Bitmain has just announced its next generation 7nm ASIC chip called BM1397 that is apparently capable of great performance and energy efficiency for mining cryptocurrencies such as Bitcoin (BTC) and Bitcoin Cash (BCH), that use the SHA256 algorithm for their Proof of Work (PoW). The new BM1397 ASIC chip requires lower power and can offer an energy consumption to computing ratio as low as 30J/TH or with other words almost 30 percent improvement in power efficiency compared to their previous 7nm chip BM1391 that is already found in the company’s latest SHA256 ASIC miners.

The new BM1397 ASIC chip is made using TSMC’s 7nm FinFET manufacturing process and it is expected to be featured in the upcoming Antminer models named the S17 and T17 that will be announced by Bitmain at a later date. There are no detailed specifications available for the moment, however ~30% better power efficiency could mean up to about 30% higher performance for the same power as the currently available AntMiner S15 and S17 ASICs that sue the first generation of 7nm chips form Bitmain. It is not all about performance however…

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.
