Bitmain has launched the new Antminer T19 excavator.

The world's leading mining equipment manufacturer Bitmain has launched the new Antminer T19 Bitcoin Mining ASIC.

As announced on June 1, Bitmain's new Antminer T19 features a SHA256 hashrate running at 84 terahash / second with a 3% margin of error and an energy efficiency of 37.5 joules / terahash with a 5% margin of error.

The new ASIC model will be sold on the official website of the manufacturer from today, and shipping will start between June 21-30.

The chips used in the new device are the same as in the Antminer S19 and S19 Pro, but it also uses the new APW12 power supply and updated firmware. These changes supposedly allow for faster machine start-up and optimization of mining processes.

Riccardo Mori, manager of a small Venezuelan mine, said the T19 is significantly improved over the T17 and its introduction is likely to increase Bitcoin's hashrate.

The T19 announcement follows recent reports from the crypto community that the recently launched Antminer S17 + by Bitmain was buggy. Co-founder of the US-based consulting and mining company Wattum Arseniy Grusha, which deals in cryptocurrencies, said:

"I've never seen an excavator this bad before."

Shortly after the May criticism, Bitmain confirmed that many of the ASICs in the series had serious problems. A spokesman for the company told Cointelegraph that the company is already talking to customers who have been wronged by the situation.
