Bitmain’s D7 ASIC miner is designed to work with the X11 hashing algorithm. It uses 3148W of electricity and can generate 1286GH/s. The miner is still one of the most robust and productive X11 machines. With the Antminer D7 you can mine Dash (DASH), Onix (ONX) and other cryptocurrencies that use the X11 algorithm.
The Antminer D7 was released in 2021 and was the first ASIC miner specifically designed for mining Dash. As such, it does not have a direct predecessor within the Antminer series.
