Previously, we wrote about the long-awaited novelty from Canaan called Avalon miner A9 at 7nm and a performance of 30 TH / s. Recently, Canaan has published the characteristics of the Avalon Miner A921 asic with a much smaller 20 GH / s hash, but with an energy consumption of 1700W, as previously stated for the 30GH / s model. Energy efficiency at 0.085 J / GH in this case is not much better than long-obsolete Asic at technology 16 nm from Bitmain. On the assurances of the developers this ashik is assembled on chips with a production technology of 7 nm, but we have great doubts on this score. Because already announced 7nm asics from other manufacturers promise energy efficiency several times better at 0.03-0.04 J / GH.
The cost of the AvalonMiner A921 has not yet been announced, but most likely the price will be in the range of 500-1000 USD considering the mediocre characteristics.
Technical specifications Canaan Avalon Miner A921:
- HashRate: 20 TH / s,
- Power consumption: 1700 W
- Energy efficiency: 0.085 J / Gh
- Asic chips: 104x A3206 7nm
- Operating temperature: -5 to +30 degrees Celsius
- Dimensions: 378 x 170 x 155 mm
- Net weight: 5.5 kg
If you go to the site Asicmainervalue.com, then the presented novelty will be somewhere in the middle of the list of asics under the SHA-256 algorithm with an income of 2.17USD per day
