It Is All About BTC, LTC, ETH, DOGE, KAS mining as well as other alternative crypto currencies
Canaan Creative has announced heir second generation 7nm AvalonMiner ASIC – the A10 that should be capable of delivering 31 THS SHA256 hashrate with 1736W of power usage (56 W/THS energy efficiency). The 30 THS efficiency with 1700 Watts of power usage was supposed to be delivered last year with the announcement of the first 7nm ASIC miner – the Canaan Avalon A9, however the first generation 7nm hardware was not able to deliver what was promised. Not to mention it came at a bad time for the mining and crypto in general – a declining profit and the whole crypto market going down, so the demand for the new devices was really low. Instead of 30 THS, the AvalonMiner A921 was only capable of delivering 20 THS at 1700W of power usage, so the new 2nd gen A10 devices should finally be able to deliver that level of power efficiency. No word yet on pricing and exact availability dates, the official website still does not list the new devices and Canaan is talking about March availability and they just made the announcement at the end of the month, so we should wait a bit more for additional details…
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.
While we are still waiting for the upcoming Avalon A9 Bitcoin ASIC miners that will be based on 7nm technology, Canaan Creative has apparently started selling AvalonMiner 851… the successor of 841. The new AvalonMiner 851 is based on the same 16 nm A3210HP ASIC chips that the 841 uses, though apparently there have been some optimizations in order for the new model to reach 15 THS up from 13.6 THS for the 841 version. So with Canaan AvalonMiner 851 you get 15 THS hashrate for Bitcoin mining with 1450W of power usage, allowing for a slightly better hashrate density, but not much of an efficiency improvement in terms of power usage. It is interesting to note that at the official Canaan website the AvalonMiner 841 is listed at $425 USD while the 851 is at $450 USD or just 25 dollars more, though wit distributors the price difference would be higher.
