Bitmain AntMiner K5 ASIC Miner for Eaglesong used by Nervos (CKB)

6, Mar 2020

It seems that the Todek TODDMINER C1 is not going to be the only Eaglesong ASIC miner out there, Bitmain is also joining the fun with their Bitmain AntMiner K5 ASIC miner. The TODDMINER C1 promises to deliver 1.6 TH/s hashrate with 1100 Watts of power usage with $4100 USD price and supposedly already shipping, while the Bitmain AntMiner K5 is rated at 1130 GH/s hashrate with 1580 Watts of power usage and a price of about $1400 USD or significantly cheaper. Bitmain plans to start shipping the K5 Eaglesong ASIC miners in the first half of April and they are only available on their Chinese website for the moment. Eaglesong mining has started with GPUs and has relatively quickly moved onto FPGA mining and now it seems the transition to ASIC mining is starting to take place. Hashaltcoins BlackMiner F1+ does 22 GH/s and F1-Ultra does manage t get you 26 GH/s hashrate at the moment, so ASIC miners will really offer much faster performance when they become available and will significantly increase the total network hashrate.

Bitmain Has Announced Their New Antminer S19 Series ASIC Miners

27, Feb 2020

Bitmain has announced their new Antminer S19 series of SHA256 Bitcoin ASIC miners, though only specifications for now, no price and availability info. The Antminer S19 has 2 variants, a 95 TH/s and 90 TH/s model, with a power efficiency of 34.5 J/TH and the Antminer S19 Pro has a 110 TH/s and 105 TH/s model, both with a power efficiency of 29.5 J/TH. Both series come with a built-in power supply and are rated at 3250 Watts of power usage at the wall utilizing the new APW12 high-conversion efficiency power supply.

Bitmain is trying to up their game with the Bitcoin halving nearing, though the new ASIC miners will most likely be available for delivery soon before or right after the halving, especially with the current situation in China regarding the coronavirus (covid-19). There are already some numbers regarding the price around $5000 USD per unit for the Pro coming from Hashnest (owned by Bitmain), who already list the 110TH/s Antminer S19 Pro as available for rent, though nothing is yet confirmed as final price for the units that will go for sale and when hey will be available for delivery. Anyway, still good to see that BTC ASIC miners’ efficiency can be further improved with optimizations and new technology…

Are Bitmain’s Antminer E3 Ethash ASIC Miners Becoming Obsolete

24, Feb 2020

It seems that the life of the Antminer E3 ASIC miners from Bitmain is nearing its end with the Ethash miner apparently becoming useless for Ethereum Classic (ETC) mining and soon for Ethereum (ETH) as well, or at least we are getting such reports form users being unable to mine properly ETC these devices anymore. The reason for that is the fact that they do work like video cards with 4GB video memory and as these become obsolete due to large DAG size (even though not yet 4GB in size), so will do the E3 ASIC miners. ETC is the first to drop from the E3 coins to mine as it is ahead with about 10 epochs from ETH (328 for ETC, 318 for ETH), so Ethereum has less than two months left before reaching the same place as ETC did. Of course there are a number of other smaller Ethash-based projects that are far behind with their DAG epochs, so the E3 miners will still be able to be mined with the ASIC miners. The problem is what will happen with profitability with a big influx of hashrate coming from large E3 mining operations, so most likely very soon it will be time to retire the miners.

It is interesting to note that Ethereum (ETH) does have a plan to do another fork and switch to the ProgPow proof of work mining algorithm (GPU-only mining) at some point this year, and the time could coincide with the “E3 miner death” for ETH mining or not. Nevertheless now is definitely not the best time to be buying Antminer E3 even if somebody is offering the hardware at a really low prices as in less than two months it might become pretty useless. If you do have E3 ASIC miners make sure you maximize their use for the remaining time that you should be able to mine ETH with them and start planning what to do with them afterwards.
