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.

Innosilicon has just launched another BTC ASIC miner called T2Turbo+32T, a 32 THS miner that can run up to 36 THS according to the company with a power usage of 2200 Watts. What the company did with the new miner is to use the same 10nm ASIC chips like their previous 24 THS T2T-24T Bitcoin ASIC, but adding more chips running at lower operating frequency and delivering better efficiency per Watt. The efficiency in normal mode is 68 W/TH and the miner can apparently run in high-performance mode delivering up to 36 THS. Innosilicon currently has a special promotional price for the Innosiicon T2Turbo+32T of $1568 USD for online order with limited quantities available.

It seems that Innosilicon might be taking the lead in ASIC chip development for mining crypto currencies lately in terms of performance and efficiency even though it is not the largest company in this sector. Probably the fact that matters here is that the company has been designing and manufacturing chips even before venturing in the crypto mining market unlike most of the dedicated crypto ASIC manufacturers. What they still do seem to need to address however is their customer communications and service as this is what most customers that have some issues with their products issues are complaining from with Innosilicon

We can’t confirm for sure yet, but we are seeing a lot of reports coming from Asia about what seems to be the first Lyra2REv2 ASIC miner called DAYUN Zig Z1 getting released. A 28nm-based ASIC miner that is capable of producing 6.8 GHS Lyra2REv2 hashrate with about 1200 Watts of power usage (176.5 W/GH efficiency) is apparently already available for sale with a price range of about $8000-9000 USD. This would mean that profitability for GPU mining coins like Monacoin (MONA), Vertcoin (VTC), Verge (XVG) and others using the Lyra2REv2 algorithm will start dropping further making them unprofitable to be mined with GPUs really soon. It is interesting to note that none of these popular Lyra2REv2 coins is showing significant change up in their network hashrate lately, meaning that either these devices are just getting out of production now and on sale, or they are being produced just now…
