Or the F3 isn't an ethash miner - perhaps it's for some other algorithm?

Equihash (zcash) has more room for optimization in an ASIC than ethash. The first round in equihash is dominated by blake hash speed, which is much faster in an ASIC than a GPU (and Bitmain already has blake miners). The subsequent rounds can be significantly faster with a modest-sized multi-banked SRAM. Something with 256 banks of 1KB should be at least 2x faster than a Rx 480, even if the ASIC is clocked below 1Ghz.

Turns out the Bitmain E3 (NOT the F3 as reported) is not exactly a big GPU mining killer.

180 Mhash
800 watts

Turns out bitmain is hiding the gpu killer --> F3.

Also this is interesting....

https://www.ccn.com/ethereum-developer-opens-eip-to-discuss-bricking-ethash-asic-miners/

An Ethereum developer has opened an Ethereum Improvement Proposal (EIP) to discuss whether the community should modify its Ethash mining algorithm to maintain ASIC resistance. The EIP is a direct response to reports that Bitmain — by far the largest manufacturer of mining rigs that use Application Specific Integrated Circuit (ASIC) chips — has developed an Ethash ASIC miner and will begin shipping them within the next several months.

- by the way the same proposal to change algorithm was for the SIA coin, after Bitmain launched it's miner. But finally SIA decided not to do so.

About the the SAME performance as a well-tuned 6 card RX 580/480 based rig, and slightly INFERIOR to a well-tuned 6-card GTX 1070 based rig.

On the other hand, at $800 they WILL sell these things probably as fast as they can make them, for a while.

First batch isn't shipping 'till mid-July though - achieving 100% ROI is going to be a bit iffy even if POS gets pushed back a couple more times.

http://shop.bitmain.com/product/detail?pid=00020180403174908564M8dMJKtz06B7

Note that Bitmain would have to sell well over ONE MILLION of these units to double the current ETH Network Hashrate (at current numbers right around 1.75 million, then add in a few hundred thousand more to cover ETC and the other forked ethash coins).
It took them almost 2 YEARS to achieve close to One Million sales on the S9, and the S9 is higher performance and efficiency than ANYTHING ELSE currently shipping.

Don't bother forking the algorithm on ETH for THESE miners, it's not worth the time and trouble.

If you read VB's twitter comments today about ASICs; he is open to them.
And is proposing a hard cap of 120 million ETH instead. While it will counter the evangelistic approach of ETH so far it will make it harder to mine eventually but the coin will retain its value somewhat i.e this is an anti deflationary measure. EIP 960.

-On the other hand we have EIP 958 open also. so please sign up/vote if you want to fork ETH. https://github.com/ethereum/EIPs/issues/958

I predicted this would happen, I told many times what would happen before it happened, sia devs got shot in the head. It served them well. Their greediness taught them a lesson.

Don't really understand why SIA community did not agree to change in algorithm? This might punish Bitmain at least.

Sia wanted ASICS for their network. Their machines the obelisks paid for. With btc already from last year.
If Bitmain rigs can replace. No loss for Sia Tech.

Wow how unfair to developers of Obelisc miners, and to those who has bought these miners , with delivery end of this summer...

I told the people buying the obelisks this would happen, they never listened, they never listen anyway. They got what they deserved as well.

The question is if eth devs will be bought up too by bitmain, 3 billion dollar company hehe, we will be back in this topic soon. I mean, Bitmain has been mining eth for 4 months and eth devs ignored that. I wonder why hehe

I know why and they will never officially tell anybody this, Bitmain bought them up, all of them to leave things as it is. Well in the end sia devs got their money and will earn a fraction of money as per asics sold by bitmain. It is all crooked business as usual.

From what I've heard the hashrate will be combined with the price, it barely competes with an optimized rig, I mean it's nothing like other ASICs, which I guess makes sense since Ethereum relies on memory speed, and using that massive amount of DDR3 doesn't seem very cost effective (I mean, why didn't they use DDR4)
Also the only confirmed Eth ASIC I've seen is really lackluster
https://www.eastshore.xyz/shop/ethereum-miner-geass-198mh-asic-miner-for-ether-mining/

That is NOT an ASIC rig, that is a GPU rig using "laptop" type GPUs.

They have had that GPU rig you talk about out on the Chinese site for more than 6 months, I think it was...this is really an ASIC from what I've heard....

I've also heard that the ram needed for this puppy to work, even as an ASIC is huge..thus around a 12k price tag..

with the price and possibility of a quick ETH fork looks beyond dangerous to dive in on

and if it is a GPU rig like the Chinese ones they have been pushing....it is cheaper now and better to make a NVIDIA rig..again from what I'm told

I don't GPU mine

anyway, my 2 bits worth

DDR3 is pretty slow for ETH mining, look at the GDDR5X it's slower than GDDR5 and DDR3 is way slower for mining, but it would be probably cost effective with those DDR3, seems like DDR4 are too expensive that's plus.

DDR3 has one advantage over newer memory architecture....it handles small chunks much better then DDR4/5

DDR3 memory is faster than GDDR5 memory when you only want to fetch a tiny chunk. GDDR is designed to access huge chunks with high throughput. DDR4 vs GDDR5 for a 128 bit fetch is no-contest DDR4 winner. In addition to that, FPGAs now support OpenCL, with a properly designed FPGA setup, a miner with an OpenCL shouldnt even notice its running on a FPGA

This will be interesting to see it finally make it. One thing is for sure, it's going to kill GPU mining when all those rigs start switching to other coins

it already has killed gpu mining...
its been out since last year. bitmain did this exact strategy with monero asic... how do you not see it ?

Antminer F3 is already there in the wild?

That's a first april prank! The real time hash rate doesn't match Cheesy

I've looked at every antminer version that I own and they all match in real time

hahahahhahahaha look how fast it is now.

all of you now you see.
