If you think that BitMain has too much control over the Bitcion ASICs out there being one of the main manufacturers on that particular market, then you might be happy to learn that there is a new alternative coming next year. There are of course the Canaan Avalon miners and the Ebit E9 miners already available, though they are also hard to get, just like the Antminers from Bitmain lately. The just announced DragonMint 16T Bitcoin ASIC miner from a new company called Halong Mining is looking very promising. What makes this announcement even more interesting is the fact that one of the Bitcoin Core developers – BtcDrak seems to be directly involved in the development of the miner and with Halong Mining who developed it. According to the initial information the project has been started quite a while ago with a lot of people contributing and with a serious investment in order to be able to bring the much needed competition and innovation to the Bitcoin mining arena. The only possible problem here is that it might still be hard to acquire for some small miners and users willing to get just a single ASIC miner to play around with once it becomes available, especially if demand from large scale mining operations is as high as it is with Bitmain’s products.

The DragonMint 16T is supposedly the world’s most efficient Bitcoin miner, running faster and cooler than any competing miners currently available. It is based on the DM8575 ASIC chips that run at 85 GHS per chip with power efficiency of around 0.075 J/GHS according to the developers. If you are wondering what is the catch here, well the new miner is not yet available for sale, it is expected to start shipping in March 2018 or in about 4 months from now. You can however already pre-order the device with a minimum order quantity and a regular price tag of $1595 USD (with first day promo at $1350 USD per device). That price does not include a power supply, just the miner, but you can also add a 1600W PSU for $125 USD ($115 USD on promo), though again this is a pre-order. As with all other pre-orders and promises for a new product that is to start shipping in the future it is advice to proceed with caution, especially in cases such as this one where it is from a newcomer in the crypto space (new company)!

DragonMint 16T Specifications:
– ASIC Type: SHA256
– Hash power: 16 THS
– Network: Ethernet port
– Miner power consumption: 1205 W ±6%
– Chip efficiency: 0.075 J/GHS ±6%
– Fans: dual fan variable 6000rpm (100W)
– Power Supply: Not included (1600W recommended)

antminer-r4-1

Bitmain is apparently setting a very ambitious goal of their new miner called AntMiner R4 and that goal is to bring back home mining of Bitcoin. What they are doing in order to get home miners’ attention is trying to make the miner more compact and less noisy while still managing to provide quite a serious hashrate rated at 8.6 THS with just about 845 W of power usage. What will make the most difference for home users however is the price of the new miner and if it is not right, then why would you bring one or even more of these home, guess we’ll know in a few days as sales start at 23:00 (GMT+8) on 29 August when we’ll probably also get an idea about the price of the device.


Bitmain AntMiner R4 Specifications:

– Miner Hash Rate: 8.6TH/s (Variation of ±5% is expected)
– Power Consumption: 845W +9% at the wall (with Bitmain APW5 PSU)
– Power Efficiency: 0.1 J/GH +9% at the wall (with Bitmain APW5 PSU)
– Noise level: 52dB (at an ambient temperature of 35°C)
– Chip quantity per unit: 126 x BM1387
– Default Frequency: 600MHz
– Rated Voltage: 11.60 ~13.00V
– Network Connection: Ethernet
– Operating Temperature: 0°C to 40°C
– Product size: 515mm (L) x 100mm (W) x 222mm (H)

antminer-r4-2

One of the most interesting things that you will notice with this miner is the cooling fan it uses, Bitmain calls is “a groundbreaking custom-design fan” that is intended to reduce the noise coming from the miner. Instead of using traditional computer fans (designed for servers) that are not intended to be silent, but instead to do their job providing good cooling they have opted out for a different design for the R4’s cooling. The fan that Bitmain uses in the AntMiner R4 is apparently inspired by the fan of a silent split air conditioner, so it was designed to make less than half the noise of the standard miner fan. Furthermore the rotational speed is being automatically controlled to ensure it never creates more noise than is absolutely necessary to keep the miner cool and running, so the noise will also depend on the ambient temperature.

bitmain-apw5

Bitmain will be also offering an optional custom-built PSU for further noise reduction to go along with the AntMiner R4 – the Bitmain APW5. The power supply works with both 220V and 110V (the standard in North America) input to deliver 2600W and 1300W, respectively. It has a dynamically controlled fan that runs at full speed only after heat sink temperature is 80°C. The Bitmain APW5 should start selling along with the Antmier R4 miner in a couple of days, do note that this is a 12V only power supply that is capable of delivering a very good efficiency of up to 93%. So it may be a great choice to go along with the R4, unless of course you already have some spare 1 KW or more computer power supplies sitting idle.

bitmain-antminer-s9-asic

One more announcement fro Bitmain, the AntMiner S9 ASIC Bitcoin miner is no official and will start shipping on June 12th for $2100 USD without the shipping cost (power supply is not included). The device uses the company’s new 16nm ASIC chips BM1387 and essentially triples the hashrate of the previous generation S7 miners while offering the same level of power usage. The Bitmain AntMiner S9 should be capable of 14 THS SHA-256 mining hashrate with a power usage of 1375 Watts at the wall, so definitely a good improvement over the S7.

Bitmain AntMiner S9 Specifications:
– Hash Rate: 14.0 THS ±5%
– Power Consumption: 1375W + 7% (at the wall, with APW3 ,93% efficiency, 25C ambient temp)
– Power Efficiency: 0.098 J/GH + 7% (at the wall, with APW3 93% efficiency, 25°C ambient temp)
– Rated Voltage: 11.60~13.00V
– Chip quantity per unit: 189x BM1387
– Dimensions: 350mm(L)*135mm(W)*158mm(H)
– Cooling: 2x 12038 fan
– Operating Temperature: 0 °C to 40 °C
– Network Connection: Ethernet
– Default Frequency: 650 MHz

The big question however is if now was the right time to announce the new mining hardware, as of you order now from the first batch you might be getting your units delivered right before the Bitcoin block reward halving. So it might be wise to wait for a later batch of S9 miners after the halving to see how the situation will change and if you might get a better deal in terms of price for the hardware. Then again if you are using S7 miners you might already get to the planning for switching to S9 now that the previous generation S5 is no longer profitable barely covering the electricity costs.
