Bitmain with Two New 7nm ASic Miners – Antminer S15 and T15

9, Nov 2018

Bitmain has announced its next-generation 7nm miners – Antminer S15 and Antminer T15 and is already taking orders for the new devices with estimated shipping time for the second half of December. Both new Bitcoin ASIC miners have two different operating modes – a high-performance one for maximum hashrate and an energy saving mode that offers better energy efficiency with lower power usage and reduced hashrate. Antminer S15 is available for $1475 USD with a limit of 2 miner per user and Antminer T15 for $913 USD with a limit of 50 miners per user. The new miners do come with a built-in power supply included in the price, but be aware that apparently this PSU is only for 220V input power and also the output voltage is not the standard 12 used previously, so finding an alternative power supply may turn out to be a bit of a challenge.

The Antminer S15 high-performance mode can achieve a hash rate of 28 TH/s with a power efficiency as low as 57 J/TH (1596W); its energy-saving mode can improve power efficiency to 50 J/TH while maintaining a hash rate of 17 TH/s (850W). The Antminer T15 high-performance mode sees a hash rate of 23 TH/s and a power efficiency as low as 67 J/TH (1541W). Its energy-saving mode can improve power efficiency to 60 J/TH while maintaining a hash rate of 20 TH/s (1200W). The new Anminer ASIC miners come with a new high conversion power supply APW8 that has a non-standard 16-18V high-voltage output, so they can effectively reduce the power loss during the power conversion process, helping mining farms save on electricity costs, or so Bitmain claims as a reason to include the new power supply module as a part of the miner. The only problem is that the new power supplies are not designed to operate on 110V power grids and that can present a challenge for some regions that do operate on these.

MicroBT WhatsMiner M10 Bitcoin ASIC Offering 33 THS at 2145 Watts

20, Sep 2018

WhatsMiner M10 is a Chinese Bitcoin ASIC miner that is apparently starting to ship just now that promises performance comparable to other top SHA256 ASICs available on the market at the moment. At 33 THS with 2145 Watts of power usage it is surprisingly efficient for 16nm chips available at a price of $2000-1800 USD including a power supply. What is more interesting though is that MicroBT, the manufacturer of the WhatsMiner, has just announced their next product called WhatsMiner M10S that will supposedly be able to deliver up to 55 THS with about 3500W of power usage at 65W/THASH or 44 THS with about 2600W at 60W/THASH power usage.

Whatsminer M10 Specifications:
– Chips: 315 * 16nm ASIC
– Hashrate: 33TH/s (+/- 5%) (depends on cooling)
– Power Consumption: 65 W/THS, 2145 W per miner (+/- 10% )
– Power Supply Unit: WhatsPower P5, 2500w, 93% efficiency 220V
– Operating Temperature: -5C ~ 40C
– Dimension: 34cm x 20cm x 17cm
– Weight: 8.55 kg

The only problem with ASIC miners going forward with higher performance is the increased power usage and that is causing trouble for people that are running smaller mining farms, let alone small home miners that do not have the infrastructure available that is capable of handling this high power usage per device. Anyway, with the current market situation it is arguable what is wiser to do – invest in Bitcoin mining equipment or buy directly BTC and hold, that is if you are investing fiat, not crypto.

Canaan AvalonMiner A921 Bitcoin ASIC Miner Specifications

19, Sep 2018

The Canaan Creative has posted official specifications of their new AvalonMiner A921 Bitcoin ASIC miner and the device should apparently soon be available for order, though no prices have been announced for the moment. We were kind of expecting the new 7nn-based Avalon A9 ASICs to be able to deliver 30 THS with about 1700W of power usage as per earlier information available, but apparently this will not be true for the first model A921, though it can happen in a later revision of the A9 series. Instead the AvalonMiner A921 will be a 20 THS SHA256 ASIC miner with 1700 Watts of power usage apparently…

Canaan AvalonMiner A921 Specifications:
– Hash Rate: 20 TH/s, -5% ~ +10%
– Power Consumption: 1700 W, +0% ~ +20%
– Power Efficiency: 0.085 J/GigaHash Wall-Plug
– ASIC Chips: 104x A3206 7nm
– Operating Temperature: -5 ~ 30 degrees Celsius
– Dimensions: 378 x 170 x 155 mm
– Net Weight: 5.5 KG

The A921 specifications might come as a bit of a disappointment for a new 7nm chips, but we are more than likely going to be seeing an improvement in next models from the A9 series and hopefully they will soon be able to soon reach 30 THS at the same power usage that the A921 has. Of course pricing of the devices is also a very important factor, especially in the current market conditions you really need to offer not only good specs, but also an attractive price. Compared to these specs, the just announced 14nm BitFury Clarke ASIC chips do look more interesting, though these are not very likely to be soon available in consumer level Bitcoin miners.
