Canaan AvalonMiner A921 Bitcoin ASIC Miner Specifications

19 Sep

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.

IF you have FREE energy for 24 months and take in notice the hashrate triples (at least) every year, this worthless crap will only mine 0,08 \ 0,09 BTC in 24 months with free energy taken!!
IF you have to pay for your energy like the most of us, it is nothing more then a doorstop.

People wake up! Almost EVERY miner you can buy from now on, WILL GIVE YOU A LOSS!

The market is so fucked, controlled and manipulated by the big boys that only they will make money on the ASICS they sell. We passed the point that mining is profitable for the home boys and medium mining companies.

It is just like the GoldFever times back then…. The only ones who make money where the ones selling the shovels, buckets, whores, siffs, etc…

WAKE UP AND STOP WASTING YOUR MONEY! (Better of buying coins and Hodl!)

Replying @People, awake please:

it almost always has been like you’re describing, but that’s not the point.
The point is to create an industry and betting on BTC/BCH future prices, like you do by buying and hold.

Selling whores is always good money like the first happy miner said above.
