On 27 February, Bitmain officially announced the Antminer S19 and S19 Pro. Equipped with a custom-built 7nm chip from Bitmain and enhanced circuit architecture, the Antminer S19 series reset the industry standards with record-breaking power efficiency. The Antminer S19 Pro features a hash rate of 110 TH/s, and an impressive power efficiency of 29.5±%5 J/TH. The Antminer S19 is equipped with a hash rate of 95 TH/s, and power efficiency of 34.5±%5 J/TH. S19 Pro and S19 strongly proved Bitmain’s outstanding innovation capability and position as a leader in the market.
On June 1st, Bitmain launched the Antminer T19, which is housed with the same generation of custom-built chips found in the Antminer S19 and S19 Pro. Utilizing the new APW12 power supply and upgraded firmware, the T19 offers faster start-up speeds for an optimized mining experience. The T19 is equipped with a hash rate of 84 TH/s ± 3% and has a power efficiency of 37.5 J/TH ± 5%. Comparing with the previous Antminer T17, the T19 greatly improves performance, allowing miners to achieve better efficiency and earnings.
