The newly announced Innosilicon Terminator3 ASIC miner capable of delivering up to 43 THS SHA256 mining hashrate with just 2100 Watts of power usage (48.83 W/TH) is definitely interesting technologically wise, though in the current market situation pre-ordering mining hardware for next year delivery is significantly more riskier. The Innosilicon Terminator3-43T is up for pre-orders at a price of $2279 USD or about half of Bitcoin at the current low prices, so buying with BTC may not be a wise idea at the moment. Delivery the 1st batch is expected to start between January 25th and February 25th, 2nd batch is for March 5th to March 15th, 2019. One thing is for sure however, the competition for more powerful and more efficient ASIC miners is heating up even though the market is declining at the moment, apparently everyone is already gearing up for when things pick back up.

Innosilicon Terminator3-43T Specifications:
– Hashrate: 43 TH/s (+/-5%)
– Power Consumption: 2100 W (+/- 10%, normal mode, at the wall, with 93% efficiency PSU, 25°C temperature)
– Dimensions: Single Tube, 430mm(L)*141mm(W)*220mm(H)
– Net Weight: 10.02 kg
– Ambient Temperature: 0-40° C
– Network Connection: Ethernet
– Note: ASIC Boost Enabled with a proper license

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-s3-asic-miner

BitMain has listed the upcoming ~500 GHS AntMiner S3 Bitcoin ASIC miner on their website based on the new 28nm BM1382 chips that were recently announced. The AntMiner S3 should start shipping from July 10th with a price set at 0.75 BTC, so you can already pre-order your unit if you are interested. The initial effective hash rate for the S2 was announced to be 504 GHS plus/minus 5% and now it seem that Bitmain has lowered it a bit to 478 GHS, though the unit should be overclockable to 500 GHS or more. The power consumption for the 500 GHS hashrate that was previously announced was 390W on wall and now with the official hashrate lowered a bit the power usage is also a bit lower at 366 Watt.

AntMner S3 Final Specifications:
– Hash Rate: 478 GH/s±5%
– Power Consumption: 366 Watt at the wall
– Power Efficiency: 0.77 J/GH on wall
– Power Supply: 12V DC
– Size: 331 mm x 137 mm x 160 mm
– Fans: Two 14038 fans mounted on both front and back ends.
– Operating Temperature: 0 °C to 35 °C
– Complied with: FCC / CE
– Network Connection: Ethernet

Do note that the BitMain AntMiner S3 ships without a PSU. There are 4 PCI-e connectors for +12V DC input, but it apparently needs only two of them to be connected if you are not going to be overclocking the device, so the other two are required only if you do plan to overclock the device.
