ANTMINER S21 Hydro, SHA-256, super efficiency with a top hashrate! Enter a new era of liquid cooling!

Bitmain revealed Groundbreaking S21 Hydro at World Digital Mining Summit 2023

BITMAIN revealed its flagship Antminer S21 Hydro at the World Digital Mining Summit 2023. The summit, took place in Hong Kong from September 22nd to 23rd, carried the theme “Building up for the Bull Market, Mining at the Right Time.”

The S21 Hydro is the latest in Bitmain’s liquid series, achieving an efficiency of 16 J/TH. This marks a significant leap from previous models like the S19 XP Hydro at 20.8 J/TH .

Sales will open in Q4 but delivery is planned Q1-Q2 2024.
