminer F3 will make 500+ Mh/s for the same price of 3k and only than GPU rigs will be useless...

Guys.. the first Eth ASIC miner is already here. ~200Mh/s, 700-750W, $2k

you can find it easily on google, but they are bought up instantly here in asia and the pre-orders are in the magnitude of hundreds (if not thousands).

so much for all the theories and math about eth asic being not feasible

That's not an ASIC, this is a MXM RX 470 GPU strapped on a custom PCB.

[Vann]

Guess this is what he's talking about. LOL

The Geass P1-200 Ethereum miner is the first Ether miner in the world. The hash speed (Ethash) is 198MH/s ± 5% with a power consumption about 730w. With this 198MH Ethereum miner, your Ether mining career will be speeded up.

^ yes that

I guess you could argue that's also a bunch of cheap AMD cards strapped together, but if the hashrate and power draw are true, then this beats any traditional eth mining rigs

7 heavily undervolted RX 570 consume about 750W from the wall while solo mining. There's nothing special in this.

hmm ok, carry on then. But still, those numbers beat what antmain is claiming about their asic, which is 200-220mhs @ $2500

when I inquire the company about availability, they said the demand is too big for them to handle atm and the wait will be "very long"
